Use a cylinder with a hidden airway and fill the engine with a conventional airway

The invention relates to an engine which is matched with a modified combustion chamber having a function wave and an ignition device for an internal combustion engine having a movable receiving electrode and a micro-action electrode, and a periodic function Gibbs overshooting convergence wave Fuli blade wall The engine and the engine in the scavenging passage are equipped with a valve-controlled pre-combustion scavenging and a right-hand crankshaft housing with a multi-perforated partition wall to turbulently sweep the engine, and the improved invisible air passage is provided. The cylinder is filled with a conventional scavenging air engine and belongs to the field of internal combustion engines.

Background technique

Ignition devices used in combustion equipment, especially gasoline engine spark plugs, are widely used to introduce pulsed high-voltage currents into the combustion chamber, so that the mixture drawn into the cylinders is sparked and ignited, thereby diffusing combustion and exploding work. Between the external coupling of the existing spark plug and the spark cap with the rubber shell, there is sometimes a loose phenomenon. The inside of the existing spark plug has a glass sealant as a resistor, but only has an impedance; if an inductive reactance and a capacitive reactance are added, a suitable RCL loop is formed, which is more effective in suppressing radio interference. The plurality of umbrella ribs on the insulator can also be modified from a semi-circular cross section to a zigzag cross section to allow more insulation of the creepage passage and better jamming of the rubber casing. The heat dissipation of the metal casing of the existing spark plug can be further improved. The electrodes of the existing spark plugs are conceivable, and have the disadvantages of easy carbonation, easy ablation, single-point flashover, and low temperature difficulty; if the electrode is reformed to be movable, there is improvement. In addition, the original combustion chamber has a variety of, but not perfect; in addition to the advantages, there are deficiencies; for example, the wedge-shaped combustion chamber, the mixture is excessively concentrated in the spark plug, the working conditions appear rough; The bathtub-shaped combustion chamber has a flat and long shape, which makes the squeezing effect relatively poor, the flame propagation distance is long, the burning rate is relatively low, the burning time is long, the pressure rise ratio is low, and the surface volume ratio F/V is large. It is unfavorable for HC emissions. Another example is a bowl-shaped combustion chamber, a hemispherical combustion chamber, a canopy combustion chamber, and other types of combustion chambers, such as an auxiliary combustion chamber that generates turbulence, a double spark plug combustion chamber, and a flat combustion chamber, each having its own merits; There is no end to it, and the piston has great potential to dig. The so-called optimal geometry of the combustion chamber and the piston is important, but it has to be adapted to the engine model and to the ignition device. In particular, the two-stroke gasoline engine is less economical than the four-stroke gasoline engine, and the hydrocarbon emissions in the exhaust gas often exceed the standard. The combination of the combustion chamber and piston of the internal combustion engine and the ignition device is a difficult problem involving energy saving and emission reduction. Such products can be further improved, and it is believed that some of the devices manufactured by the inventors in foreign countries, especially in Switzerland, as high-tech SENIOR ENGIN EER, have been modified to be specially tailored, and the invention can make the product one level higher. floor.

Then use the equation to enter the CNC machining center, use CIMATRO or MASTCAM to die-cast aluminum alloy steel mold, or use milling machine, planer and EDM; when using EDM, input the CNC machining center with the equation, then It is necessary to first produce a tungsten-copper electrode; then mass-produce it with a die-casting machine with a cold-pressing chamber or a hot-pressing chamber; and then machine it. The piston multi-purpose material is aluminum alloy ZL109, or AC8A. In high-end conditions such as racing cars or military vehicles, the material of the piston close to the surface of the combustion chamber is either a highly thermally conductive material such as a silver alloy; or a high temperature resistant material such as a silver tungsten copper alloy or even a special high thermal conductivity material such as synthetic diamond.

In the gap, in particular, the gap of the polygonal pyramid is locally increased, so that the position where the fire nucleus is formed is partially away from the wall surface, and there is a buffering zone, which can avoid the influence of residual exhaust gas stagnating near the wall surface, and at the same time, the sharp gas collision of the mixed gas and The turbulence effect, together with the fretting and tremor effects of the electrode tip (11) and the electrode tip (12), increases the absolute number of mixtures in the gap and increases the probability of ignition. In addition, the cusp collision and turbulence The flow is also beneficial to repel the flow of carbon deposits, and the mixture of liquid liquefaction tends to be in the inside of the tip and the basin-shaped gap, which not only has the opportunity of arc discharge, but also has a drum discharge of the electric discharge machining discharge, so that the comprehensive effect is Spark discharge quality is improved, work The performance is better.

Although the degree of heat value of a general spark plug is divided into 5-13 according to the internal structure of the spark plug according to the engine, the larger the value, the closer the cold type is, and it is suitable for the engine with high speed and high compression ratio; the smaller the value is The closer to the hot type, the lower the compression ratio of the engine; but difficult to judge from the appearance of the spark plug, or confusing. There are two advantages in the slotting of the electrical conductor of the connector of the spark plug. One is that the degree of heating of the spark plug is not easily confused, and the second one is that the connector of the original single-circle head is formed by slotting. The claw shape makes the bolt better. The slotted electrical conductor of the coupler (1) is a spark plug of a rubber or plastic insulative housing that is connected to the high voltage external wiring and is within the conductive socket within the cap.

Other features of the outer indexing high-pressure coupling (1) with indexing (1a), serrated umbrella edge (1c), fixed pit (1b) and internal thread are: said serrated umbrella edge ( 1c), as shown in Fig. 5, Fig. 6 and Fig. 9, Fig. 10, the outer zigzag and the central axis are relatively slow, so that the socket of the spark cap is easier to insert; and the zigzag and the central axis on the inner side The angle is steeper and larger, so that the socket of the spark cap is not easy to come out. As shown in Fig. 5, Fig. 6 and Fig. 7, Fig. 8, Fig. 9, the groove depth is half of the total length of the coupling; the fixing pit (1b) is provided at the end of the ungrooved end, that is, the inner end, so as to be knocked Hit fixed.

The heat dissipating fins have at least one, or two, three or more. The advantages of the fins being hexagonal are two. One is that it is easy to be machined with the hexagonal wrench nut on it, and the other is that the socket wrench can be inserted deeper when it is easy to install.

As a modification 1, the present invention particularly improves that a conventional single flat electrode is a curved electrode (16); characterized in that: the curved electrode (16), as shown in Fig. 28, is extended by a projection (16a) ( 16b), composed of a bent portion (16c), the three portions are equal to the spacing of the discharge electrodes, thereby forming a discharge gap (20) between the electrode and the discharge electrode, and longer than the original array, facilitating the mixed gas in the gap. An increase in the absolute number and an increase in the probability of ignition is another advantageous effect of the present invention.

As an improvement 2, the present invention particularly improves the electrode as an electrode (121) having a plurality of side faces and a multi-fold gap, as shown in FIGS. 14 and 7, 8, 8, 9, and 11, which are characterized in that not only the foregoing The protrusion (16a), the curved portion (16b), and the curved portion (16c) are formed, and the three portions are equal to the spacing of the discharge electrodes, thereby forming a discharge gap between the electrode and the discharge electrode, and is larger than the original front. The long feature is also specially provided with a plurality of pointed notches (17) to facilitate discharge; each of the electrode rods (10) is connected to the electrode (121), and a gap is formed in the middle of the electrode (121). ), it is beneficial to open the discharge channel. Such an electrode (121) can also use only half of the combustion chamber to save material.

As a modification 3, the present invention particularly improves the electrode as an electrode (21) having a plurality of sides and a plurality of gaps, as shown in Figs. 15 and 16, 17, and 18, which are characterized in that not only the above-mentioned projecting portion (16a) The curved portion (16b) and the curved portion (16c) are formed. The three portions are equal to the spacing of the discharge electrodes, thereby forming a discharge gap between the electrode and the discharge electrode, and are longer than the original array. There are a plurality of pointed notches (17) to facilitate discharge; each of the electrodes is connected to the electrode; as shown in FIG. 18, the electrode (21) having multiple sides and multiple gaps is provided. The middle portion of the discharge gap (20) has a lower protrusion (19), and the lower portion of the lower protrusion (19) is lower than the top of the discharge electrode, and the use thereof is to add a side discharge line. In particular, the lateral features of the electrode (21) having multiple sides and multiple gaps are at least one piece, or two or more pieces, for example three pieces. It is best to use multiple pieces to facilitate the lattice effect of the grid grid, thus increasing The possibility of electric fire core and drum discharge. As an improvement 4, the electrode (21) having a plurality of sides and a plurality of gaps or the removal of a single electrode rod, as shown in Fig. 26, Fig. 27 and Fig. 28, is characterized not only by the foregoing features, but also in particular There are electrodes (23) with multiple sides and multiple gaps of the single electrode rod. The utility model has the advantages that the material is saved, and the micro-shake between the grids of the grid is easily formed, and the carbon deposits are advantageously shaken and the discharge gap is formed by the favorable discharge gap.

As a modification 5, the electrode of the present invention is particularly improved in that the electrode is a side circular basin and an electrode (22) having an acute angled star in the middle, as shown in FIG. 19 and FIG. 20, FIG. 21, FIG. 22, FIG. 23 and FIG. The features are: a round basin with sides and an acute angled star in the middle. There are basins that have tops and sides, which add more side discharge fronts; the middle part is dug with an acute star, or a star, or two stars, or multiple stars, preferably a pentagonal star. The asymmetric multi-point random discharge channel is formed by facilitating the sharp-point effect of the discharge gap and the tip discharge effect. It is characterized in particular by an acute angle rather than a right angle or an obtuse angle.

Although the spring silkworms are dead to the end, the improvement is endless. Although the electrode (12) and the electrode housing (13) are movably assembled by the threaded or threaded groove provided in the inside of the electrode tip housing (13), there is a micro-action and the ring is received by the electrode housing. 14) Blocking, can be replaced, can also work, but in order to further enhance the fretting effect, obtain more ideal fretting and tremor effect, which is conducive to discharge and repel charcoal. As an improvement 6, the present invention particularly improves the electrode (12) The electrode tip (24) having the curved drum (24a) and the electrode tip housing (25) having the curved tip recess (25a) modified by the electrode tip housing (23a), supplemented by the other components described above, become Another ignition device for an internal combustion engine having a movable electrode and a micro-motion electrode. The electrode tip (24) of Fig. 36, Fig. 37, Fig. 38 is characterized in that an arcuate drum (24a) and a plurality of side gaps (24b) are attached to the electrode tip (12). The curved drum (24a) is matched with the arcuate concave (25a), and the upper and lower sides may have a small movable range of, for example, 0.1 mm, and at the same time, in particular, the curved drum (24a) is rotatable relative to the curved recess (25a). This is important because the rotatability of the curved bulge is better than that of the original thread or the threaded groove, so that the fine adjustment and the tendency to deposit carbon are better when the arc is pulled. The inside of the electrode tip (11) and the electrode tip (24) are similar to the electrode tip (12), and the discharge gap is formed by the top and the side of the ring, and there are multiple cutouts at the top. a sharp corner and a plurality of circumferentially threaded grooves are dug in the side of the ring; a plurality of side gaps (24b) are added, characterized in that at least one, or two, are provided on the side of the ring, or A plurality of, in particular, six through openings are provided to facilitate the flow of the mixture and to discharge carbon deposits. Because the tip (11b) of the electrode tip (11) is characterized by having a multi-sided pyramid, especially a cross-shaped pyramid, at its upper end, it is advantageous for the sharpening effect of the ignition ion current; In the basin-shaped gap between the top surface and the ring side of the spark plug, the gap of the polygonal pyramid is particularly locally increased, so that the position where the fire core is formed leaves the wall surface, and there is a buffering zone, which can avoid the influence of residual exhaust gas stagnating near the wall surface. At the same time, the added multiple side gaps (24b), in particular the curved drums (24a) can be rotated relative to the curved recesses (25a), which facilitates the sharp collision and turbulence effects of the mixture, plus the electrode tip ( 11) and the fretting and dithering effect of the electrode tip (24), the absolute number of the mixture in the gap is increased, and the probability of ignition is also increased. In addition, the impact and turbulence of the cusp are also beneficial to repel the flow of the carbon deposit. The liquefaction-prone mixture in the tip and the basin-shaped gap has not only the opportunity of arc discharge, but also the drum discharge of the EDM discharge, so that the combined effect improves the spark discharge quality and the working condition performance is better.

Because the various improvements mentioned can be selected for various models, and the advance angle can be corrected and the high-voltage pulse parameters can be adjusted for better in trial use. Therefore, the improvement 7 is proposed to make the positive and negative commutation of the high-voltage electric pulse. And change direction. Although the spark ignition process is very complicated, many aspects of humans are still unclear, but we know that the positive and negative of electricity have different effects on the loss of the discharge electrode and the electrode. Improvement 7 is a method for reducing electrode loss, which is to commutate the positive and negative voltage and current, which is easy to implement with electromagnetic and electronic circuits, such as self-excited multivibrator and differential circuit; Or with the engine Speed synchronization, or intermittent, or reversing at intervals.

Spring silkworms are inexhaustible, and there is no end to improving inventions; The present invention relates to a combustion chamber and an ignition device in a combustion apparatus, in particular, in combination with an improved functional wave combustion chamber of an internal combustion engine and an ignition device for an internal combustion engine having a movable receiving electrode and a micro-motion discharge electrode, And on the basis of a gasoline engine with a double-assisted skirt and a hydrocarbon emission reduction on the piston skirt, a further improved two-stroke gasoline engine with a sweeping airway sloping turbulence returning slab to reduce emissions is a combustion chamber of the internal combustion engine and The technical field of turbulent scavenging. The beneficial effects and objects of the invention are energy saving and emission reduction, which are beneficial for removing carbon deposits and reducing losses; improving efficiency with the function wave combustion chamber, improving combustion chamber working conditions, adding double auxiliary skirts to the piston skirt, and reducing emissions The standard effect is achieved and can be selected for various models. But the invention of human pursuit of perfection is endless, and the piston and scavenging have great potential to be dug. The so-called optimal geometry of the combustion chamber and the piston is important, but it has to be adapted to the engine model and to the ignition device. In particular, the two-stroke gasoline engine is more fuel-efficient than the four-stroke gasoline engine, and the hydrocarbon emissions in the exhaust gas often exceed the standard; the combustion chamber and piston of the internal combustion engine and the combination with the ignition device and the scavenging gas are a major obstacle to energy conservation and emission reduction. problem. If there is an unexpected effect in a gasoline engine with a double-assisted skirt on the piston skirt to reduce hydrocarbon emissions, that is, an embodiment that reduces the emission of 60 grams to 49 grams and can reach 50 grams; then, The two-stroke gasoline engine with the sweeping wedge turbulence sloping back to reduce the emission is even more unexpected. It can not only reach 50 grams, but also can be reduced to 39.9 grams. This is for large-volume two-stroke gasoline. The engine's emission reduction standards are outstanding contributions. Everyone knows that the discharge of the two-stroke machine often exceeds the standard, but no one can completely solve it; this kind of scavenging slanting wedge turbulence returns to the slap, which is a small piece in the sweeping port of the two-stroke cylinder, which seems to be simple, but no one Can think of it; no one can think of welding a small piece at the scavenging passage of the cylinder and then installing it to open the engine and contact the piston at high speed. The benefit is the unexpected reduction in emissions. Although the spark ignition process and the two-stroke detailed physical and chemical process are very complicated, many aspects of human beings are still unclear, but we may initially think that this type of scavenging channel wedge turbulence returns to the slab, and the slanting channel is inclined. The wedge creates a turbulent flow that retards the possibility of the exhaust gas returning to the intake system after combustion. It appears to be a turbulent ventilation, a well-known cross-flow scavenging, reflux scavenging, and DC scavenging for a two-stroke internal combustion engine. In terms of the three ventilation schemes, a way to reduce the turbulent flow of the wedges in the scavenging passages, which is referred to as the slanting path of the turbulent flow, is developed. Although its atomic-scale mechanism is yet to be explored in the future, its application in the two-stroke gasoline engine sweeping port has been determined.

Further improving and perfecting the engine for patrolling the air with the peripheral side oblique sweeping air passage, characterized in that it is revolutionary in the inner wall of the inner circumference of the cylinder in which the cylinder of the internal combustion engine is in contact with the piston The conventional method of opening a grooved scavenging airway having an open open-length opening along the reciprocating direction of the piston on the inner wall of the cylinder inner circumference is removed from the surface layer, thereby avoiding the piston and the cylinder. The gap between the grooved sweeping passages is mixed with the fresh charge and the exhaust gas, and the left side of the cylinder facing the exhaust port on the left side of the cylinder of the internal combustion engine is provided with a left-side oblique side scavenging air passage and in the cylinder block of the internal combustion engine. The outer side of the outer exhaust port facing the exhaust port is as shown in Fig. 136, and the oblique side scavenging air passage of the right side is reversed. The upper end of the oblique side scavenging air passage (530) is provided with a passage leading to the inner wall of the circumference of the cylinder body. The hole serves as a new scavenging passage; the through hole of the oblique side scavenging passage (530) acts as a new scavenging passage port higher than the scavenging passage opening of the conventional cylinder block (44), and is moved closer to the top dead center than the piston The 2-5mm position of the second piston ring is increased by a few millimeters above the conventional scavenging airway when fresh charge (53 1) entering the cylinder body to form a state of vortex flow along the surface of the inner wall of the cylinder circumference, so that the amount of fresh charge discharged from the exhaust port together with the exhaust gas (532) is much less. The exhaust gas is of better quality and higher efficiency, which is easy to solve and improve the fresh charge and exhaust gas of the conventional two-stroke internal combustion engine due to the simultaneous intake and exhaust process of the piston near the bottom dead center during ventilation. The residual exhaust gas coefficient is relatively large and the scavenging power consumption is large, and there are more fresh charge short circuits during the scavenging period, and directly flow into the exhaust pipe to make unburned HC emissions. High and the external characteristic curve of the internal combustion engine is steep, the economic performance of the variable operating condition is poor, and the left and right symmetrical scavenging air in the cylinder of the conventional two-stroke internal combustion engine has a collision process with the gas in the upper part of the piston in the cylinder. The problem of causing a part of the fresh charge and the exhaust gas to be easily mixed and escaping from the exhaust port together, thereby forming an engine with a peripheral side oblique side scavenging air passage to patrol the exhaust gas, which is beneficial. It is energy saving and emission reduction, reducing the mixing of fresh charge and exhaust gas.

The disadvantage of the engine of the peripheral side oblique sweeping air purging valve is that the engine on the outside of the cylinder block of the internal combustion engine faces the left side of the exhaust port as shown in FIG. The outer side of the cylinder block of the internal combustion engine faces the exhaust port on the right side as shown in Figure 136. The effect of reducing the fresh charge and exhaust gas blending is significant, but the outside of the oblique side scavenging channel is It must be matched and sealed with the attached flange, and there are more finishing and matching parts, and there are more waste products in batch production. Therefore, it is further improved and perfected, and the cylinder with the peripheral side of the airway is swept away. The scavenged engine is modified to have an engine with a hidden air passage (533) built therein and filled with a conventional scavenging air passage as shown in Figs. 139 and 140.

An engine in which a trapped air passage cylinder is built and filled with a conventional scavenging passage is characterized in that it is revolutionarily removed from the surface of the inner wall of the cylinder in contact with the piston of the internal combustion engine. a method of opening a grooved scavenging passage opening a long distance along the reciprocating direction of the piston in the inner wall of the cylinder inner circumference to thereby avoid the slotted air passage of the piston and the cylinder The gap between the fresh charge and the exhaust gas is mixed, and an invisible air passage (533) is arranged on the cylinder of the internal combustion engine, and the invisible air passage (533) has independent and straight through on the cylinder block of the internal combustion engine. a hole, the lower end of the through hole penetrates with a lower flange of the connection box of the cylinder, and an upper end of the through hole penetrates with an inner wall of the inner circumference of the cylinder to form a through hole, The intersecting through holes of the upper end of the through hole are provided at a position above and below the rounded carburetor inlet near the cylinder, and the passage of the entire air passage of the invisible air passage is invisible It is hidden in the casting of the cylinder, the invisible air passage is in the die casting mold a round bar-shaped oblique guide column is formed by die casting through a side core sliding block in the mold; the intersecting passage of the upper end of the through hole of the invisible air passage on the cylinder block of the internal combustion engine The hole is disposed at an inner wall of the inner circumference of the cylinder at a position above and below the air inlet of the oblong carburetor located near the cylinder to form a continuous through hole as a new scavenging passage; The through hole of the invisible air passage (533) acts as a new scavenging passage port higher than the scavenging air port of the conventional cylinder block (44), that is, closer to the spark plug, and the second piston ring that moves closer to the top dead center than the piston 2 -5mm position, which is a few millimeters higher than the conventional scavenging passage, and when the fresh charge (531) enters the cylinder, a vortex flow is formed along the surface of the inner wall of the cylinder circumference. Therefore, the fresh charge will be discharged from the exhaust port together with the exhaust gas (532), so that the exhaust gas quality is better and more efficient, so as to solve and improve the conventional two-stroke internal combustion engine when the piston is under the air. The fresh charge and exhaust gas are easily blended at the same time as the intake and exhaust processes near the stop point Economy with large exhaust gas coefficient and large scavenging power consumption, and more fresh charge short-circuit during scavenging, directly flowing into the exhaust pipe to make unburned HC emissions high and make the external characteristic curve of the internal combustion engine steep. Poor performance and the collision of the left and right symmetrical scavenging passages in the cylinder of the conventional two-stroke internal combustion engine into the upper part of the piston in the cylinder causes a part of the fresh charge to be easily mixed with the exhaust gas and exhausted together. The mouth ran out to form an engine with a hidden airway cylinder and filled with a conventional scavenging airway, which saves energy and reduces emissions and reduces the mixing of fresh charge and exhaust gas.

The benefits are self-evident; the manufacturing style is easy to implement.

detailed description

Referring to the overshooting convergence wave of the Gibbs phenomenon of the overshoot of the rectangular wave of the Fourier function in the mathematical physics method of higher mathematics, and the reference delay theorem, the displacement theorem, the convolution theorem, and the approximate single of the Fourier function The circular frequency is expanded to approximate the gradual attenuation of the spectrum depicted by the Fourier series. From the large to the small, the narrow peak is narrowed. The mathematical physics describes a high degree of generalization of many practical phenomena. The law of turbulent motion should not be exceptionally and completely surpassed. There should be some similar or intrinsic correlation or mutual benefit. More or less learn from it; on the molding core of the die-casting mold, the imitation is close and seems to be intrinsically related. The Fourier function notch (53j) and the upper transitional inflection point (54j) of the high wall have at least one turn shape close to 90 degrees, which approximates the Gibbs overshoot convergence wave, ie, the Fuli-like series The gradual approximation of the rectangular transitional wave drawn by the overshoot phenomenon and the gradual attenuation of the spectrum drawn by the simulated Fourier series have a plurality of undulating convexities and convexities (54k) from large to small and from narrow and dense peak waves; Cylinder shaped body as mainstay idiotypic affect airflow. The Fourier function notch (53j) with guiding and damping characteristics and the transitional inflection point (54j) of the upper part of the high wall with the linear function of the higher-order mathematical function and the Fourier shape, and the gradual attenuation of the imitation-Fourier series The undulations (54k) of the spectrum of the spectrum from large to small are more advantageous for noise high frequency band, pressure increase ratio, and compression ratio.

Referring to the quadratic function curve of the equipotential streamline of the parabolic family in the mathematical physics method of higher mathematics, it has guiding significance for the flow of multiple gas storage of the stratified gas storage piston. The outer side of the sealing wall (44e) is a parabola-type equipotential streamline on the side of the scavenging channel, which can be CNC machined. The section of the scavenging channel with logarithmic spiral can also be processed by CNC numerical control. The logarithmic spiral, that is, the equiangular spiral, has the advantage of equal pressure angle everywhere, which is beneficial to the airflow movement of the scavenging airway. The two scavenging channels are mutually matched. The first scavenging channel uses an equiangular spiral with equal pressure angles, and the second scavenging channel uses a quadratic function curve of the parabolic family of equipotential lines. The mathematical physics method of higher mathematics is the direction of research and development. It is better to use the high number of science to guide the experiment than to blindly do. What mathematical physics describes is a high-level summary of many actual phenomena, and the law of engine scavenging should not be an exception. Separately assembled (and sintered ceramic and welded electrode connecting rods) with indexing 1a, serrated umbrella edge 1c, fixed pit 1b and internal threaded externally indexed high-pressure coupling 1, gasket 2, with serrated section Multi-channel insulator 3, threaded end 4 and threaded end 4b and inductor 15 internal inductance, heat sink fin housing 5, S-shaped fixing washer 6, resistor-containing glass sealant 7, The steel core 8 is embedded, the electrode rod 9 is placed, the electrode rod 10 is received, the electrode tip 11 is received, the electrode tip 12 is received, the electrode tip housing 13 is received, and the electrode head housing retaining ring 14 is received. The electrical conductor of the externally-divided high-voltage connector 1 with the index 1a, the serrated umbrella 1c, the fixed pit 1b and the internal thread has at least one slot or a plurality of slots; preferably the number of slots is For example, if the degree of a spark plug is 6, the number of slots is 6; if the degree of a spark plug is 7, the number of slots is 7. The slotted electrical conductor of the coupler 1 is screwed into the threaded end 4 and the fixed pit 1b is tapped to make the spark plug. Screw the spark plug into the threaded hole of the engine to tightly press the S-shaped retaining washer 6. A spark cap is inserted with a rubber or plastic insulating shell to connect the electrical conductor of the connector 1 to the high voltage external wiring and to the conductive socket in the cap. When the ignition advance angle is reached, the current sequentially passes through the coupler 1, the threaded end 4 and the threaded other end 4b and the internal inductance of the inductor 15, the resistor-containing glass sealant 7, is embedded in the steel core 8, and the electrode is placed. The rod 9, the electrode rod 10, the discharge head 11, the electrode tip 12, the electrode tip casing 13, and the discharge between the discharge head 11 and the electrode tip 12. The member 4, the member 15, the member 7, the member 8, and the member 9 are surrounded by the insulator 3, especially the ceramic body, and the coupling resistance is mutually coupled. The resistor and the inductor have the effect of the series-parallel RCL equivalent circuit. Properly equipped, there is the effect of preventing radio interference. The outer casing 5 with the fins has a heat dissipating area of the fins which is much larger than the original cylinder, and It is self-evident that the heat dissipation is improved. The zigzag umbrella edge 1c of the outer indexing high-pressure coupling 1 with the index 1a, the serrated umbrella edge 1c, the fixing pit 1b and the internal thread has a slower angle to the outer zigzag and the central axis, The socket of the spark cap is easier to insert; the angle of the zigzag on the inner side is larger than that of the middle shaft, so that the socket of the spark cap is not easy to come out. The slot depth of the slot is about half of the total length of the connector; the effect of slotting and not slotting is different, and the conductor is easily expanded slightly to form a plurality of claws after the slot is formed, and the socket of the spark cap is not easy to escape. Because the outer casing 5 provided with the heat dissipating fins is characterized in that the heat dissipating fins 5a, the heat dissipating fins 5b, and the heat dissipating fins 5c are provided, in particular, the fins are hexagonal or circular, so try to The original steel material is used to make a part of the material which is to be cut off in white to form a heat dissipating fin. The heat dissipating fins have at least one or more. The fins can be machined with the hexagonal wrench nut on it. It is also convenient to install the socket wrench to be deeper and less slippery. As a modification, the present invention particularly improves the conventional single flat electrode as the curved electrode 16; characterized in that: the curved electrode 16, as shown in FIG. 15, is composed of the protruding portion 16a, the curved portion 16b, and the curved portion 16c. The three portions are equal to the spacing of the discharge electrodes, thereby forming a discharge gap between the electrode and the discharge electrode, and longer than the original array, which is advantageous for increasing the absolute number of mixed gases in the gap and increasing the probability of ignition. The residual exhaust gas at the discharge gap is expected to be cleaned, so that the mixed gas is easy to ignite, which has a great effect on the warm-up and low-load performance; however, it is not desirable to have an excessively strong airflow directly rushing toward the discharge gap at the moment of ignition, thereby blowing off the fire core. Increasing the cyclic variation rate of the pressure in the cylinder, even causing a fire, and the curved electrode 16 composed of the protruding portion 16a, the curved portion 16b, and the bent portion 16c is beneficial for this; the curved electrode 16 is also It can be matched with a function waveform piston. It is best to take 0.5-0.9 for wave height C and 15-21 for wave number N.

As an embodiment 2 of the improvement 2, since the electrode of the present invention is particularly improved, the electrode 12 is an electrode 12 having a plurality of side faces and a multi-fold gap, which has not only the aforementioned three portions composed of the projecting portion 16a, the curved portion 16b, and the bent portion 16c. The distance from the discharge electrode is equal to form a discharge gap between the electrode and the discharge electrode, and is longer than the original line, and a plurality of pointed notches 17 are especially provided. Therefore, in the first stage of the spark ignition process, the breakdown stage It is beneficial to discharge the ion current that breaks down the mixed gas from the electrode to the discharge electrode. Although the peak current is large, the time for the entire breakdown phase is very short, only ten microseconds, so a plurality of pointed notches 17 are feasible. Moreover, since each of the electrode rods 10 is connected to the electrode electrode 12, and the middle portion of the electrode electrode 12 has a multi-fold gap 18, it is advantageous in the second stage of the spark ignition process, that is, the arc phase, and in the third stage of the spark ignition process. That is, in the glow discharge stage, it is advantageous to open the discharge channel, and it is easy to make the multi-fold gap have more sparking passages, and the mixed airflow is easy to pass. The electrode 12 can also be used in only half, with a discharge gap on the top and side surfaces, which can be matched with a functional waveform piston.

As an embodiment 3 of the improvement 3, the present invention particularly improves the electrode 21 having the electrode 21 having a plurality of sides and a plurality of gaps because it has not only the aforementioned three portions composed of the projecting portion 16a, the curved portion 16b, and the bent portion 16c. Equal to the spacing of the discharge electrodes, thereby forming a discharge gap between the electrode and the discharge electrode, and longer than the original array, and further comprising a plurality of pointed notches 17; each of the electrodes is connected to the electrode to be integrated, which is convenient for manufacturing And because the middle portion of the electrode 21 having the plurality of sides and the plurality of gaps has the lower protrusion 19 at both ends of the discharge gap 20, the lower portion of the lower protrusion 19 is lower than the top of the discharge electrode, and the use thereof is increased. Side discharge front. In particular, the lateral features of the electrode 21 having multiple sides and multiple gaps are at least one piece, or two or more pieces, for example three pieces. It is preferably a plurality of pieces, so it is advantageous to form a grid grid lattice effect, thereby increasing the possibility of electric fire core and drum discharge; because under the operating conditions of the engine, the static mixed gas ignition energy only needs 0.2 mJ, The higher velocity of the mixture ignition energy requires only 3 millijoules, while the conventional ignition system supplies more than 30 millijoules, that is, 10 times the amount. Just using this feature, the multi-grid grid of the present invention is designed. Various physical fields such as power fields, electric fields, and Under the combined action of fluid field turbulence and electrochemistry, it is easy to form micro-shake between the grids of the grid, and it is advantageous to shake off the carbon deposits and form a discharge channel with favorable discharge gaps. As an embodiment 3 of the improvement 4, since the electrode 21 having a plurality of side faces and a plurality of gaps or the single electrode bar is removed, the feature is particularly characterized in that the electrode 23 having a plurality of sides and a plurality of gaps of the single electrode rod is provided. Therefore, the beneficial point is not only material saving, but also can form micro-shake between the grids of the grid, which is beneficial to shake off the carbon deposit and facilitate the discharge gap to form a discharge channel; therefore, the electrode can be used with no special protrusions and pits. Corrugated pistons.

As an embodiment 5 of the improvement 5, the electrode of the invention is particularly characterized in that the electrode is a side round basin and an electrode 22 with an acute angle star in the middle, which is characterized by a rounded basin on the side and an acute angled star in the middle; That is, there is a top surface and a side surface, so that the side discharge line is added; the middle part is dug with an acute angle star, which means that the angle of the star claw protruding from the star is an acute angle; the characteristic is especially the acute angle, instead of Right angle or obtuse angle. Or a star, or two stars, or a plurality of stars, preferably a five-pointed star, so it is beneficial to the sharp-point effect of the discharge gap and the tip discharge effect to form an asymmetric multi-point random discharge channel, which is beneficial to increase the discharge. The possibility and removal of carbon deposits, the sharp-pointed star electrode is conducive to the continuation of the spark effect and the spark front distortion caused by turbulence, the molecules interpenetrate, and the turbulent flow rate increases. The electrode is adapted to be matched with a wave piston having a spark pocket 36.

The ignition device for internal combustion engine with active electrode and micro-motion electrode has self-micro-motion function and replaceable electrode core, which can be exchanged for a long time. Since the electrode 12 and the electrode housing 13 are movably assembled by the threaded or threaded groove provided in the inside of the electrode tip housing 13, there is a micro-action, and the electrode housing casing retaining ring 14 blocks, and can be replaced. It can work, but in order to further enhance the fretting effect, a more ideal fretting and tremor effect is obtained, which is advantageous for discharging and repelling coke. As an improvement 6, the present invention particularly improves the electrode 12 as the electrode tip 24 having the curved drum 24a. And the improved electrode tip housing 13 is an electrode tip housing 25 having an arcuate recess 25a, supplemented by the other components described above, and becomes another ignition device for an internal combustion engine having a movable receiving electrode and a fine movement electrode. Due to the electrode tip 24, a curved drum 24a and a plurality of side gaps 24b are provided. The curved drum 24a is slightly movable with the curved recess 25a, and the upper and lower sides may have a small movable range of, for example, 0.1 mm, and at the same time, in particular, the curved drum 24a is rotatable relative to the curved recess 25a, so the rotation of the curved concave concave It is better than the original thread or thread groove, so the fine adjustment and decoking tendency is better when the arc is pulled; the first lower breakdown when discharging, the second and the next is still easy to hit. In the part, due to the shaking and fine movement of the electrode, especially in the place where the two electrodes were last broken, the relatively fixed discharge position is not fixed and avoided, thereby shifting the multiple discharge places. In each discharge, the electrode molecules are depleted into a gaseous state, so the benefit is that it is self-evident that the life of the electrode is prolonged and the carbon deposition is facilitated. The jitter and fine motion of the electrodes, especially the rotation, are readily available under vibration conditions within the kinetic energy engine. Since the inside of the electrode tip 11 and the electrode tip 24 are similar to the electrode tip 12, the discharge gap is formed by the shape of the top and the side of the ring, and there are a plurality of excavated sharp corners at the top and The side of the ring is dug with a plurality of circumferentially threaded grooves to facilitate arcing.

In addition, the special improvement 7 is to make the positive and negative commutation and direction of the high-voltage electric pulse, and also try. Although the spark ignition process is very complicated, many aspects of humans are still unclear, but we know that the positive and negative of electricity have different effects on the loss of the discharge electrode and the electrode. Improvement 7 is a method for reducing electrode loss, which is to commutate the positive and negative voltage and current, which is easy to implement with electromagnetic and electronic circuits, such as self-excited multivibrator and differential circuit; Or it may be further improved by synchronizing with the engine speed, or intermittently, or at intervals. The various improvements mentioned are beneficial to increase the possibility of discharge and to remove carbon deposits and reduce electrode loss.

The invention relates to energy saving and emission reduction, and is a two-stroke gasoline engine which sweeps pre-combusted gas in a scavenging passage. The cylinder (44) comprises a vent (44a), a gas inlet (44b), and left and right sides. a symmetrical air inlet port (44c), a symmetrical first scavenging port (44d) on the left and right sides, and a symmetrical second scavenging port (44f) on the left and right sides, and the outer side of the closed sealing wall does not depend on the piston cylinder One side of the scavenging passage is curved and co-located with the outer process piece (55) of the scavenging passage of the cylinder block, and the process piece (55) is provided with a spacing 楞 (55 g), a gap notch (55e), a scavenging side wall (55d), a second scavenging side wall (55d), three mounting holes and a profiled gland, forming a scavenging air passage having a cavity, and the piston (31) is provided with a storage of each of the left and right sides Pit (31a).

A two-stroke gasoline engine with a filter screen valve controlled pre-combustion scavenging in the scavenging passage is characterized in that it is substantially near the top dead center of the piston, before the mixture on the piston that has been compressed in the cylinder is ignited, due to the piston The skirt is moved up to open the preliminary suction port in the opening and closing cylinder, and the mixture of fuel and air is sucked in the crankcase below the piston; and the piston is dead due to the pressure of the combustion gas above the piston generated by the ignition Move to the bottom dead center and close the suction port at the same time, compress the mixture in the crankcase, and pass the combustion gas in the cylinder to the outdoor air from the opening and closing exhaust port on the piston near the bottom dead center. a scavenging passage connecting the crankcase and the cylinder, and a two-stroke engine that introduces the mixed gas from the crankcase into the cylinder by the preliminary scavenging port in the cylinder on the upper and lower sides of the piston; the design has a valve device synchronized with the crankshaft, and the valve is From the crankcase to the cylinder scavenging port, the crankcase side of the scavenging passage is configured to be normally closed; when the valve on the crankcase side of the scavenging passage is closed, the mixing in the scavenging passage is The combustion gas is ignited by the flame of the combustion gas, and after the HC is reduced, the crankcase is opened from the crankcase to the scavenging port, and the crankcase side of the scavenging passage is opened, and the combustion mixture in the scavenging passage is sent out while being in the crankcase. The exhaust gas closes the exhaust port before being discharged from the exhaust port, which is a two-stroke engine that significantly reduces the HC discharge; and in the previous structure, the valve in the same period as the crankshaft described above is not designed, the flame of the combustion gas If the scavenging port is not opened after the disappearance, the flame of the combustion gas will cause the mixture in the scavenging passage and the crankcase to ignite, so that the mixture cannot be supplied into the cylinder, and the opening of the exhaust port will cause the opening of the scavenging port to pass. When it is opened early, when the exhaust port and the scavenging port in the cylinder are simultaneously opened, the unburned mixture in the crankcase and the scavenging passage enters the cylinder from the exhaust port, so a part of the mixed gas is in an unburned state. The exhaust port is discharged, which becomes a problem of an increase in the mixed gas (ie, HC) in the exhaust gas; the present invention is outside the scavenging port of the intake port exhaust port, after the crankcase is scavenged, and the scavenging gas is passed through. An open/close valve is added to the crankcase side of the road, and the mixture in the scavenging passage is ignited and burned in the flame of the combustion gas, and the valve in the scavenging passage and the crankcase is synchronized according to the crankshaft, so the crankshaft is cut off. The mixture in the tank will not burn, and the combustion gas in the scavenging passage will be squeezed out in the cylinder during the valve opening in synchronism with the crankshaft, at the exhaust port and the scavenging port. At the same time of the initial opening, the combustion gas in the scavenging passage is supplied into the cylinder, and the exhaust gas discharged from the exhaust port to the outside is not doped with HC, and when the exhaust port is about to be closed, the scavenging passage is closed.

The key to the design is that the piston moves from the top dead center to the bottom dead center and closes the suction port at the same time. That is, the length of the piston matches the distance of the air port in the cylinder. This is not difficult to mark on the drawing, and the processing is not difficult. The effect is to reduce the amount of exhaust HC.

The core slider is die-cast; the new scavenging air passage of the invisible air passage is higher than the scavenging air passage of the conventional cylinder (44), that is, closer to the spark plug, and the second piston ring moving closer to the top dead center than the piston The lower 2-5mm position is increased by a few millimeters above the conventional scavenging airway. When the fresh charge (531) enters the cylinder, it forms a vortex on the surface of the inner wall of the cylinder. The state of the fresh charge will be much less out of the exhaust port along with the exhaust gas (532).

Claims
