Abstract

PURPOSE: An evaporator for an internal combustion engine capable of regulating the over supply of combustion air is provided to actively supply air for combustion needed depending on the increase of suction pressure in an engine by installing an over supply regulator. CONSTITUTION: A regular suction pressure is generated by operatingan internal combustion engine. Air intaken from an air cleaner inflows a throttle body(102) through an air cleaner conduit(15). Herein, the intaken pressure is weak in an idling state of the internal combustion engine so that it does not overcome the pressure of an elastic tool. Air flows in through only an outside air supply hole of an outer body. When the suction pressure toward a cylinder increases due to the increase of RPM(revolution per minute) of the internal combustion engine, the air amount passing through only the outer air supply hole is not sufficient. The excessive air pressure presses a valve cap after entering an auxiliary chamber. Under a stronger pressure force than the elastically supportive pressure of the elastic tool, the valve cap is pushed. Then, combustion of fuel is perfectly accomplished with the sufficient amount of air.

Description

Air intake system for internal combution engine, capable of supercharging combustion air

The present invention is additionally installed in the carburettor inlet or blow-by-gas valve conduit or air filter of the internal combustion engine, the air supercharge control means that can be actively controlled in accordance with the rotational speed of the engine to maximize the fuel combustion of the internal combustion engine, Inside the carburetor, it relates to an internal combustion engine provided with a separate vortex forming means. In addition, one end is connected to the outside and enclosed space, such as the inside of a passenger car or a trunk separate from the internal combustion engine, and the other end is connected to an arbitrary position between the air cleaner and the surge tank so that the indoor air is drawn directly into the engine. The air supply is related to a new carburetor structure that enables the function of indoor air purification by allowing the indoor odor to be burned by inhalation.

The internal combustion engine obtains the target kinetic energy by supplying fuel and air at the optimum ratio in the engine cylinder and then exploding the combustion. At this time, since the mixing ratio of fuel and air varies depending on the amount of combustion air supplied therein, there is a difference in explosive power. Although the theoretical air-fuel ratio for fuel and air is admitted as 1: 14.8, the generation of NOx is inevitable at high speeds because the cylinder temperature changes according to the driving environment, and at low speeds, sufficient combustion cannot be achieved due to weak suction power. .

In the patent application No. 9343 dated March 18, 1998, the inventors installed a conduit bypassed from the air cleaner to the surge tank, or a bypass conduit with a control unit, and another auxiliary conduit was installed on the bypass conduit. This allows sufficient air supply through the original suction conduit and other passages. As a result, the fuel in the engine was burned close to the complete combustion, so as to achieve the purpose of increasing power output and reducing soot. In addition, another bypass conduit was installed so as not to go through the throttle chamber, or in conjunction with the axel pedal, the valve opening operated so that the required air was supplied smoothly.

In addition, various developments have been attempted to obtain fuel efficiency improvement and output increase by means of vortexing the air supply into the combustion chamber or minimizing the amount of fuel supply at a certain speed or more.

Although the above invention has been achieved to some extent to achieve the desired complete combustion by supplying sufficient air, the function of more actively operating in accordance with the engine speed and the rotational speed (RPM) of the piston must be achieved through the central control unit. There was a disadvantage. And even if the control is such that when the MAP sensor, O2 sensor, etc. are aged, the action of these sensors is uncertain, and in the case of a certain period of time, the vehicle has almost no effect. In addition, even if the desired amount of inhalation is controlled by a certain control means, it is not always possible to accept changes in the external air environment, which is constantly changing due to the characteristics of the vehicle, and the small combustion environment due to the deterioration, deformation, or fuel difference of the vehicle. As a result, it is not possible to achieve the desired level of fuel reduction or soot reduction.

The present invention allows the opening degree to be mechanically adjusted according to the sound pressure generated according to the piston rotational speed (RPM) of the internal combustion engine, and the air directly supplied to the surge tank in the room according to the deterioration degree of the vehicle, the characteristics of each manufacturer, etc. The new carburettor structure can be controlled by direct visual control without modifying the central operation control device of the vehicle, and also detects the pressure of the accelerator pedal to control the degree of air supply. It is also an object of the present invention to provide a device that can be installed at any time without any structural changes or modifications of the current vehicle, but also actively accepts various variables according to the variation of the vehicle in use. According to the present invention, a manual supercharger is installed in an interior of a vehicle as well as an engine room to completely burn fuel while simultaneously removing and removing dirty air in the room.

The present invention is connected between the surge tank 110 and the air cleaner 40 for supplying air to the engine body 100 by the air cleaner conduit 15, the amount of air introduced from the throttle body, the intake temperature, The nozzle opening degree of the fuel to be supplied by calculating the suction pressure and discharge pressure supplied from conduits such as O2 concentration of exhaust gas, suction air pressure, blowby gas side pressure, pressure adjusting side pressure, exhaust gas return conduit, etc. by a constant control means. In the intake system of an internal combustion engine configured to control and supply the air-fuel ratio in an optimal state by determining

It has an outer body 1 having a diameter capable of closing the inlet portion 14 of the throttle body 102. The inner body 2 having a small diameter is formed integrally with the outer body 1 concentrically. , And an intake system of an internal combustion engine provided with a boost regulator (A) for closing the auxiliary chamber (10) formed inside the inner body (2) with the valve cap (9) carried by the burner (7). .

In the present invention, the supercharge adjusting device (A) is concentric with one tension adjusting device 6 while the outer body 1 and the inner body 2 having a cylindrical structure have different diameters as shown in FIGS. 4 to 7. Integral to the shaft, the outer end portion (1a) and the front end portion (2a) has a structure in which a plurality of external air pores (3) and internal air supply holes (4) are formed through, and the auxiliary chamber (10) inside the inner body (2) The main body 11 was formed inside the outer body 1 in association with the outer body 1 so as to form different spaces between the outer body and the inner body. At the center of the main chamber 11 and the auxiliary chamber 10, a tension adjusting device 6 is installed to press the valve cap 9 toward the inner body side by the tannery 7, and a tension adjusting device 6 ) Arbitrarily sets the compression strength of the bullet strip 7 by adjusting the engagement distance with the fixture 5. The external pore 3 and the internal pore 4 formed at each end of the supercharge regulator can be set and changed in number and size according to the diameter of the inlet 14, and may be polygonal or elliptical in addition to a simple circle. If the air flow rate is constant, any form can be applied. If the valve cap 9 installed in the auxiliary chamber 10 of the supercharge regulator covers the entire auxiliary chamber 10 and closes the internal pores 4, in addition to the hat shape as shown in the figure, any shape such as disc, cap, circle, etc. It is also applicable to the form. In the case of the hatshade is the most preferable form that minimizes the flow resistance of the incoming air, the end is configured to be inclined to enable the sealing function when in contact with the valve seat (8). The control means 1b having the same diameter is provided at the outer end portion 1a of the outer body 1 of the supercharge regulating device, and this control means is provided by the fixing means 1c as shown in FIG. It is a donut-shaped thin plate structure in which adjustment holes 1d of the same size are formed to partially close the pores 3.

As shown in FIG. 1, the supercharger adjuster has a diameter almost the same as that of the inlet of the throttle body 102, by using an interference fitting or fastening means such as bolts or rivets. By fitting, it is fixed to the inlet at the carburetor inlet. In addition, in order to ensure the ease of attachment and detachment of the supercharge control device to constitute a slight curved portion on the periphery will belong to the same category. The supercharge control device of the present invention has the same effect even when installed at either the end of the air cleaner conduit 15 or the inlet to the trolley body. In other words, if it is installed in front of the throttle valve, the supercharge function does not change.

The vortex means installed in the inlet portion 14 shown in Figs. 2 and 3 is described in Patent No. 144075 of the present invention, which differs from the pre-registered at the outer circumferential end of the vortex fan 100 at a protective support. 101 is to install. That is, it is installed to prevent the vortex fan from entering into the engine due to excessive air supply, thereby preventing the metal crushing particles from entering the engine in advance. In addition, when the support 101 is deformed in the form of a carburettor, the intake air can be accelerated to further promote atomization of the fuel to be introduced.

The operation relationship using the control apparatus which has the above basic structure is demonstrated.

The internal combustion engine is operated to generate a suction pressure of a constant pressure so that the air sucked from the air cleaner enters the throttle body 102 through the air cleaner conduit 15. At this time, if the internal combustion engine is idle without load, the suction pressure is weak. Therefore, the air pressure is adjusted so as not to overcome the pressure of the bullet port 7 supporting the valve cap 9. It flows through only the external air hole (1) of (1). If the RPM of the internal combustion engine is increased and the suction pressure to the cylinder side is increased, the amount of air passing through only the external air supply hole 3 is not sufficient, so the excessive air pressure eventually enters the auxiliary chamber 10 through the internal air supply hole 4 to open the valve. The cap 9 is pressed. When the pressing force is stronger than the pressure of the pressure strip (7), the valve cap (9) is pushed out so that the air flowing in both directions of A and B. That is, a sufficient amount of air is supplied to make the combustion of the fuel more perfect.

As another embodiment of the present invention as shown in Figure 3 fixed by a separate pivot pin 13 to the inlet portion 14 of the throttle body 102 in the state in which the supercharger according to the configuration of Figure 1 is installed Install the control wing (12). The control wing 12 is always pulled in the direction opposite to the C by the not illustrated bullet strip, so that when the pressure of the incoming air is increased, the control wing 12 is opened as shown by the arrow C. The installation of the above auxiliary control wing 12 delays the opening of the valve quickly or vice versa even when the pressure increases excessively momentarily or suddenly decelerates, resulting in poor combustion due to the richness of fuel or lean fuel concentration. It eliminates the knocking phenomenon and enables the optimum combustion. In this case, the elastic strength of the ballistic zone exhibiting a return function may be adjusted in consideration of various variables depending on the type of vehicle or the degree of aging.

In the present invention, the control means (1b) installed in the out end portion (1a) of the supercharge control device is different from the necessary amount of intake air through the air supply hole in accordance with the characteristics of the vehicle or the internal combustion engine in the case of simply installing the above basic supercharge control device If this is the means for the user to manually adjust. That is, the contro means are rotated slightly as shown in FIG. 7, and then the fixing means 1c are dismantled so that the air supply holes are partially closed by the control holes 1d, and then fixed by using the fixing means. The amount of suction through the air supply hole is adjusted. Therefore, it is possible to supply an appropriate air in accordance with the characteristics of the vehicle or the amount of air required.

As another object of the present invention as shown in Figs. 8 to 10, the bypass conduit 34 in which the electronic boost controller (b) is disposed in the middle of the blow-by gas conduit 33 through the T-shaped conduit 33a. It is installed to be connected to the air cleaner conduit 15, to delete the supercharger (A) that was installed in the inlet of the trolley body (102). Here, the electronic turbocharger (B) is configured to form a main chamber 21 in the center of the cylindrical body portion 20 so as to penetrate up and down, and one side forms an inclined portion 22a to form a small hole 22b at the end of the inclined portion. At the other end, a screw part is configured to be joined to the joint 29. In this main chamber 21, the bullet strip 23 pushes the valve body 24 toward the small hole 22b at all times, and the bullet strip 23 has a plurality of through holes 26 formed in the center thereof. The control rod 27 fixedly extended to the upper side is fastened to the upper side of the valve body so as to be elastically adjustable by the retainer plate 25 in which the screw portion 28 and the outer circumferential surface are screwed. The outer side of the small holes 22b constitutes the primary air chamber 30 while the electromagnet 34 is fixed by the bracket 28, and the inner valve body 24 and the bullet holes 23 are built in the outer valve. The small hole 22b was sealed or opened in cooperation with the packing part 37 in the upper part of the body. The packing part 27 was formed in the center upper part of the outer valve body 35 so that the pore 22b may be closed at the time of the pressurization of the bullet port 31. On one side of the outer valve body 35, the air inlet path 29 is formed in the horizontal direction to allow the air flowing through the place. In addition, the electromagnet 34 and the axel pedal are connected to a switch circuit (not shown), so that when the pedal pressure is applied, electricity to the electromagnet is energized. The magnitude of the voltage applied to the electromagnet can cause the voltage delivered to be increased or decreased using a potentiometer such as a potentiometer operating in response to the pressure of the accelerator pedal. In other words, the flow rate of the air can be adjusted by allowing the valve body 23 to be constantly changed in accordance with the pedal pressure of the axel.

As another embodiment of the present invention shown in Figure 11 is to omit the control rod 37 of the electronic supercharge adjusting device (b) so that the upper end of the tanji 23 is in direct contact with the joint (29). That is, by adjusting the insertion pressure of the joint support 23 into the body portion 20 of the joint can be adjusted to the level desired by the user.

The operation relationship according to the configuration of FIGS. 8 to 11 is described above.

When the internal combustion engine operates and the pressure drawn from the cylinder is not strong, air is constantly introduced through the normal air intake passage. When the driver steps on the accelerator pedal, electricity is supplied to the electromagnet 34 through a sensing device (not shown). Therefore, the electromagnet 34 is excited and the valve body 35 pushed by the bullet strip 31 retreats, and the small hole 22a which the packing part 37 pressed and closed is opened. At this time, the degree of opening is that when the axel pedal pressure is high, the valve body retreats further back by the force of the electromagnet that is excited by a large magnetic force, thereby increasing the opening degree of the pores so that the flow of the flow becomes more smooth. When the pores are opened, the air is sucked in by the suction pressure of the blow-by gas conduit 33, and the air is introduced. When the air is introduced more strongly than the pressure of the bullet strip 23, the inner valve body 24 is pushed upward and opened. More air is coming in. In this case, if the retainer plate 25 is fixed to a predetermined position by using the control rod 27, the retainer plate 25 can raise or lower the pressing force of the carbon support 23 so that the opening degree can be arbitrarily adjusted. In other words, the user can arbitrarily adjust according to the type or characteristics of the vehicle and can maintain the optimum combustion state according to changing the vehicle's age or desired fuel consumption from time to time.

Another object of the present invention is to install a manual turbocharger in the necessary portion as shown in Figures 11 and 12 to allow sufficient air supply. Specifically, the electronic supercharger shown in FIGS. 5 and 6 omits the electromagnet and the valve body 35 according to the electronic supercharger, and is configured to always open the small holes 22b. And the fine adjustment part 51 and the precision adjustment part 52 are provided in the side surface of the valve body 55. The fine adjustment unit is a place where a controller 51d for adjusting the opening degree of the fine adjustment path 51c is installed while rotating the adjuster 51b with respect to the reference ruler 51a. An adjustment bolt 52b configured to move up and down by a screw part 52a vertically opened in the middle while the open precision adjustment path 52c is formed is assembled, and the adjustment of the diameter equal to the diameter of the precision adjustment path 52c is performed. The bolt is configured to close the fine adjustment furnace 52c when fully tightened. And there is formed in the center of the cylindrical body portion 55, the main chamber 56 is formed so as to penetrate up and down, one side constitutes the inclined portion 57 to form a small hole (58) at the end of the inclined portion, the other end of the screw portion (59) was configured so that the joints 65 were fastened. In addition, the main chamber 56 presses the bullet strip 60 to always press the valve body 61 toward the small holes 58, and the bullet strip 60 has a plurality of through holes 62 formed in the center thereof. The control rod 53, which is fixedly extended in the vertical direction, is vertically fastened so that the threaded portion 59 and the outer circumferential surface thereof are elastically adjustable by the retainer plate 64 screwed together. The retainer plate 64 screwed to the threaded portion 59 of the body portion 55 is provided with a plurality of air outlet paths 62 on the outside thereof, and the control rod 53 is fastened to the center thereof, whereby it is fixed as necessary. Make it variable.

The operation relationship of the manual turbocharger described above will be described taking the case of being installed in the air filter as shown in FIG. A filter is built in the air filter 40, and the installation position is at the bottom of the filter. In this state, the control rod 53 is appropriately adjusted so that the retainer plate 64 presses the bullet strip 60 at a constant level. Therefore, basically, the small holes 58 are always kept open so that the air passing through the filter is supplied there through. However, when the air pressure is weak, the pressure of the bullet zone 60 holding the valve body 61 cannot be overcome. Therefore, the air supply function is only as large as the opening of the fine adjustment unit 52 and the precision adjustment unit 51. It is supplied with In this state, if the air suction pressure is further increased, excess air is supplied to the main chamber 56 through the small holes 58 in addition to the fine adjustment unit 51 and the fine adjustment unit 52. It is. That is, the amount of air sucked while excessive consumption of fuel, such as high-speed driving, is supplied to a sufficient amount of air by their action so that there is no problem such as incomplete combustion or increase in soot. In addition, the user can adjust the amount of inhaled air precisely by adjusting the controller 51d of the fine adjustment unit 52 or adjusting the adjustment bolt 52b of the fine adjustment unit 51 according to the state of the vehicle. It is. That is, while adjusting step by step centering on the reference (51a) to adjust the degree of opening in consideration of the exhaust state, fuel economy, etc. of the exhaust. Therefore, if the desired level of fuel economy and soot emissions is set, the internal combustion engine continues to operate in that state.After a certain period of time, the fuel economy and soot are measured. To maintain state.

Looking at the operation relationship according to the above configuration is to enable the suction of another air simply by using the suction pressure stayed in the sensing of the pressure sucked into the surge tank. Therefore, it is possible to supply a constant air in accordance with the pressure of the surge tank. This air supply can be adjusted by the user comparing the generation of smoke and the increase and decrease of fuel efficiency according to the opening degree of the valve, and can be adjusted together considering the relationship of the output. The above manual turbocharger can be installed in another space besides the air filter unit to obtain the same effect, and the same effect can be obtained even if the small holes 58 are packaged in a separate filter and directly exposed to the outside of the engine.

The manual supercharge regulator is not installed in the air filter as described above, but is installed in the same place as the air cleaner conduit 15, or in the case of a passenger car, where the outside air can be filtered first, such as the indoor side and the trunk room. The same effect can be obtained even if arranged.

In addition, as shown in FIG. 13, it is wrapped in a filter layer 70 suitable for openings such as the small holes 22b, the fine adjustment unit 51, the fine adjustment unit 52, etc., which are the inlet side of the manual turbocharger, so that external air does not directly penetrate. You can get the same effect by configuring. That is, after the filter layer 70 is installed and installed in the engine room or the vehicle interior, the degree of opening is adjusted by the fine and precision adjusting unit, and the air required for combustion is directly injected through a path other than the air filter to completely burn the combustion. It is to promote.

In the present invention, reference numeral GP is a gas supply conduit, 101 is a distributor, and 103 is a manifold pressure sensor.

The present invention uses a combination of a turbocharger, an electronic turbocharger, a manual turbocharger and a manual turbocharger with a filter to keep the amount of air supplied to the combustion air of the engine as optimal as possible. Therefore, in low speed operation in accordance with the operating conditions of the internal combustion engine, the pressure required for the operation of the supercharge regulator is not generated, so the supply of air remains at the normal level. However, in the case of high-speed driving or overload condition, the suction pressure is greatly increased, so that the air supply port 4 of the turbocharger is pushed in, so that sufficient air can be supplied through the internal air supply hole 4, thereby promoting combustion and sufficient output. Will be done. In particular, an internal combustion engine using LPG as a fuel can prevent the increase in smoke and the decrease in output caused by excessive fuel air and the resultant insufficient combustion.

The control wing 12 provided for another object of the present invention is to ensure a smooth operation by buffering the sudden air blocking or excessive air supply generated during rapid acceleration or deceleration here.

The electronic supercharge adjusting device (B) provided for another object of the present invention is capable of exciting the electromagnet 34 according to the pedal pressure of the pedal and thus opening or closing the valve cap. Therefore, when the axel pedal is excessively pressed and the supply of air is insufficient, it is possible to induce a more smooth supply of air out of the normal intake pipe here.

Manual turbocharger provided for another purpose of the present invention is to adjust the three supply paths of the fine control unit, the fine control unit and the main supply passage adjusted by the valve body embedded in the main chamber at a predetermined position of the air supply passage to meet the required level To control it. The level of adjustment can be determined by looking at the desired soot reduction, increased output, or various desired levels. The best part is that the user can adjust and reinstall the device at any time. Therefore, by looking at the state of the engine, the user can adjust the degree of output and smoke generation as required, so that even the old vehicle can always maintain the best state.

In other words, the optimum air-conditioning ratio can be obtained by setting the most optimal condition externally according to the aging degree, characteristics of the engine, and even the characteristics of the driver. In the engine running condition, these devices can be adjusted until the target combustion rate is achieved.
