Description
Affiliated technical field:
What the present invention relates to is a kind of " environmental protection and energy saving two-stroke gasoline engine R type ".For motive power machine equipment, especially use pure fuel oil work and changed the lubricating condition of main engine-part, change the physical arrangement of motor gas port, strengthen the ability of scavenging, changed the job specification of former two stroke engine, increased complete machine working life, strengthen merit the output of merit, main is to have solved original two stroke engine severe discharge is caused to the pollution serious to environment, the large situation of symbol and " energy-saving and emission-reduction, low-carbon (LC) life ".
Background technique:
The present invention's " environmental protection and energy saving two-stroke gasoline engine R type " be former take gasoline on the basis of fuel two stroke engine, for accomplishing of making that motor does the best in the time that work is done increases the service life, give play to best effect and used most economical fuel and the discharge of the minimizing Litter of doing the best and designing.The structure of former two-cycle engine.Piston, piston ring, the little axle of piston, crankshaft bearing and bent axle stub bearing all must be by mixing oil lubricating few in gasoline, reduce greatly to the working life of component because working in worst situation, this namely gas car why do not use the main cause of two-cycle engine, be just out of order with several days motors, must keep in repair.Separately, piston is to arrive combustion gas before bottom dead center, almost suction port is also opened simultaneously, put into fresh inflammable gas, it seems now that the intake and exhaust of two original stroke gasoline engines are on same point position, suction port in fact or lower than relief opening, and fresh inflammable gas sprays in cylinder block by the pressure of paying compression of crankcase again, also will be by having the new inflammable gas of pressure outside waste gas kickoff mechanism, and piston stroking upward also needs first to close complete suction port, then finish relief opening closing.Because residual waste gas is by having outside the combustible gas kickoff mechanism that pressure is new, so just to have the inflammable gas also not burning that some is new, will take outside machine with waste gas.So not only wasted the energy, but also serious pollution physical environment.Although the designer of former motor, the suction port by motor as possible designs more than 45 °, in order that allow the upwards operation as possible in the time entering firing chamber of new inflammable gas, so that emptying waste gas, cannot process but also have nearly 35% dead angle area, can affect the power of motor, and cut here, the fresh inflammable gas that has 25%-40% is pushed out outside machine, and this has not only caused the waste of the energy, has also caused the pollution of environment.Eventually above-mentioned situation institute extremely, in the large situation of " environmental protection and energy saving, low-carbon emission " at present in addition, existing two rush gasoline journey motor, will exit historical stage.But it is simple in structure for two journey motors, to pay and do manual work less, output power is powerful is the strong point of its maximum.The output power of two stroke gasoline engines, normally with 106 times of discharge capacity four-stroke gasoline engine output power, accordingly, deep research and development and the improvement of two stroke gasoline engines, still very promising, accordingly, deep research and development and the improvement of two stroke gasoline engines, still very promising.
---descending air-breathing---up compression---outburst acting that four-stroke gasoline engine does program from work and opens and make: piston stroking upward scavenging.What between whole 720 °, only have 180 degree is in operation acting, and other 540 degree are all to pay acting, and this plays that code should be called is intermittent type acting, and this can reduce the power of motor naturally, when the work of single cylinder small displacement engine, can feel to be short of power.
Summary of the invention:
In order to solve deficiency more than original old-fashioned two-cycle engine, " environmental protection and energy saving two-stroke gasoline engine R type ", is upgrading again and is improving original motor.In the time of the structure of designed engines, for the weight that alleviates original motor of a most step, it is simple in structure that newly-designed two stroke engine designs as possible, and we know, any equipment, and its another parts are various, and its working resistance will be larger.And another parts are various, in the time of work, also just more easily break down, another parts are various, and the cost of its manufacturing and maintenance is also just higher, consuming time also just longer, and another parts are various, will increase the volume and weight of this equipment.Therefore the design of this motor, accomplish as possible simple in structure, economy and durability.And adjust and improve for the deficiency of original two stroke engine, and retain the strong point of original motor, newly-designed motor is reached and given play to better using effect.Analysis conclusion is that the performance of a motor and work are done principle mainly: air inlet, compression, outburst acting, exhaust.So just, can find out, the performance of two stroke engine depends on the ability of scavenging process to a great extent, the process of scavenging is also one of emphasis of two stroke engine research always, highly organized scavenging process, obtain the combustion gas of large as far as possible fresh abundance, bring into play maximum acting for cylinder and there is unusual important meaning, be to adopt the method for numerical simulation to go research, but prerequisite condition also must provide the pre-compressed gases of enough brute forces, only have rationally entering and advancing of enough pre-compressed gases, well new gas and the good scavenging of supply.Certainly the comprehensive whole installation in gas port place, exhaust smooth and easy, all vital, the physical angle stranding that designs air inlet makes air-flow fling parallel propelling behind the waste gas bottom relative with relief opening, see Fig. 7,8 pages, the loss of the fresh inflammable gas of minimizing as possible, the loss of fresh inflammable gas herein of the two-stroke gasoline engine in past is many at 25% 40% one by one, see Fig. 9 (54), resolve the loss that reduces as possible fresh inflammable gas herein, saving exactly the energy increases the key position of power.Environment-friendly and energy-efficient two stroke engine can make the number of dropouts of fresh inflammable gas be reduced between 5%-0.0% to design and processing herein, the dead angle area of simultaneously also well having processed exhaust, the residual quantity of waste gas is reduced in 5%, the design is here, can utilize waste gas more so residual, just can ensure that live gas is not running off.Like this, not only save the energy, also increased the power of motor simultaneously.Also have in addition the very important point to be exactly: good lubricated, only have good lubricating the working life that can increase motor, want to accomplish that environmental protection and energy saving and long service life just must make an effort in this link.In the time that reality is implemented, change the historical custom of mixing gas and oil that uses of former two stroke gasoline engines, change to be made as and use pure gas and oil, be conducive to environmental protection, changed scavenging way and the piston profile of original two-cycle engine, and the profile of gray iron, make fresh precompression inflammable gas, after entering cylinder block, fling behind dead angle area, parallel pushing ahead, the loss that is conducive to emptying waste gas and control live gas is conducive to save the energy and increases power.Change the working method of former two stroke gasoline engines main parts and strengthened lubricating condition, for utilizing oil pump to directly lubricated and inorganic oil pump splash lubrication (inorganic oil pump lubrication herein refers to and is applicable to horizontal engine or opposed engine) of cylinder body portion, make machine oil directly to firmly wanting easily damaged parts to be lubricated, thereby increase and extended the working life of motor.The design of this two stroke engine, takes pains emphasis simple in structure, and lightweight volume is little, practical, newly-designed " environmental protection and energy saving two-stroke gasoline engine R type " usage range is wider, and the cost of the manufacturing is lower, thereby reduce car load price, and manufactured and keep in repair more convenient.
Newly-designed two-stroke gasoline engine has changed the historical miscella that uses of two stroke engine to the lubricated mode of main engine-part, be designed to use machine oil directly to implement lubricated to sending out which main part: after improving by the two stroke engine analysis to original, first lubricated improvement the at the gentle cylinder body position, bent axle position to motor, change original two stroke engine tradition use herein oil-in-gasoline lubrication, use the directly bent axle position to the machine lubricated in crankcase portion of machine oil, in Fig. 5, the machine bent axle position lubricated done to detailed signal and explanation.The mode of lubricated work is herein, the machine is that machine oil is added in engine oil chamber (47), engine oil chamber does not communicate with crankcase, and the oil inlet hole (69) of bent axle and oil outlet (70) are all provided in a side of engine oil chamber (47) the inside.Lubricated working principle herein, to have utilized the principle of centrifugal mechanics to participate in work, the oil inlet hole for machine (69) of design and machine oil oil outlet (70) here, to have designed all rate variances of an eccentric circle and centrifugal differential seat angle, the all rate variances of eccentric circle are the central position that machine oil oil inlet hole (69) is provided in a side of circumference, and the machine oil oil outlet (70) of design is the outermost circle place at circumference.Centrifugal differential seat angle is that the oil inlet hole place of design has utilized one large section of bottom horizontal flow sheet in circle center position, and the oil outlet of machine oil (70) is the differential seat angle at design and oil inlet hole (69) right angle in 90 °, like this, as long as engine operation will produce centrifugal force, this centrifugal force naturally can make machine oil locate constantly to flow to outside at oil outlet (70), the machine oil here also will naturally enter and do to supplement from oil inlet hole (69), here if the oil level of engine oil chamber design when too high, can locate to add a bit of straight tube () in oil outlet (70) and increase centrifugal force, to guarantee herein lubricated.As for the stub bearing (34) of bent axle and lubricating of the little axle bearing of piston (17), also be by centrifugal force, machine oil to be transported to herein, but be all forward that road without other can be walked in their theres, implementing good lubricated effect so also have to unified locating to flow out and reach at oil outlet (70).In Fig. 4, the true lubrication circumstances at the cylinder body position to the present invention's design that main is, do with detailed signal and explanation, change too here original two stroke engine, the mode of traditional use oil-in-gasoline lubrication, use instead and utilized machine oil directly directly lubricated to the another parts such as cylinder body, piston, piston ring, the lubricant oil of design logical (11) here, that design is located at the cylinder body portion body (71) of the cylinder body of motor, and with the parallel position of cylinder block lubrication hole (53), the oil leab (72) of an annular is set.Like this, when lubricant oil is by being arranged on the oil leab (11) of body (71), being sent to annular oil leab (72) locates, because annular oil leab (72) communicates with cylinder block lubrication hole (53), lubricant oil just can enter into by cylinder block lubrication hole (53) inwall of cylinder block, implement lubricated to cylinder block (13) and piston (16) and piston ring (15), here just can very clearly see by A figure in 8 pages of figure of accompanying drawing and B figure, no matter piston is at top dead center, or all cannot get out of the way cylinder block lubrication hole (53) in lower dead center, to ensure that lubricant oil cannot trickle freely in the inwall of cylinder block herein.Design herein, the motor of vertical working is will use oil pump in this way, but horizontal motor or the motor of opposed type in this way, because lubricant oil can naturally trickle to this position, can save oil pump.
Newly-designed two-stroke gasoline engine; after having changed at 2, become the historical feature that uses miscella work of motor; change the pure fuel oil work that uses that is made as; stop the severe contamination that the severe discharge of original two stroke engine causes environment; meet the requirement of discharging standards; accomplish low-carbon emission, protected physical environment.
The design of newly-designed two-stroke gasoline engine piston: see Fig. 6, that approximately 1/13rd place, the front top of piston (16) is designed to air inlet cambered surface point convex (8), and in being provided with upwards by precompression suction port (5) one side pistons the air inlet of the camber cambered surface (7) of regulating the flow of vital energy, be beneficial to new pre-compressed gases and enter and directly rush at after cylinder block (13) behind the bottom that cylinder cap front end enters cylinder block waste gas, while turning back to form straight expansion fan-shaped and better release the waste gas in cylinder.This design is main for solving new pre-compressed gases to enter circulation angle after cylinder block (13) smooth and easy, can do fine processing to the waste gas of the dead angle area (77) of former cylinder inner casing postoperculum gets rid of, the firing chamber of this motor is just located at the rear top of piston (16), and it is designed to the firing chamber (4) of lower concave arc shape.
The design of newly-designed two-stroke gasoline engine cylinder block working method: see figure, that the body (71) of the cylinder body of motor is located, and between cylinder block (13), be provided with oil leab (11), this oil leab communicates with engine oil chamber (47) by oil pump below, top communicates with the oil leab (72) that is located at cylinder block middle part and arranges an annular, and the oil leab (72) of annular communicates with cylinder block lubrication hole (53).
Newly-designed two-stroke gasoline engine changes the physical arrangement of having established gas port, process to detailed scavenging work and the design of scavenging mode are done to illustrate below: in two stroke engine, the function of gas port is very crucial, asks for an interview Fig. 8 in the processing of this gas port.A in figure, piston stroking upward is implemented compression to inflammable gas in cylinder, the plug ignition compressed combustible gas in cylinder that ignites during to top dead center, the combustible gas after outburst starts acting, promotes descent of piston.Piston now down to before bottom dead center time, is need first will open relief opening (14) to see B in figure, and the waste gas in cylinder block is implemented to scavenging, first discharges most of waste gas.Piston continues descending, and then open precompressed air suction port (5), start to inject fresh combustible gas in cylinder block, from figure, in C, can be clearly seen that, fresh combustible gas just flings the bottommost place of waste gas in cylinder block after entering in cylinder block, then clean thoroughly by the waste gas release in cylinder.Piston continues descending, and porting is all opened, and whole scavenging work completes.The matrix firing chamber of piston when the design here, before slightly height a bit, become arc smoothly just to exhaust port, again exhaust port height reduced and do the best and grow here, be beneficial to the quick discharge of waste gas.And then with regard to the inlet hole of opened precompressed air, be here far from being enough by being originally arranged at that angle on casing wall regulates the flow of vital energy, also therefore just can cause the loss of a large amount of new inflammable gass to see figure.To have utilized after the function of new design piston herein, in the time opening precompression suction port, fresh precompression inflammable gas, just arranged by the air inlet of the piston cambered surface control of regulating the flow of vital energy, directly rush at the bottom of the exhaust dead angle area that cylinder head cannot process originally, the rounded convex that utilization is arranged at thick stick lid front portion is advancing gas to the rear portion of cylinder head, for new gas can be promoted smoothly, the Cylinder head design is here tiltedly straight type, mobile like this gas has not just had any resistance yet, suction port is opened larger and larger, because new inflammable gas is by the sequencing that enters cylinder, at the whole installation in conjunction with cylinder cap place, making new inflammable gas form a straight shape pushes ahead, the design here, it is all unresisted smooth and easy shape, be conducive to outside whole waste gas kickoff mechanisms, guaranteed that new combustible gas is not running off from relief opening simultaneously, stop former two stroke engine 25%-40% energy waste.
The adopted technological scheme of dealing with problems is:
In the time of the specific works of motor, when piston (16) goes upward to top dead center, design is the firing chamber (4) with cylinder head (3) composition at piston concave shape place (9), now plug ignition, the compressed combustible gas outburst acting of igniting.Piston is promoted descending by pressurized gas, extremely before bottom dead center time, start scavenging in cylinder.The firing chamber (4) that the rear top design of its piston (16) is lower concave arc shape, and tiltedly straight type is located and be designed to the cylinder head of firing chamber (3), the air inlet of the sharp convex (8) that approximately 1/13rd place, front top of piston (16) is designed to the concave cambered surface (7) of regulating the flow of vital energy, all to be beneficial to new pre-compressed gases to enter and directly rush at after cylinder block (13) behind the bottom that cylinder cap front end enters waste gas, while turning back to form straight expansion fan-shaped and better release the waste gas in cylinder.The design of cylinder head, cylinder block, one group of another parts of piston is herein main for being to solve new pre-compressed gases to enter circulation angle after cylinder block (13) smooth and easy, can do fine processing to the waste gas of the dead angle area (71) of former cylinder inner casing postoperculum and get rid of, see 7 pages, accompanying drawing.When this is in descent of piston, new inflammable gas in crankcase (45) is carried out to precompression.The now precompression of crankcase completes substantially, and compressibility inflammable gas enters in cylinder block from suction port (5) through pressurized air gas-entered passageway (6), releases to injecting new inflammable gas in cylinder block the waste gas having burnt simultaneously.Bent axle (22) remains in operation through after bottom dead center, and piston (16) is opened and made uply, automatically shuts relief opening (14).Piston continues up, inflammable gas new in cylinder block is compressed to (this is called positive compression) until when top dead center, spark plug (1) igniting, the inflammable gas explosive combustion acting of igniting after compression, motor enters next work and does program.
The performance of machine oil is not only just lubricated, and also has sealing and cleaning etc. to do use.In other words for motor, that fills part makes good use of machine oil, the working life that just can extend complete machine not merely, but also can improve the power of motor.The design proposal of this motor is accordingly: by cylinder block lubrication hole (53), to piston (16), piston ring (15) is lubricated and seals.Herein, in the bottom of piston (16), be provided with piston bottom oil ring (21), purposes is to stop machine oil to enter crankcase (45), separately can make on the inwall that is applied to cylinder block (13) of the more equal rhythm of machine oil, make the better effects if of lubrication and seal, the design of this piston base ring, while going upward to top dead center, be in relief opening (14) bottom, prevent from directly machine oil being caused to waste outward at relief opening kickoff mechanism, in addition, the design of position, lubricating cylinders hole (53) also as possible away from relief opening a bit.The machine oil that enters the oil leab (29) of bent axle work is implemented lubricated by bent axle stub (32) to crankshaft-link rod bearing (34), pass through bent axle chain bar (20) to the little axle bearing of piston (17), the little axle of piston (19) is implemented lubricated again.For preventing that machine oil from locating to flow into crankcase (45) at bent axle stub (32) and the little axle of piston (19), ad hoc meter has located to add special bent axle master pin oil (33) and the little shafting oil envelope of piston (18) at bent axle stub (32) and the little axle of piston (19).The mode of lubricated work is herein, the machine is that machine oil is added in engine oil chamber (47), engine oil chamber does not communicate with crankcase, and the oil inlet hole (69) of bent axle and oil outlet (70) are all provided in a side of engine oil chamber (47) the inside.Lubricated working principle herein, to have utilized the principle of centrifugal mechanics to participate in work, the oil inlet hole for machine (69) of design and machine oil oil outlet (70) here, to have designed all rate variances of an eccentric circle and centrifugal differential seat angle, the all rate variances of eccentric circle are the central position that machine oil oil inlet hole (69) is provided in a side of circumference, and the machine oil oil outlet (70) of design is the outermost circle place at circumference.Centrifugal differential seat angle is that the oil inlet hole place of design has utilized one large section of bottom horizontal flow sheet in circle center position, and the oil outlet of machine oil (70) is the differential seat angle at design and oil inlet hole (69) right angle in 90 °, like this, as long as engine operation will produce centrifugal force, this centrifugal force naturally can make machine oil locate constantly to flow to outside at oil outlet (70), the machine oil here also will naturally enter and do to supplement from oil inlet hole (69), here if the oil level of engine oil chamber design when too high, can locate to add a bit of straight tube in oil outlet (70) and increase centrifugal force, to guarantee herein lubricated, this straight tube must be to add installing after crankcase.As for the stub bearing (34) of bent axle and lubricating of the little axle bearing of piston (17), also be by centrifugal force, machine oil to be transported to herein, but be all forward that road without other can be walked in their theres, implementing good lubricated effect so also have to unified locating to flow out and reach at oil outlet (70).

by centrifugal force, machine oil to be transported to herein, but be can walk without other road there at them, so also have to unified locating outflow and reach the good lubricated effect of enforcement at oil outlet (70), in 4 pages, accompanying drawing, the true lubrication circumstances at the cylinder body position to the present invention's design that main is, do with detailed signal and explanation, the lubricant oil logical (11) here, that design is located at the body (71) of the cylinder body of motor, and with the parallel position of cylinder block lubrication hole (53), the oil leab (72) of one annular is set, like this, when lubricant oil is by being arranged on the oil leab (11) of cylinder body body (71), being sent to annular oil leab (72) locates, because annular oil leab (72) communicates with cylinder block lubrication hole (53), lubricant oil just can enter into by cylinder block lubrication hole (53) inwall of cylinder block, implement lubricated to cylinder block (13) and piston (16) and piston ring (15), here just can very clearly see by A figure in 4 pages of figure of accompanying drawing and B figure, no matter piston is at top dead center, or all cannot get out of the way cylinder block lubrication hole (53) in lower dead center, to ensure that lubricant oil cannot trickle freely in the inwall of cylinder block herein, design herein, the motor of vertical working is will use oil pump in this way, but the motor of horizontal motor or opposed type in this way, because lubricant oil can naturally trickle to this position, can save oil pump, vertical engine is equipped with oil pump (31) oil lubricating road (11) in the crankcase portion (5 pages, accompanying drawing) of complete machine, to cylinder block (13) piston (16), piston bottom is provided with bottom oil ring (21), the design of piston: see Fig. 6, that approximately 1/13rd place, the front top of piston (16) is designed to air inlet cambered surface point convex (8), and in being provided with upwards by precompression suction port (5) one side pistons the air inlet of the camber cambered surface (7) of regulating the flow of vital energy, being beneficial to new pre-compressed gases enters and directly rushes at after cylinder block (13) behind the bottom that cylinder cap front end enters cylinder block waste gas, this design is main for solving new pre-compressed gases to enter circulation angle after cylinder block (13) smooth and easy, can do fine processing to the waste gas of the dead angle area (77) of former cylinder inner casing postoperculum gets rid of, the firing chamber of this motor is just located at the rear top of piston (16), it is designed to the firing chamber (4) of lower concave arc shape, physical arrangement physical design and the scavenging process of gas port are shown in accompanying drawing 8, A in figure, piston stroking upward is implemented compression to the inflammable gas in cylinder, the plug ignition compressed combustible gas in cylinder that ignites during to top dead center, combustible gas after outburst starts acting, promote descent of piston, piston is now down to before bottom dead center time, need first will open relief opening (14) to see B in figure, waste gas in cylinder block is implemented to scavenging, first discharge most of waste gas, piston continues descending, and then open precompressed air suction port (5), start to inject fresh combustible gas in cylinder block, from figure, in C, can be clearly seen that, fresh combustible gas just flings the bottommost place of waste gas in cylinder block after entering in cylinder block, then clean thoroughly by the waste gas release in cylinder, piston continues descending, porting is all opened, whole scavenging work completes, the matrix firing chamber of piston when the design here, omit height a bit above, become smoothly arc just to exhaust port, here again exhaust port height reduced and do the best long, be beneficial to the quick discharge of waste gas, and then with regard to the inlet hole of opened precompressed air, here far from being enough by being originally arranged at that angle on casing wall regulates the flow of vital energy, also therefore just can cause the loss of a large amount of new inflammable gass to see accompanying drawing 9 (54), to have utilized after the function of new design piston herein, in the time opening precompression suction port, fresh precompression inflammable gas, just by the air inlet of piston regulate the flow of vital energy cambered surface (7) control arrange, directly rush at the bottom of the exhaust dead angle area that cylinder head cannot process originally, the rounded convex that utilization is arranged at thick stick lid front portion is advancing gas to the rear portion of cylinder head, for new gas can be promoted smoothly, the Cylinder head design is here tiltedly straight type, mobile like this gas has not just had any resistance yet, suction port is opened larger and larger, because new inflammable gas is by the sequencing that enters cylinder, at the whole installation in conjunction with cylinder cap place, making new inflammable gas form a straight shape pushes ahead, the design here, it is all unresisted smooth and easy shape, be conducive to outside whole waste gas kickoff mechanisms, guaranteed that new combustible gas is not running off from relief opening simultaneously, stop former two stroke engine 25%-40% energy waste, 10 pages, special oil sealing accompanying drawing is mainly used to bent axle stub (32) and the little axle of piston (19), and to locate main be sealing machine oil, 10 pages, special oil sealing accompanying drawing is provided with abrasion-resistant metal ring (67), and special oil adhesive body sealing lip (68) must not be higher than abrasion-resistant metal ring, interchangeable of the intake and exhaust of this motor are used, the present invention is suitable for one-way valve, rotary valve, piston valve type uses.
