Description

Environment-friendly and energy-efficient two-stroke opposed type is without crank crank-axle engine

Affiliated technical field:

What the present invention relates to is a kind of " environment-friendly and energy-efficient two-stroke opposed type is without crank crank-axle engine ".For motive power machine equipment, the design of this motor can be petrol engine, also can be diesel oil motor simultaneously, and the weight that has alleviated motor of several times, because its lightweight power is designed to greatly aviation special engine.Especially job specification and the operating conditions of former motor have been changed, increase the working life of complete machine, strengthen the output of engine power, solve the problem of the severe discharge of original two-cycle engine to severe environmental pollution, the large situation in the world of echoing " energy-saving and emission-reduction; low-carbon (LC) life ", its profile is flat round edge stereoscopic rectangular.Background technique:

The present invention's " environment-friendly and energy-efficient two-stroke opposed type is without crank crank-axle engine " is on the former basis with " environment-friendly and energy-efficient two-stroke opposed engine ", for increasing the service life of making that motor does the best in the time that work is done, give play to best using effect and used most economical fuel and the discharge of the minimizing Litter of doing the best, vibrations while effectively alleviating engine operation and make its stable working and design.The structure of the two stroke engine of former history is, piston, and piston ring, the little axle bearing of piston, crankshaft bearing and bent axle stub bearing must be to be all lubricated by mixing lubricant oil 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 the horizontal line of 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, simultaneously also by the new inflammable gas that has pressure outside waste gas kickoff mechanism, and piston stroking upward also needs first to close complete suction port, then closing complete relief opening.Because residual waste gas is will be by having outside the combustible gas kickoff mechanism that pressure is new, this is because of the reason of old-fashioned two stroke engine working principle of design, so just can 25%-45% between the new inflammable gas also not burning, will be with waste gas outside discharge machine.So not only wasted the energy, but also serious pollution physical environment.Although the designer of former motor, the suction port place of motor is designed more than 45° angle as possible, 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 the power that affects motor that this just can be serious but also have nearly 35% dead angle area.Having, original motor vibrations sensation in the time of work is large, and Zhao sound is large and the three-dimensional upwards center of gravity of motor is large, and the vehicle that arrives is turned dangerous in the time running at high speed, topmost or main engine-part lubricating ability is poor, working life is without guarantee, and serious severe tail gas pollution, and above-mentioned situation institute extremely eventually, in in addition at present " environmental protection and energy saving, low-carbon emission " the large situation in the world, existing two-cycle gasoline journey motor, will exit historical stage.

Four-stroke gasoline diesel engine from work do program open make be:---descending air-breathing---up compression---outburst acting, a work journey system finishes in piston stroking upward scavenging.Entering the lower up scavenging of program of using.This sees between whole 720 °, only has 180 ° to be to implement 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.And, inlet and exhaust valve, camshaft, push rod, the moving of a lot of another parts such as valve spring cooked, and also all must consume a large amount of power.But two journey engine structures are simple, and every 360 ° of actings once, again without the resistance of any attached acting.Pay and do manual work less, just increased the output of power, therefore output power is powerful is the strong point of its maximum.The output power of two stroke gasoline engines originally, normally in 1.6 of same discharge capacity four-stroke gasoline engine output power---between 1.8 times, and also has the simple feature of lightweight small volume structure, accordingly, deep research and development and the improvement of two-stroke gasoline engine, still very promising.

Practicability from two-stroke machine to Lightweight Vehicles: due to two stroke engine than four stroke engine weight, power, safety, reliability, etc. each side have more advantage, so in the practicability of light-duty traction use, adopt two stroke engine be natural non-it do not belong to.In motor weight reduction, that is to say and alleviated burden can have larger carrying capacity or have better mobility.What between current, this advantage showed on the first-class dilly of four-wheel wagon is also also few.But the sea, land and sky of trailbike motion, with the field such as the empty emergency in extraordinary military Hangzhoupro in, be definitely that first two stroke engine charges and shatters enemy positions.The two stroke engine in past, because severe discharge, the society that is applied in of two stroke engine is limited by very large. but along with the reform and development of a technology such as such as in-cylinder direct injection and perfect, the emission problem of two stroke engine will be able to comprehensive solution, and two stroke engine also will be light and handy because of it, simple and reliable for structure, the advantages such as specific power is large are widely used, because the each stroke of two stroke engine has acting, so it has very high power ratio, also due to simple in structure, there is again the weight--to-power ratio of the discrepancy in elevation, the ratio ratio of volume ratio ratio and production and processing maintenance cost, and the position in her is possessed and control at station fast, her effect and speciality are given play to.

Summary of the invention:

Invention introduction: in order to solve deficiency more than original old-fashioned two-cycle engine, " environment-friendly and energy-efficient two-stroke opposed type is without crank crank-axle engine ", is upgrading again and 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 that changes equipment.Therefore the design of this motor, accomplish as possible simple in structure, economy and durability.

And done the analysis of filling part for original two stroke engine, and the deficiency of original two-stroke gasoline engine is adjusted and improved, 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, bringing into play maximum acting tool for cylinder has very great significance, 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 5,7 pages, accompanying drawing, the loss of the fresh inflammable gas of minimizing as possible, the two-stroke gasoline engine in the past herein loss of fresh inflammable gas is many 25%---and 40%, see that in figure, (35) are located, 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 to 5% to design and processing herein---between 0.0%, 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 reservation waste gas more so residual, just can ensure that live gas can not run 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 actual design is implemented, change the historical custom of mixing gas and oil that uses of former two stroke gasoline engines, change and be made as the pure oil inflame workmanship of use, solve the original severe discharge of two-stroke gasoline engine, be conducive to environmental protection.Scavenging way and the piston profile of original two-cycle engine are changed, 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 utilize oil pump to cylinder body portion directly lubricated and inorganic oil pump splash lubrication (inorganic oil pump lubrication herein refers to and is applicable to horizontal engine or opposed engine, vertical engine is to need to use oil pump), 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, take pains emphasis simple in structure, lightweight volume is little, practical, newly-designed " environment-friendly and energy-efficient two-stroke opposed type is without crank crank-axle engine " usage range is wider, the cost of manufacturing is lower, thereby has reduced car load price, and manufactures and keep in repair more convenient.

Concrete invention: newly-designed two-stroke opposed type is without the design of crank crank-axle engine working method: after improving by the two stroke engine analysis to original, find two original product journey gasoline engines, all utilize crankcase to implement precompression, by feeling after concrete analysis, utilize crankcase precompression, not only complex manufacturing, and main be to have increased after the volume of crankcase, can affect the ability with compression, can be better and use attached cylinder to implement precompressed effect, but its another parts will be more a lot of, design is herein, without crankcase precompression, also need not compress by attached cylinder, but vertical implement to produce pre-compressed gases with this cylinder, this has not only simplified technological process, and main be to have increased precompressed ability, can provide more sufficient precompressed air to motor.

The design of newly-designed two-stroke engine lubrication mode: 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, because do not using crankcase to implement compression, just change crankcase into engine oil chamber, use machine oil directly the bent axle position of the machine to be implemented lubricated in crankcase portion.

Newly-designed two stroke engine, lubricating system to the another parts of cylinder block and the piston ring etc. of motor is also changed, change the mode of two-stroke gasoline engine tradition use herein oil-in-gasoline lubrication, be designed to use machine oil directly to implement lubricated to another parts herein.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 to cylinder body, piston, the another parts such as piston ring are directly lubricated, the cylinder body portion engine oil chamber (24) of design here, the body place of design at the cylinder body of motor, and communicate with the oil lubricating hole (7) that is located at cylinder body, machine oil just can directly enter into the inwall of cylinder block like this, implement lubricated to cylinder block (5) and piston (4) and piston ring (3), 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 (7) 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.

The design of newly-designed two stroke engine piston: see attached 6 pages, that approximately 1/13rd place, the front top of piston (4) is designed to sharp convex, and leaning on precompression suction port (25) one sides, the air inlet of the camber cambered surface (31) of regulating the flow of vital energy in piston is provided with upwards, be beneficial to new pre-compressed gases and enter and directly rush at after cylinder block (5) 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 cannot process original two stroke engine, the waste gas of the dead angle area (37) of cylinder block inner casing postoperculum does fine cleaning and gets rid of, the firing chamber of this motor is just located at the rear top of piston (4), it is designed to the firing chamber (2) of lower concave arc shape, the exhaust of its piston setting cambered surface (32) of regulating the flow of vital energy, in order that make exhaust more smooth and easy.

Newly-designed two stroke 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 5 pages, accompanying drawing in the processing of this gas port.A in figure, piston stroking upward is implemented compression to the inflammable gas in cylinder, spark plug during to top dead center (1) igniting, compressed combustible gas in the cylinder that ignites, 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 to see that B in figure (6) locates, and the waste gas in cylinder block is implemented to scavenging, now first discharges most of waste gas.Piston continues the descending C in figure that sees, and then open precompressed air suction port (25), start to inject fresh combustible gas (33) 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 block.Piston continues the descending figure D that sees, porting is all opened, and whole scavenging work completes.The exhaust of the design piston matrix firing chamber here cambered surface (32) of regulating the flow of vital energy, before slightly height a bit, become arc smoothly just to exhaust port (6), 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 (25) of opened precompressed air, it is far from being enough depending that the angle being originally arranged on casing wall regulates the flow of vital energy here alone, and also therefore original two-stroke gasoline engine just can cause the loss of a large amount of new inflammable gass to see that (35) in 8 pages, accompanying drawing locate.To have utilized after the function of new design piston herein, in the time opening precompression suction port (25), 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 (37) that cylinder head cannot process originally, the boss cambered surface that utilization is arranged at cylinder cap front portion pushes away gas to cylinder head position straight, turn back backward cylinder body rear and low part advance, 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, arranging in conjunction with entirety amendment herein, making new inflammable gas form a straight shape pushes ahead, the design here, it is all unresisted smooth and easy shape, more be conducive to outside whole waste gas kickoff mechanisms, ensure that again fresh combustible gas is not running off from relief opening simultaneously.

Newly-designed two stroke engine is for the design of crank bent axle and concrete compression method: the weight of the crank bent axle in two stroke engine is excessive (just takes the engine crank of original happiness 250 discharge capacities to contrast, the weight of the crank of 250 motors originally, twice than motor portion overall weight is also many), use crank bent axle therefore changed the tradition of original engine, use semiaxis (17) work.Take away after the crank bent axle of motor, because motor has not now had the power of being used to, can affect the work of engine compresses, but this engine design is for having A cylinder portion and B cylinder portion to see 1,2 pages, accompanying drawing, the A cylinder outburst acting of motor in the time of work here, descent of piston, is just in time the piston stroking upward of B cylinder, and the gas in cylinder is implemented to compression.B cylinder, in the time of outburst acting, can promote again A cylinder the gas in cylinder is implemented to compression.Between such two cylinder bodies, cooperatively interact, also just well solved the work problem of complete machine.The length of motor has been elongated in the design of this motor, and the height that has reduced motor has reduced center of gravity, is in order to increase the stationarity of vehicle in running at high speed.Newly-designed motor center of gravity is lower, is the safety that ensures Vehicle Driving Cycle, deducts the another parts such as shock absorbing facility and crank bent axle of former motor, the vibration problems while solving engine operation for opposed work.The structure that emphasis overall design is more taken pains in the design of this motor is simpler, and the lighter volume of weight is less, but power is larger.This project usage range is wide, manufactures easy to maintenance and cost is extremely low.2.0 times of the more approaching same discharge capacity four stroke engine power of power of newly-designed two stroke engine.The power of traction and the safety coefficient of travelling can be improved significantly.

The adopted concrete scheme of dealing with problems is:

In order to solve deficiency more than original old-fashioned two-stroke gasoline engine, " environment-friendly and energy-efficient two-stroke opposed type is without crank crank-axle engine ", for the weight that alleviates original motor of a most step, upgrades again and improves original motor.In the time of the structure of designed engines, the working method of motor is changed, retain the normal place of former motor, change deficiency.In the time that reality is implemented, change the historical custom that uses blend gasoline of former history two-stroke gasoline engine, change and be made as the pure gas and oil work by combustion of use, be more conducive to environmental protection low-carbon emission.Change original two stroke engine and utilized the precompressed structure of crankcase, and non-establishing paid cylinder compression, for doing work in the main pressing chamber compression of supply explosive combustion after this cylinder generation pre-compressed gases, change the profile of scavenging way and the piston of original motor, and the profile of cylinder head, new inflammable gas is entered after main pressing chamber, after flinging the dead angle area of waste gas, push ahead straight, be conducive to the loss of emptying waste gas and control live gas, and be more conducive to increase the power of motor and save the energy, changed the lubricating system several times of original motor raising the working life of motor.

Change scavenging way, utilize this cylinder oneself to produce precompressed air, function is done in the outburst of supply firing chamber, is not utilizing crankcase to carry out precompression herein, and half axle box need to not carry out precompression, just filling engine oil, change semiaxis engine oil chamber into and see that in 1 page, accompanying drawing and figure (21), therefore semiaxis is directly in machine oil, to work, make each bearing, connecting rod bearing, little axle bearing has all obtained fabulous lubricating.In 4 pages, accompanying drawing, main is lubrication circumstances and the structure at the very cylinder body position to the present invention's design, do with detailed signal and explanation, the body portion of the cylinder body here, directly be provided with cylinder body portion engine oil chamber (24), and communicating with cylinder block oil lubricating hole (7).Like this, when lubricant oil is by being arranged on the oilhole (7) of cylinder machine (5), directly enter into the inwall of cylinder block, implement lubricated to cylinder block (5) and piston (4) and piston ring (3).Here just can very clearly see by A figure in 4 pages of figure of accompanying drawing and B figure, no matter piston (4) is at top dead center, or all cannot get out of the way cylinder block lubrication hole (7) in lower dead center, be 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.

Being designed to cylinder block and cylinder head is integral type (5), at piston (4) during to top dead center, the firing chamber (2) of the lower camber side of piston and cylinder head composition, and the directly type that is designed to tiltedly at the cylinder head place of firing chamber, approximately 1/13rd place, front top of piston (4) is designed to sharp convex and sees 6 pages, accompanying drawing, and in being provided with upwards by precompression suction port (25) one side pistons the air inlet of the camber cambered surface (31) of regulating the flow of vital energy, being beneficial to new attached pressurized gas enters and directly rushes at after cylinder block (5) 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.This design is main can do fine processing to the waste gas of the dead angle area (37) of former cylinder inner casing postoperculum and get rid of for solving new pre-compressed gases to enter each circulating area after cylinder block (5) smooth and easy, sees 5 pages, accompanying drawing.Change the design of cylinder block integral type, strengthened the sealing effect of cylinder head and cylinder block, also simplified the technique of manufacturing.Between cylinder and body (5) and half axle box, use fixing sieve screw mandrel (22) by cylinder block (5) and half axle box secure bond.

Embodiment:

When the descending combustible gas to new suction of piston (4) is pre-compressed to lower dead center, the inflammable gas of paying compression cylinder block bottom pay pressurized gas air outlet (12) by compressed air channel (10) to inflammable gas suction port (25) to cylinder block (5) in the new inflammable gas of injection.Fresh inflammable gas enters after cylinder block (5), piston starts up to the inflammable gas enforcement compression in cylinder, when piston (4) arrives top dead center, with cylinder cap composition firing chamber (2), the now spark plug sparking compressed combustible gas that ignites, promote descent of piston, motor starts acting.Piston (4) is secure bond with piston guide rod (9), and piston guide rod (9) is connected with the little axle of piston (13).Piston guide rod is connected with connecting rod (14) by the little axle of piston (13).Connecting rod is connected with semiaxis connecting rod stub (15).Semiaxis stub turns axle (27) with semiaxis and is connected, and semiaxis turns axle and is connected with semiaxis (17).Like this, the acting of piston will be turned after the another parts such as axle, semiaxis become vertical motion to rotatablely move by the little axle of piston, connecting rod, semiaxis connecting rod stub, semiaxis, and the machine that is sent is outer and complete the output of engine power.Piston (5) implements exhaust during to lower dead center, enter next working procedure after injecting new inflammable gas.Because two groups of cylinders of motor of design for this reason are in the same horizontal line, A cylinder breaks out after work done like this, descent of piston, and now just in time the piston stroking upward of B cylinder is implemented compression to the inflammable gas in cylinder.Otherwise and, in the time of A cylinder outburst work done, just in time promote again the compression of B cylinder piston stroking upward.Like this utilize the work that matches of two groups of cylinders, also just well solved two groups of cylinders dynamical problem used in the time of precompression.

In " 1 page, accompanying drawing ", first the axle (22) that turns of motor is packed in body (46), can assemble rear inspection turns axle and rotate, then the piston (16) that installs piston gas ring (15) and oil ring (1721) packed in cylinder block (13) and piston be pushed into the bottommost of cylinder block, allow piston guide rod (3) whole Shens from piston guide rod slideway (5) go out, chain bar (20) is being drawn out to the highest position.While now cylinder block (13) being loaded to half position along the fastening sieve screw mandrel of cylinder post (51), the little axle of piston (19) and little axle jump ring are being aimed at and installed to bent axle chain bar (20) and piston guide rod (3), then cylinder body is being pushed into and the junction of turning axle box, the assembling that is not always the case of each group cylinder position, all essentially behind one group of cylinder position checks that whether the rotation situation of bent axle is free but often install.Finally add four-stroke special engine oil.Like this is exactly, very simple.The motor maximum number of revolutions of design, the design maximum number of revolutions of two stroke gasoline engines be per minute one very much/turn.Because diesel engine need to strengthen compression ratio, the centrifugal force of piston also can strengthen thereupon, is equipped with again oil pump work in addition and does.The maximum number of revolutions of two-stroke diesel engine design be per minute be 5,000 points/turn.

Advantage and the Chang Chu of the present invention's design are:

Former two-stroke gasoline engine is because the problem of design at that time, in the time of work because the severe discharge of tail gas causes serious environmental pollution.Original two stroke gasoline engines, because the problem of design at that time, the work component at its main position are to work the in the situation that of very severe, so motor does after a period of time in work, just must there is the phenomenon of crankcase oil seal gas leakage, this is the problem that allows people have a headache most, because the lighter there will be being short of power of motor after the gas leakage of the oil sealing of crankcase, job insecurity, treat that speed treats incessantly, accelerate unable, hair car at a high speed, sudden engine stops burning, and separately also has the situation that the machine oil of gear-box is thinning and increase etc.Now change engine oil more just, and crank shaft oil seal, as changed not in time oil sealing, these feelings can repeat to occur at short notice, and can be to motor cannot normally be worked in the time that gas leakage is serious.Particularly two stroke gasoline engines of multiple casing, because the time of the explosive combustion workmanship between each cylinder body is different, pay the normal work of compression for ensureing crankcase, just must between the crankcase between cylinder and cylinder, be added with oil sealing and intercept, this oil sealing must be located at again the intermediate portion of bent axle.On end, tell, if the gas leakage of the crank shaft oil seal between crankcase and the crankcase of original two stroke gasoline engines, be take apart the engine exactly two stroke gasoline engines of overhaul, particularly multi-cylinder of one handling, also must take the crank of bent axle apart and change the middle oil sealing between bent axle.Like this will be when making to keep in repair elapsed time long, expense is high, and the more important thing is the short and maintenance of interval spreadable life often.Crankcase blow-by also can to make a large amount of fuel wave useless (including gasoline engine oil all), this also directly can cause the wave of the energy useless.These are all also some minor matters, and main is because original two stroke engine, because the problem of design at that time, the main part of motor, is all that work is done under extremely hard conditions, thereby have reached the reduction of beating the working life of motor.Two-stroke gasoline engine originally, because the problem of design at that time, in the time of engine breathing, all can have 25%---40% fresh inflammable gas will be run out of machine and see 8 pages, accompanying drawing (35) outward, and causes the waste of a large amount of energy.Two-stroke gasoline engine originally, because the problem of design at that time, in the time of engine breathing, has and exceedes 30% waste gas and still can remain in machine, so just the work rate that affects motor of great achievement degree very.

The Two stroke engine of this design, remove completely the end solution above-mentioned problem.The more important thing is and saved the energy, protected environment, change into and use the work done of pure gasoline explosive combustion, improved after the conditions of discharge of tail gas, ensured that exhaust emissions is up to standard.And accomplish to accord with and national GB14621---the emission standard of 93 four-stroke machines.Real having reached conforms to " energy-saving and emission-reduction, low-carbon (LC) life, the large situation in the world today of conservation of nature environment.Increase the power of motor.For improving the power stage of motor, when design, improve as possible the revolution of motor, in order to improve the revolution of motor, be designed to the working method of short stroke vat through (but the design of two-stroke diesel engine is not exclusively included).

Newly-designed " environment-friendly and energy-efficient is opposed without crank bent axle two-cycle engine " its tractive force is higher than original two-cycle engine, more higher than four stroke engine, this motor is more suitable for for respectively, greatly, in, the small-sized vehicle taking petrol engine or diesel engine as power is used as traction as the equipment of traction or other power requirement.

The two-cycle engine of this design, just can be diesel engine as long as strengthen compression ratio, because the compression ratio of diesel engine is more much higher than petrolic compression ratio, but after increasing compression ratio, will increase the weight of the work load of crank shaft oil seal, workmanship and the working life of the old-fashioned motor of impact that so just can be serious.The motor of this design does not have crank shaft oil seal and compresses without crankcase, so can be competent at the work of two-stroke diesel engine completely, after strengthening compression ratio, increasing the parts such as oil pump and oil nozzle (spark plug of should taking away), just can be designed to two-stroke diesel engine, and the diesel engine of two strokes is because be that pure air enters in cylinder block, spraying into diesel oil after compression, also without the loss of fuel.Therefore the work that design has improved the attached compression of two stroke engine is done mode, has strengthened the compressed capability of pair compression, so just can effectively increase the output of two-cycle engine power.Therefore the work that design has improved the attached compression of motor is done mode, strengthen the compressed capability of pair compression, so just, can effectively increase the output of two-cycle engine power, make this motor from being originally the 1.6-1.8 times power of same discharge capacity four stroke engine, and more approach the power of 2.0 times, in fact: also because of motor for this reason do not have former four stroke engine "---descending air-breathing---up compression---outburst is done work, and is entering the up scavenging of next program in piston stroking upward scavenging.This sees between whole 720 °, only have 180 ° be to implement acting, other 540 degree are all to pay acting, this plays that code should be called is intermittent type acting, this can reduce the power of motor naturally.And, valve stem, inlet and exhaust valve, valve spring, valve rocker, camshaft, waits the moving of a lot of another parts to do, and all must consume a large amount of power ".Also be because deducted the consumption of the above various pairs of working powers of having told, therefore, the power stage of this motor reality, is to exceed 2.0 times of same discharge capacity four stroke engine.Newly-designed " environment-friendly and energy-efficient is opposed without crank bent axle two stroke engine " its tractive force surely can be higher than original two stroke engine, more higher than four stroke engine, this motor is more suitable for for Aviation Industry and various medium and smallly use as traction as the equipment of traction or other power requirement taking petrol engine or diesel engine as the vehicle of power.

The motor of this design is special in modern Hang Tian, and the middle-size and small-size aircraft of reciprocating engine and designing comprises the use of various military aircrafts and Small Civil machine.Due to motor is adjusted and being improved, make the more powerful of this motor, weight is lighter, and its structure is simpler, in the time that reality is used, also breaks down with regard to more difficult.The weight that has alleviated motor has also just increased the load-carry duty of equal-wattage, is as the criterion with the design that is designed to 1.2 discharge capacity, and only this alleviates one of engine weight, just can increase journey and carry power more than 100 kilograms.If the discharge capacity that is 1.2 by this engine design, can acquire very easily 160---the power of 175 horsepowers, and the service property (quality) of this motor and working life, there is again fabulous guarantee, if motor of its cost is also with regard to hundreds of yuan after batch production.Due to another parts such as the cranks of having taken away again, make the weight of motor lighter, because the weight of two stroke engine crank is originally all very large, with regard to the happy 250 model motor by original, the weight of its crank just has the twice (this is the weight of having removed gearbox place, because the motor that designs is also without gearbox for this reason) of motor must be many fully.Taken away the weight of the motor after crank, can be lighter and handier than original motor, and complete machine weight can be 1/4th of same discharge capacity four stroke engine, are 1/8th left and right of same power four stroke engine.The motor gross weight of 1.2 discharge capacities, also with regard to tens kilograms, can just can withdraw with a hand very easily.This engine design is not only thin but also long in addition, and so just more favourable various SUAVs are the resistance that tablet reduces aircraft flight fuselage design, and is increased in heat dissipation potential air-cooled while flight.I feel the various middle-size and small-size aircraft in modern military unmanned machine, should do fuselage with north steel, this is not completely in order to reduce costs, because north material itself is all the object of insulation, should be that the electric wave of radar transmitting is not reacted, the exhaust emissions of reciprocating engine is minimum again, compare with vortex-spraying type motor with jet engine, just there is no the discharge of temperature-sensitive at all, in addition there is no again flue dust in the pure fuel oil work of use, be exactly in addition carry long-pending can be little, the little target of volume is found yours with regard to little being also just not easy by the other side, and volume is less just flexible, so also will more benefit stealthy.Having in modern military equipment, with regard to by aircraft, what you ran is being all otiose soon, you run also running only guided missile soon, also only try every possible means to allow the other side cannot find you, this is only most important.If design 160---the power of 175 horsepowers, weight very light again itself, the weight of carrying 300 kilograms should be no problem, that is to say the TNT explosive that can carry 300 kilograms, goes to hit its target.But also can be arranged to three groups of motors or five groups of simultaneous firings, and increase the Cheng Zailiang of aircraft, when one group of motor that main is therein breaks down, utilize the cluster engine of its remaining part, play the landing that can ensure safety.Small-sized bomber should be that project organization is as possible simple, and the cost of the manufacturing must be low, if the cost of a small-sized bomber in the time of 10,000 yuan of left and right, which just takes it to make movably guided missile to carry out use, that is to say only to fly out and need not fly back.Because the target at fixing MISSILE LAUNCHING place is very large, that has also just become enemy to find emphatically the target of hitting, and the design of this small-sized aircraft, can take off by special runway completely again, as long as there is the highway on the road surface of expressway or first class just can take off completely, therefore its flexibility is extremely strong, this baby plane can be used to the lorry of Large Box goods, being transported to several kilometers of the distance objectives place to hundreds of rice takes off, its chain of command also can be contained on gas car, convenient, flexible random commander, hits enemy with abrupt effect.
