Embodiment:

The concrete enforcement of the utility model two stroke engine energy-conserving and environment-protective: the loss of the combustible gas of the original two stroke engine 25%--40% that utilized newly-designed port configurations to deduct, saves the energy.Use is deposited fuel oil service and has been stopped the severe discharge of original two stroke engine, echos the requirement of country's discharge, has accomplished environmental protection.The concrete enforcement of motor complete machine work: engine design has cylinder cap, cylinder body, crankcase portion.Cylinder cap: cylinder head (1) and piston (43).Spark plug (43) is lighted a fire, and it is descending that the inflammable gas that ignites (55) promotes piston (16) afterwards.Cylinder body: when piston (16) is descending, in cylinder block (13), piston (16) is directly promoted descending after combustion gas outburst, when piston (16) is descending, precompression is implemented to the inflammable gas of precompression chamber (77), then supply main pressing chamber, compression and combustion outburst is done manual work again.Lubricating cylinders is specifically implemented: be provided with annular lubricant road (52) and lubrication hole (53) at cylinder body, lubricant oil enters into (13) in cylinder by lubrication hole, implements lubrication to piston (16), piston ring (15), cylinder inner wall.Promote piston (16) after inflammable gas explosive combustion descending, when piston (16) is descending, send workmanship to crankcase portion by piston guide rod (3).Crankcase portion: bent axle accepts after longitudinal direction that connecting rod (20) sent by piston guide rod (3) does manual work, rotates acting and outside the power stage machine that produces being converted to by bent axle (22).The concrete enforcement of the machine lubrication: crankcase is not carrying out precompression, changes and establishes engine oil chamber (47) filling engine oil, in crankcase, lubricant oil directly implements lubrication to each position of bent axle.The type of machine is established according to the motor of design, this engine lubrication system can directly fly low-priced formula lubrication to the another parts in each position of cylinder block (13) piston, or utilizes oil pump (68) machine oil pipeline (69) to implement the lubricating system of lubrication.When utilizing oil pump (68) to lubricate, machine oil arrives cylinder body portion by oil pump (68) machine oil pipeline (69), and this is exactly separated with cylinder block piston portion by gear-box to lubricate.The another parts such as crankshaft gear lubricate at machine oil Indoor Natural, and the another parts such as cylinder block (13) and piston (16) piston ring (15) are by oil filter (64), oil pump (68) machine oil pipeline (69) is utilized to implement lubrication.The design of the third lubricating system, is the connecting tube (63) establishing the outer lubricating oil tank of junctor, and uses original oil pump instead two-stroke oil pump, lubricate separately cylinder body.Because can become muddy after the lubricant oil in engine oil chamber uses a period of time, and the another parts such as cylinder block (16) and piston (13) piston ring (15), be working life and the service behaviour that very clean machine oil must be needed enough can to ensure it, this design is ensure that cylinder block and piston ring place lubricant oil clean.This design of lubricating respectively ensure that lubrication effect and the working life of cylinder body.The lubrication of present four stroke engine cylinder block (13) piston (16) piston ring (15), all utilize bent axle, lubrication implemented by the lubricant oil of gear-box, lubricant oil muddiness can affect lubrication effect and the working life of cylinder block piston ring afterwards naturally, therefore the working life of the two stroke engine of the design, it is working life of being longer than present four-stroke motor, the design of this motor utilizes cylinder block seat (62) to be separated with crank teeth roller box by the pressing chamber sending out ground machine in addition, ensure that piston ring and cylinder matching gap excessive time, pressurized gas and the harmful substance after breaking out can not enter into bent axle, gear-box, ensure that the clean of lubricant oil, extend the working life of lubricant oil, also be save the energy simultaneously.

This motor is about the specific design of electrospray and enforcement, this motor advocates to be implemented on the larger motor of discharge capacity for electrospray, here main or because of electron spraying system cost is still higher, if be arranged at the motor of small displacement, its cost is more taller than motor possibly, such Consumer can not acknowledge, say be arranged at small displacement engine time each side effect also can not be too obvious.For the enforcement of the electrospray compared with large-duty engine, the design of this motor advocates to implement in the front portion of precompressed inflammable gas suction port (8), do not advocate that design is at in-cylinder direct injection, because the working method of in-cylinder direct injection, can, because of the effect of atomization not as cylinder sprays, PM value after burning, be made to increase several times outward.

This motor accomplishes as possible that when designing and specifically implement structure is simple, and we know, any one equipment, and another parts are various, and its working resistance will be larger.Another parts are various, operationally also more easily break down, and another parts are various, its manufacturing and the cost of maintenance also higher, consuming time also longer, another parts are various, and its larger weight of volume will be heavier.Therefore the design of this motor, accomplishes that structure is simple as possible, economical and practical durable.

The concrete assembling method of this motor:

According to display in " 1 page, accompanying drawing ", the concrete assembling mode of this motor and step are: first load in body (46) by the bent axle (22) of motor, assemble rear inspection bent axle can rotate, then the piston (16) installing piston gas ring (15) and oil ring (17,21) to be loaded in cylinder block (13) and piston to be pushed into the bottommost of cylinder block, allow piston guide rod (3) whole Shen from piston guide rod slideway (5) go out, bent axle chain bar (20) is being drawn out to the highest position.When now cylinder block (13) being loaded to half position along the fastening sieve screw mandrel (51) of cylinder post, then cylinder body is being pushed into the junction with crankcase being aimed at piston guide rod (3) by bent axle chain bar (20) and install the little axle of piston (19), first-class cylinder head (1) finally uses the fastening nut of cylinder post (50) to be tightened.Each group of cylinder position is not always the case assembling, but all must check the rotation situation of bent axle after often installing one group of cylinder position.Finally add four-stroke special engine oil.Like this is exactly, very simply.The motor maximum number of revolutions of design, the revolution of two stroke gasoline engines is 10,000 turns per minute.Because diesel engine needs to strengthen compression ratio, the centrifugal force of piston also can strengthen thereupon, in addition the another parts that do of organic oil pump work again.It is 5,000 that the maximum number of revolutions of two-stroke diesel engine is designed to per minute---6,000 turns.

Advantage and the Chang Chu of the utility model design are:

Two-stroke gasoline engine originally causes serious environmental pollution when work is done because of the severe smoke evacuation of tail gas, and this invention " environment-friendly and energy-efficient two stroke engine " has accomplished that when work is done tail gas must not be discharged fume.Two, original two stroke gasoline engines, because the work component at its groundwork position work when very severe, so motor is after work does a period of time, just must there is the phenomenon that crankcase oil seal leaks gas, this is the problem allowing people have a headache most, because the lighter there will be being short of power of motor after the oil sealing gas leakage of crankcase, job insecurity, treat that speed is treated incessantly, accelerate unable, high speed hair car, motor such as to stop burning suddenly at the fault, and another also have the machine oil of gear-box thinning and situation about increasing etc.Now just must change machine oil and oil sealing, as changed oil sealing not in time, these feelings can be raw from recurrence at short notice, and cannot normally can work to making motor when leaking gas serious.Particularly two stroke gasoline engines of multiple casing, because the difference of the time of the explosive combustion workmanship in each cylinder body, for ensureing crankcase precompressed normal work, just must add oil sealing between the crankcase between cylinder and cylinder and intercept, this oil sealing must be located at again the intermediate portion of bent axle.End told, if the crankcase of original two-stroke gasoline engine and crank shaft oil seal gas leakage, be one handling take apart the engine two stroke gasoline engines of overhaul, particularly multi-cylinder exactly when keeping in repair, the crank also must taking bent axle apart changes the oil sealing in the middle of bent axle.So just, can be long to the time-consuming of maintenance, costly, and the more important thing is the interval spreadable life short and keep in repair often.Crankcase blow-by also can to making a large amount of fuel waves useless (comprising gasoline engine oil all), and this wave also directly causing the energy gives up.Give up for reducing the wave of the energy, when the ventilation of designed engines, make fresh gas entering after in cylinder as possible, pushing ahead (see 7 pages, accompanying drawing) of comprehensive synchronous parallel, the loss wave of the inflammable gas that the minimizing so just can done the best is new is useless.In addition, newly establish the firing chamber (74) at the relief opening of machine (14) place and piston concave arc place to synthesize smooth and easy shape, solve piston when original two-cycle engine is vented and will cause venting Resistance (58) lower than relief opening.The space of crankcase is excessive, also to making precompressed underpressure, particularly when crankcase oil seal leaks gas, all to the power wretched insufficiency making motor, can change and be set to this cylinder oneself generation precompression, effectively add precompressed ability.The special machine oil pump of former two stroke gasoline engines of newly having established " the environment-friendly and energy-efficient two stroke engine " of machine meter to take away, crankcase oil seal, oil sealing in the middle of the bent axle of multicylinder engine, decreases component.After changing this cylinder of cylinder block generation pre-compressed gases into, compressed capability is strong, and air feed is sufficient.The phenomenon that when motor work is done and Du has determined, deflation gas leakage and piston valve type engine and carburetor are regurgitated, adds the power of motor, saves the energy.But in order to the power of stronger increase motor, also to improving the revolution of motor, for improving the revolution of motor, being designed to the working method of short stroke vat through (but the design of two-stroke diesel engine is not included).Change into and use the work done of pure gasoline explosive combustion, the severe exhaust emissions of original two stroke engine is improved, ensure that exhaust emissions is up to standard.And accomplish to pay and national GB14621---the emission standard of 93 four-stroke machines.The large situation in the world today that real reaching conforms to " energy-saving and emission-reduction, low-carbon (LC) is lived, conservation of nature environment, ".

This motor is because decreasing part component, engine weight is lighter, manufacturing cost is lower than former two stroke gasoline engines, more lower than four-stroke gasoline engine, its tractive force is higher than original two-cycle engine, more higher than four stroke engine, reach 2 times that even can exceed original four stroke engine.Be applicable to each large, medium and small type to use as traction and other power traction with the vehicle that petrol engine or diesel engine are power.

The two-cycle engine of this design, as long as strengthening compression ratio is just diesel engine, because the compression ratio of diesel engine is more much higher than petrolic compression ratio, but the work load of crank shaft oil seal will be increased the weight of after increasing compression ratio, so just, the workmanship affecting motor that can be serious and working life, motor of this design is without crank shaft oil seal and precompressed without crankcase, so the work of two-stroke diesel engine can be competent at completely, the parts such as oil pump and oil nozzle (spark plug of should taking away) are being increased after strengthening compression ratio, just two-stroke diesel engine can be designed to, and the diesel engine of two strokes is because be that pure air enters in cylinder block, then strengthen diesel oil spraying into mist, this because of fuel oil be entered by another kind of channel, also without the loss of fuel.Therefore design the work having improved the attached compression of motor and do mode, improve the condition of scavenging, strengthen precompressed compressed capability, so just effectively can increase the output of two stroke engine power, and more mainly also improve the severe discharge of two stroke engine simultaneously.

Therefore design and improved the precompressed work of motor and do mode, strengthen precompressed compressed capability, improve the physical arrangement at motor gas port place, strengthen the ability of scavenging, so just, the output of two-cycle engine power effectively can be increased, make this motor from the 1.6-1.8 times power being originally same discharge capacity four stroke engine, and closer to even exceeding the power of same discharge capacity four stroke engine 2.0 times, in fact: also because of the work journey system of motor for this reason do not have former four stroke engine "---descending air-breathing---up compression---outburst is done work in piston stroking upward scavenging, entering the up scavenging of next program.This sees between whole 720 °, only have 180 ° be in enforcement acting, other 540 degree are all paying acting, and this plays most code should be called it is that intermittent type does work, and this can reduce the power of motor naturally.And, valve stem, inlet and exhaust valve, valve spring, valve rocker, camshaft, waits a lot of the dynamic of another parts to do, all must consume a large amount of power ".Also be because deducted the consumption of the above various pairs of working powers told, therefore, the power stage of this motor reality is to exceed 2.0 times of same discharge capacity four stroke engine during real work.Its weight is for same discharge capacity four stroke engine 2/3---between 1/2.Newly-designed " environment-friendly and energy-efficient two-cycle engine " its tractive force is higher than original two stroke engine, more higher than four stroke engine, this motor is more suitable for using as traction as the equipment of traction or other power requirement with the vehicle that petrol engine or diesel engine are power for each large, medium and small type.

Why cylinder, piston, piston ring place are designed to the summary of three kinds of lubricating systems about this project:

In order to ensure this project implementation, cylinder body portion is designed with to the mode of three kinds of lubrications in this project.The lubricating system of the first design is because the design of the machine is not utilizing crankcase precompression, just change crankcase into engine oil chamber filling engine oil, because crank directly works in lubricant oil, make each crankshaft bearing, connecting rod bearing, little axle bearing is obtained for fabulous lubrication.The lubrication of cylinder, piston, piston ring leans on the knockout press of crank to be thrown away by machine oil to do splash lubrication, and fly low-priced machine oil by behind splash lubrication passage arrival left and right oil chamber, entered in cylinder block by oilhole and implement lubrication, this lubricating system is really simple.But when considering engine operation, combustible gas is compressed very large of the impact force after outburst, inferior part of the cylinder block may be entered through piston ring, particularly motor in use for some time, this phenomenon inherently occurs, the situation that this phenomenon just can cause oilhole to regurgitate occurs, and affects the lubrication effect at cylinder, piston, piston ring place.So just machine second is just established to overlap lubricating system, in body, establish oil pump, machine oil pipeline to cylinder, piston, piston ring implements lubrication, like this because oil pump has certain pressure when supplying lubricating oil, oilhole place just can not occur having the situation of regurgitating, for ensureing lubrication effect herein, and the front end of machine oil fuel supply line adds oil filter (64) before oil pump, too much machine oil is by piston lubrication back oil road (6), and engine oil chamber is got back in piston lubrication back oil road hole (65).3rd cover lubrication strategies design considers: cylinder, piston, piston ring are in all motors, belong to the most accurate place, and be also the maximum place of the work amount of doing, two stroke engine is when normally working, and piston, piston ring are per minute all will come and go more than 3000---5000 time.The effect of machine oil is not only again lubrication, the effect that its also has sealing, heat radiation simultaneously and cleans.Namely have the effect of cleaning make between long after, it is just bound to become muddy rotten, although be provided with oil filter herein, but the machine oil that long-term use is such, inherently affect cylinder, piston, working life of piston ring, consider that original two stroke engine uses the work of two-stroke oil pump, cylinder, piston, piston ring place is forever all in the work of use new oil, this is also some advantages of original two stroke engine dimension one, but shortcoming uses miscella work exactly, here we just inherit the advantage of its dimension one, its shortcoming we just do not wanting it drawing.Like this, at machine peripheral hardware sump, use the two-stroke lubricating oils of high-quality, specially lubrication is implemented to cylinder, piston, piston ring, the new high-quality lubricant oil of so eternal use implements lubrication to cylinder, piston, piston ring, just just can improve the working life of cylinder, piston, piston ring greatly.Because the oil pump fuel delivery of two stroke engine is very little very little, and its charge oil pressure is also large than the pressure of four-stroke machine oil pump, so just piston lubrication back oil road hole (65) place can be shut, allow and compress into cylinder with the machine oil of pressure by oil hole, gas after so not only can stoping outburst is regurgitated through piston ring, also just more strengthen cylinder simultaneously, piston, the lubrication effect at piston ring place, also improve cylinder with regard to more effective simultaneously, piston, the working life of piston ring, if be afraid of that the pressure of machine oil is excessive to meet accident, can to install safety valve additional just passable at piston lubrication back oil road hole (65) place again.In a motor, the working life of cylinder, piston, piston ring is the shortest, and this is also news from nowhere.

In fact, this project is designed with three kinds of lubrication strategies, also be use pure fuel oil work to do because improved by two stroke engine, also beyond example, the design at other place is all no problem, also be lubrication enforcement be again compare key aspect, in order to this object implementation success, in order to the working life of more effective raising motor, so devise multiple lubrication strategies for reference when implementing.
