The casing has an enclosed space for reducing flow rate of the waste gas abruply, an air inlet connected to the vent pipe of cylinder head and an air outlet connected to the air cleaner; the guide pipe has one end connected to the air inlet and the other end as open-mouthed bent; and the oil returning pipeline has two ends connected to the air inlet and the casing cavity separately. The treater is used to recover lubricant oil from waste gas before it flows into the air cleaner for reuse.
Description
The present invention relates to a kind of device that the waste gas of crankshaft box of motorcycle engine is handled.
Motorcycle engine, particularly be widely used in the forced air cooling four stroke engine (as the GY6-125 type) of female motorcycle, because its high compression ratio and the big structural characteristics of heat load, and relatively poor relatively cooling effect (whole motor is enclosed in motorcycle covering component inside, by the fan forced air cooling), the operating temperature of motor higher relatively (temperature at cylinder head spark-plug gasket place reaches about 235 degree).Under this hot environment, the lubricant oil at cylinder head place can aggravate gasification.Gaseous state lubricant oil is carried by crankcase waste gas and enters breathing pipe, arrives air-strainer then.In filter cleaner, because the reduction of temperature can make the gaseous state lubricating oil change into tiny particulate.If the liquid particulates of these lubricant oil enter engine chamber, will participate in burning and generation can influence the carbon granules of motor normal combustion.Existing preventive measure are to be provided with two sponges in order to adsorpting lubrication oil particulate in air-strainer.Simultaneously an oil storing tube is arranged below sponge, be used for storing the lubricant oil that sponge absorption flows down after full.The defective of this measure is, when the lubricant oil in the oil storing tube reaches full packages, requires artificially the pipe close of oil storing tube end is pulled out, drain behind the lubricant oil in the pipe again with pipe close stifled on.Do like this lubricant oil of collection is wasted, and because oil storing tube is positioned at motorcycle covering component inside, be difficult at ordinary times observing, add general Consumer and do not know the effect of oil storing tube and accomplish routine observation and draining the oil, so often behind the lubricant oil full packages of oil storing tube, can not in time lubricant oil be discharged.Will cause following consequence in case this situation occurs: 1, lubricant oil enters the firing chamber by air-strainer, and producing carbon distribution at the spark plug position influences the motor normal combustion, and causes outlet pipe to emit blue smoke; 2, lubricant oil may stop up the Carburetor oilhole by Carburetor the time, makes engine operation undesired; 3, lubricant oil can leak out from the mating face of air-strainer and drip on the motor, influences the motorcycle outward appearance, returns the Consumer and brings inconvenience.
The objective of the invention is the problem that produced at above-mentioned crankshaft box of motorcycle engine oil-containing waste gas and the defective of existing measure, a kind of waste gas treater for crankshaft box of motorcycle engine that can reclaim the lubricant oil in the waste gas before crankcase waste gas enters air-strainer is provided.
The present invention is achieved in that this device is made of housing, guide pipe and oil returning tube, housing has a bigger enclosed space that the waste gas flow velocity is sharply reduced, and be provided with suction port and air outlet, and suction port is connected with the cylinder head breathing pipe, and the air outlet is connected with air-strainer; Guide pipe is arranged at the housing inner chamber, and an end is communicated with suction port, and the other end is uncovered bend pipe, and winding pipe exit is towards airintake direction; The oil returning tube two ends are communicated with suction port and housing inner chamber respectively.Its working procedure is as follows: after the crankcase waste gas that contains gaseous state lubricant oil enters this device from the cylinder head breathing pipe, enter housing inner chamber (solid arrow shown in Figure 1 is represented the gas route, and dotted arrow is represented the lubricant oil route) under the guiding of guide pipe.The effect of guide pipe is to avoid high velocity air to go out the air outlet because of inertia to enter air-strainer.After air-flow entered inner chamber, because temperature reduces, gaseous state lubricant oil can be liquefied as fine particles.Simultaneously, because of airspeed sharply reduces, most lubricant oil particulates can be in the bottom of action of gravity deposit at the housing inner chamber, and flow back to cylinder head by oil returning tube and suction port, thereby play the effect of Oil-gas Separation.The low speed flow that contains micro lubricating fluid grain then enters air-strainer from the air outlet.
For making Oil-gas Separation more thorough, be preferably in the position, air outlet spongy layer is set, in order to adsorb residual lubricant oil particulate.Enter like this in the air-flow of air-strainer and just contained lubricant oil hardly.
For checking using effect of the present invention, the present invention has been carried out comparative trial.At first on automotive engine test bench, contrast with above-mentioned existing structure.Existing structure is the promptly full oil of the oil storing tube on the air-strainer after turning round five hours with 7500 rev/mins, and the position, mating face has oil to ooze out.And also not having oil after seven hours in the oil storing tube on the air-strainer with same rotation speed operation after connecting the present invention, the position, mating face does not have oil yet and oozes out.Carry out the road comparative trial then.Earlier the present invention is contained on No. 1 car, No. 2 cars and No. 3 cars are existing structures.When 800 kilometers of running-in periods, just have oil to occur in the oil storing tube of No. 2 cars and No. 3 cars, and No. 1 car does not have.During to 2000 kilometers, the oil storing tube of No. 2 cars and No. 3 cars is expired and the filter cleaner position has oil to ooze out, and the oil storing tube of No. 1 car does not also have oil to occur.Then the present invention is contained on No. 2 cars, and No. 1 automobile-used existing structure, run 800 kilometers after, full oil of the oil storing tube of No. 1 car and filter cleaner position have oil to ooze out, and the oil storing tube of No. 2 cars does not have oil to occur.
The present invention can not only solve effectively and fail the variety of issue that the crankshaft box of motorcycle engine oil-containing waste gas of fine solution produced for a long time, and simple in structure, and fabricating cost is low.Relative component need not done any change on the motor, can install and use.Simultaneously, the lubricant oil in the crankcase waste gas can also be recycled, and saves lubricant oil.
