Description
Technical field
The present invention relates to engine component more particularly to a kind of oil-gas separating device for engine with exhaust gas strainer.
Background technology
When engine works, some total combustion mixture and exhaust gas are channeled to through piston ring in crankcase, channel to bent axle
Machine oil will be made thinning after gasoline vapour condensation in case, performance depreciation.Contain vapor and sulfur dioxide in exhaust gas, vapor is solidifying
Knot forms foam in machine oil, destroys engine oil supplying, and this phenomenon is particularly acute in winter；Sulfur dioxide meets water and generates sulfurous
Acid, sulfurous acid encounter the oxygen in air and generate sulfuric acid, and the appearance of these acidic materials not only makes machine oil rotten, but also can make zero
Part is corroded.Since combustion mixture and exhaust gas channel in crankcase, the pressure in crankcase will increase, and machine oil can be from bent axle
Oil sealing, crankcase liner etc. are oozed out and are lost in, and the machine oil steam being lost in air can pollute air.To avoid or
It is endangered caused by mitigating above-mentioned phenomenon, is typically equipped with crankcase bleeder on the engine.
Combustion mixture and exhaust gas in crankcase cannot be directly discharged into air by crankcase bleeder, usually be utilized
Gas in the swabbing action suction crankcase of engine aspirating system, and be arranged in connection crankcase and the pipeline of air inlet pipe
Gs-oil separator detaches the oil, the gas that are aspirated out of crankcase, so that the oil stream of liquid is returned crankcase, gaseous aspiration enters
Air inlet pipe can reduce the consumption of machine oil in this way.
Conventionally known engine is typically to use single breathing piece or reed valve type cyclone separator arrangement, in crankcase
Gas mixture out only passes through first separation, and the separating effect of oil gas is bad, and oil consumption is bigger than normal.
