Background

When the engine works, part of combustible gas mixture and waste gas always flow into the crankcase through the piston ring, the combustible gas mixture flowing into the crankcase is condensed and then drops into the oil pan to deteriorate the engine oil, and if the gas cannot be discharged out of the crankcase in time, the pressure of the oil pan is too high, and the oil seal of the crankshaft is leaked. Currently, international engines (including diesel engines, gasoline engines and other types of internal combustion engines) mainly exhaust gas in a tank through a breather arranged on a crankcase to ensure pressure balance in the crankcase and prevent the exhaust gas from polluting engine oil. However, if the service life of the engine is too long, the blow-by amount of a piston ring is increased, or other components of smoke generated after the engine has a cylinder-pulling and tile-burning fault, the conventional respirator cannot be used for self-judging the air displacement and distinguishing the smoke, so that the engine cannot achieve the self-protection function, and some conventional respirators utilize a filter layer to separate oil and gas, the contact area of the filter layer and the gas is small, oil accumulated on the filter layer is dripped and discharged by gravity, the discharge speed is low, and the continuous adsorption of the filter layer on the oil is influenced.
