Beschreibung
Zusammenfassung:	The invention discloses an air supply device of a crankcase ventilation system. An opening of a rocker arm chamber cavity of a crankcase is sequentially connected with a coarse separation structure of an oil-gas separator and a fine separation structure of the oil-gas separator; the air supplementing device of the crankcase ventilation system comprises an air supplementing pipe, one end of the air supplementing pipe is sequentially communicated with an air inlet pipe and an outlet of an air filter, the other end of the air supplementing pipe is connected with an air supplementing valve, the air supplementing valve is arranged at an outlet of a coarse separation structure, and the air supplementing valve is located in an inlet area of a fine separation structure; according to the air supplementing device of the crankcase ventilation system, high-concentration oil gas or liquid engine oil in the rocker arm chamber cavity is prevented from being in direct contact with the air supplementing valve, the engine oil
