06H103495E 06H103495 Oil Separator PCV Valve Assembly for Audi A3 A4 A5 A6 Q5 TT/for Volkswagen 1.8 2.0L

The main component of the axle box ventilation system is the efficient separation of oil in the crankcase gas channeling, and its separation performance has an important impact on the reliability and emissions of the engine. 2, in the normal operation of the engine, there will be a part of the unburned combustible mixture and combustion exhaust gas in the cylinder through three ways into the crankcase: (1) piston ring end clearance, piston ring and cylinder clearance and piston ring and ring groove clearance; (2) Clearance between valve and valve guide; (3) supercharger bearing clearance. 3. These gas channeling will increase the temperature in the crankcase and increase the evaporation of the oil pan oil. Because the lubrication of some parts in the crankcase is splash lubrication, when the oil mist produced by splash lubrication in the crankcase and the oil steam evaporated at high temperature are mixed with the cylinder gas channeling, most of the particle size is less than 1μm of the ultra-fine aerosol, which is the formation process of the oil-gas mixture in the crankcase gas channeling. The role of the oil and gas separator is to effectively separate the oil and gas.
