Oil-gas separator of supercharged engine

Abstract

The invention discloses an oil-gas separator of a supercharged engine, and the oil-gas separator comprises a cavity, a gas inlet, a gas outlet and an oil return port, wherein inside of the cavity is provided with an oil-gas separation mechanism, the gas inlet is arranged on the cavity and used for allowing oil gas inside a crankshaft box to enter the cavity, the gas outlet is arranged on the cavity and used for allowing the separated gas to flow out of the cavity, the oil return port is arranged on the cavity and used for returning the separated engine oil to an oil bottom shell, and the oil-gas separation mechanism comprises at least one arc baffle plate which is arranged along the height direction of the cavity. The oil-gas separator can effectively improve the oil-gas separation efficiency and guarantee the returning smoothness of the separated oil. The oil-gas separator is applicable to ventilation systems of different supercharged engine crankshaft boxes.

Description

technical field [0001] The invention belongs to the field of automobiles, and relates to a vehicle engine oil-gas separator, in particular to a supercharged engine oil-gas separator. Background technique [0002] As vehicles have become an important means of transportation in people's lives, various performances of vehicles have also received more and more attention. Among them, various factors affecting engine emission standards have been paid more and more attention by vehicle manufacturers. As the heart part of the vehicle, the performance of the engine directly determines the performance of the vehicle, and the engine mainly relies on the contraction of the piston to work, but because there is a gap at the connection of the piston, the high-pressure mixture of oil, gas and exhaust gas will flow out from the gap of the piston Into the crankcase, once it encounters high temperature and high pressure, an explosion may occur, seriously endangering the safety of the vehicle ...

AI Technical Summary

Problems solved by technology

Therefore, the performance of the supercharged engine's oil-air separator is an important factor affecting engine performance, and poor oil-air separation efficiency will directly affect engine emissions

At present, the traditional oil-gas separator is bulky and difficult to assemble and arrange. It is generally equipped with a filter element structure, which has the defect of poor separation effect. At the same time, the filter element needs to be replaced regularly, resulting in high maintenance costs.
