Abstract

An oil-gas separator comprises a shell, an S-shaped mixed gas channel, a maze structure and a cyclone structure. The shell is mounted on a cylinder head cover and internally provided with the S-shaped mixed gas channel. The maze structure and the cyclone structure are arranged in the shell. The technical scheme includes that a mixed gas inlet of the mixed gas channel is formed in the bottom of one end of the shell, a retainer platform structure is arranged at the mixed gas inlet, the maze structure is arranged between the mixed gas inlet and the mixed gas channel, the cyclone structure is arranged at the tail of the mixed gas channel, oil return control valves are arranged at the bottoms of the mixed gas channel and the cyclone structure, and a gas exhaust end of the cyclone structure is provided with a one-way valve and a PCV (positive crankcase ventilation) valve. In this way, the problems of the conventional oil-gas separator such as poor separating effect, high production cost, low separating efficiency and complicated structure are thoroughly solved.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to an engine component, in particular to a multifunctional, integrated and high-efficiency oil-gas separator. Background technique [0002] At present, in the automobile manufacturing, internal combustion engine and other mechanical industries, the oil-gas separator is mainly used to separate the oil from the oil-air mixture in the crankcase of the internal combustion engine, so as to reduce oil consumption and environmental pollution. More and more stringent, low-efficiency oil-gas separator with a single structure can no longer meet the requirements. The separated engine oil returns to the oil pan mainly through the following methods: 1. Directly drips into the crankcase through the oil return hole and then returns to the oil pan, but the mixed gas in the crankcase will enter the oil-gas separator through the oil return hole, Thus affecting the separation efficiency; 2....
