Multi-layer oil-gas separating device for automobile engine

Abstract

The invention provides a multi-layer oil-gas separating device for an automobile engine. The purposes being high in separating efficiency, good in filtering effect and multiple in separating layers are achieved. The multi-layer oil-gas separating device for the automobile engine comprises a cover body, and the cover body comprises a chassis and an upper cover (2) which are detachably connected. The multi-layer oil-gas separating device for the automobile engine is characterized in that the chassis (1) is provided with a first air inlet (3), a first channel (4) is arranged on the portion, corresponding to the first air inlet, of the upper cover (2), and a second channel (5) is arranged on the side face of the first channel (4); the chassis (1) is provided with a first partition plate (9), the cover body is provided with a lower channel (6) and an upper channel (7), the lower channel (6) is located under the first partition plate (9), and the upper channel (7) is located over the first partition plate; and a first column ring (8) is fixedly arranged on the chassis (1).

Description

technical field [0001] The invention relates to the technical field of engine oil-gas separation, in particular to a multi-level oil-gas separation device for automobile engines. Background technique [0002] The oil-air separation device is connected to the engine cylinder head cover, because when the engine starts, the blow-by gas of the cylinder and the oil vapor will generate pressure, which will cause damage to the engine, so it is necessary to use the crankcase oil-air separation device to make it generate negative pressure, because There is a large amount of oil vapor in the gas extracted by the crankcase ventilation valve, so the oil-gas separation device mainly separates the oil vapor into oil and steam, so that the oil is collected in the pan and then flows back to the engine for reuse, and the steam flows to the engine for re-combustion to prevent Directly enter the atmosphere, causing air pollution. The separation device in the prior art is to realize the separat...

[0002] The oil-air separation device is connected to the engine cylinder head cover, because when the engine starts, the blow-by gas of the cylinder and the oil vapor will generate pressure, which will cause damage to the engine, so it is necessary to use the crankcase oil-air separation device to make it generate negative pressure, because There is a large amount of oil vapor in the gas extracted by the crankcase ventilation valve, so the oil-gas separation device mainly separates the oil vapor into oil and steam, so that the oil is collected in the pan and then flows back to the engine for reuse, and the steam flows to the engine for re-combustion to prevent Directly enter the atmosphere, causing air pollution. The separation device in the prior art is to realize the separation of oil and gas by setting simple filter components, and then absorb or eliminate it. The disadvantage of this structure is simple structure, low separation efficiency, poor filtration effect, and separation less layers
