Engine oil and gas separation device

Abstract

The invention provides an engine oil and gas separation device, which achieves the purposes of high separation efficiency, good filtering effect and more separating layers. The engine oil and gas separation device comprises a cover body, wherein the cover body comprises an underframe and an upper cover (2) which are detachably connected. The engine oil and gas separation device is characterized inthat the underframe (1) is provided with a first air inlet (3), the upper cover (2) is provided with a first passage (4) corresponding to the first air inlet in position, the side face of the first passage (4) is provided with a second passage (5), the underframe (1) is provided with a first partition plate (9), the cover body is provided with a lower passage (6) and an upper passage (7), the lower passage (6) is positioned below the first partition plate (9), the upper passage (7) is positioned above the first partition plate, and the underframe (1) is fixedly provided with a first column ring (8).

Description

technical field [0001] The invention relates to the technical field of engine oil-gas separation, in particular to an engine oil-gas separation device. 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 separation of oil and gas by setti...

[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
