Horizontal type oil-gas separator for diesel engine

Abstract

A horizontal oil-gas separator for a diesel engine, which comprises a housing (1) and a filter element (2), the housing (1) is provided with a filter cavity (3) and a buffer cavity (4), the filter cavity (3) It is located on one lateral side of the buffer cavity (4), and the filter cavity (3) communicates with the buffer cavity (4); the lower part of the filter cavity (3) on the housing (1) is provided with an air inlet for mixing ( 5), the air inlet (5) communicates with the filter chamber (3) through the air inlet channel (6); the upper buffer chamber (4) of the housing (1) is provided with an air outlet (7), and the housing (1) An oil return port (8) is provided below the buffer cavity (4); the filter element (2) is located in the filter cavity (3), the filter element (2) is an annular structure, and the filter cavity (3) A regulating valve (9) is arranged on the top of the inner air inlet passage (6), and the outer diameter of the regulating valve (9) is smaller than the inner diameter of the filter element (2) but greater than the inner diameter of the air inlet passage (6), and the regulating valve (9) It is arranged eccentrically with respect to the air intake channel (6); compared with the prior art, the present invention has the characteristics of higher oil-gas separation efficiency and better use stability.

Description

technical field [0001] The invention relates to the technical field of engine oil-gas separation, in particular to a horizontal oil-gas separator for diesel engines. Background technique [0002] The oil-air separator is connected next to the crankcase ventilation valve of the engine, because when the engine is working, the blow-by gas of the cylinder and the oil vapor will generate pressure, which will cause damage to the engine, so it needs to be vacuumed through the crankcase ventilation valve, because There is a large amount of oil vapor in the gas extracted by the crankcase ventilation valve, so the oil-gas separator mainly separates the oil vapor into oil and steam, so that the oil is collected by the pan and flows back to the engine for reuse, and the steam flows to the engine for re-combustion. Prevent direct entry into the atmosphere and cause air pollution. [0003] The horizontal oil-gas separator for diesel engines in the prior art, such as the Chinese invention...
