Automobile engine oil and gas separator

Abstract

The invention discloses an automobile engine oil-gas separator, which comprises a lower hollow cavity (1) and an upper casing (2), and the side of the lower hollow cavity (1) is connected with an air intake pipe for entering mixed oil and gas (4), the bottom of the lower cavity (1) is provided with an oil outlet pipe (5), the upper casing (2) is provided with an outlet pipe (6), and the lower cavity (1) ) is provided with a first separation mechanism and a second separation mechanism, the first separation mechanism includes a separation bracket (8) for guiding and a cavity (20) communicated with the intake pipe (4), the cavity The body (20) is located at the upper part of the lower cavity (1), the upper end of the separation bracket (8) is sealed and fixed on the inner wall of the upper part of the cavity (20), and the air inlet pipe (4) and the cavity (20) The outer circumference is connected tangentially, and the invention provides an automobile engine oil-gas separator with high efficiency and good filtering effect.

Description

technical field [0001] The invention relates to an oil-gas separator, in particular to an automobile engine oil-gas separator. 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. To prevent direct entry into the atmosphere and cause air pollution, according to the prior art, an oil-gas separator for automobile diesel engines has been disclosed on the website of the State Intellectual Proper...

[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. To prevent direct entry into the atmosphere and cause air pollution, according to the prior art, an oil-gas separator for automobile diesel engines has been disclosed on the website of the State Intellectual Property Office. Filtration device filtering, low efficiency, poor filtering effect
