Oil-gas separator of automobile diesel

Abstract

The invention discloses an oil-gas separator of an automobile diesel comprising a lower cavity 1, a filter element 3, an upper air accumulation housing 2 and an upper cover 5, wherein the lower cavity is connected with a mixed gas inlet adapter 11, and the bottom of the lower cavity 1 is provided with an oil outlet 12; the upper air accumulation housing 2 is connected with an outlet adapter 21; the filter element 3 is composed of a filter body 31 and a filter body bracket 32, wherein the filter body 31 surrounds the filter body bracket 32; the axial line of the inner tube wall of the mixed gas inlet adapter 11 is tangent with the circumference of the inner wall of the lower cavity; the upper air accumulation housing 2 is set in a mode that an upper bottle cap cylinder 22 and a lower bottle cap cylinder 23 are staggered and overlapped, and the inner space of the overlapped part is communicated. The invention has the advantages that the oil-gas separator can lower internal pressure of acrank case, recovers engine oil contained in gas emitted out of the crank box; the automobile emission technical standard thereof can reach European IV standard, so that the automobile protects environment, saves more energy as much as possible and is more favourable for alleviating energy shortage and protecting environment.

Description

Technical field: [0001] The invention relates to an oil-gas separator, in particular to an oil-gas separator for automobiles, in particular to an oil-gas separator for diesel engines on automobiles. Background technique: [0002] The automobile industry is an important pillar industry in my country, but energy conservation and environmental protection have become a bottleneck restricting its rapid development. The Chinese government attaches great importance to the environmental protection and energy saving of the automobile industry, and requires the active development of energy-saving and environment-friendly vehicles. Accelerating the upgrading of the automobile industry must take the road of technological innovation, and it must be upgraded many times faster than developed countries. China's auto industry started very late, and the world has been ruined by developed countries. Oil depletion, energy crisis, air pollution, ozone layer destruction, the carrying capacity of...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that after the above-mentioned automobile diesel engine is equipped with a supercharger and an improved fuel injection pump, the pressure inside the crankcase of the diesel engine increases greatly, the engine overheats, and the phenomenon of burning engine oil occurs, and at the same time , the gas discharged from the crankcase contains engine oil, which also pollutes the atmosphere. To provide a method that can properly reduce the internal pressure of the crankcase and recover the engine oil contained in the gas discharged from the crankcase Oil and gas separator for automobile diesel engine
