Active oil-gas separator

Abstract

The invention discloses an active oil-gas separator which comprises a shell. An oil-gas separation mechanism is arranged between the upper middle portion of a center shaft in the shell and the shell,and a driving mechanism used for driving the center shaft to rotate is arranged between the bottom of the center shaft and the shell. An air inlet used for introducing fleeing gas of an internal combustion engine is formed in the top of the shell, a pure gas outlet is formed in the position, at the bottom of the oil-gas separation mechanism, of the side wall of the shell, and an oil return openingused for lubricating oil to flow out is formed in the position, below the driving mechanism, of the side wall of the shell. The oil-gas separation mechanism comprises a separation disc upper end cover, a separation disc lower end cover and all middle separation discs which are connected between the separation disc upper end cover and the separation disc lower end cover and are arranged on the center shaft. The active oil-gas separator begins to work automatically after a motor vehicle is ignited and stops working automatically after the flameout, electric control is not needed in the work process, efficient oil-gas separation can be conducted on engine fleeing gas, losses of lubricating oil are reduced, long-term stable running can be achieved without maintenance, and very high market value is achieved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to the oil-gas separation technology of an internal combustion engine. Background technique [0002] The lower part of the crankcase of the internal combustion engine is provided with an oil pan, and the upper part is provided with an upper cover. During the working process of the internal combustion engine, blow-by gas will be generated in the crankcase. If the blow-by gas is not discharged in the crankcase in time, the pressure of the crankcase will be too high, which will affect the normal operation of the internal combustion engine. [0003] Because the blow-by gas contains oil, colloid and impurities, if it is directly put into the atmosphere, it will cause air pollution and fail to meet the national emission standards; the blow-by gas will cause the lubricating oil of the internal combustion engine to lose oil, resulting in insufficient lubricating oil for the internal combu...

Problems solved by technology

During the working process of the internal combustion engine, blow-by gas will be generated in the crankcase. If the blow-by gas is not discharged in the crankcase in time, the pressure of the crankcase will be too high, which will affect the normal operation of the internal combustion engine.

[0003] Because the blow-by gas contains oil, colloid and impurities, if it is directly put into the atmosphere, it will cause air pollution and fail to meet the national emission standards; the blow-by gas will cause the lubricating oil of the internal combustion engine to lose oil, resulting in insufficient lubricating oil for the internal combustion engine
