Labyrinth type oil-gas separation chamber with additionally mounted turbine

Abstract

The invention relates to a labyrinth type oil-gas separation chamber with an additionally mounted turbine. The labyrinth type oil-gas separation chamber comprises a labyrinth oil-gas separator, a pressure adjusting valve, a non-woven filter element and the turbine. The pressure adjusting valve is arranged on the wall of the labyrinth type oil-gas separation chamber, and mixed oil mist from a crankcase enters the labyrinth type oil-gas separation chamber through the pressure adjusting valve and a mixed oil mist inlet. The turbine is assembled at a free end of a camshaft, the nonwoven filter element capable of filtering oil and water in mixed gas is arranged in an inlet of the turbine, and an outlet of the turbine is connected with the labyrinth type oil-gas separation chamber through a connector. An indented baffle made of engineering plastics is arranged in the labyrinth type oil-gas separator. The temperature of flowing oil mist in a labyrinth is effectively decreased by rotation of the turbine, flow rate of the oil mist is increased, condensation speed of elaioplast is increased, and pressure at a gas outlet is increased.

Description

technical field [0001] The invention relates to a labyrinth type oil-gas separation chamber, in particular to a labyrinth type oil-gas separation chamber equipped with a turbine. Background technique [0002] With the increasing demand for energy saving and emission reduction, the emission regulations are becoming more and more stringent, and the crankcase forced ventilation system has gradually been adopted in vehicle engines. In the crankcase forced ventilation system, the blow-by gas of the engine piston must be recovered into the intake pipe, which requires that there be no oil droplets in the recovered gas as much as possible. If the oil in the "bypass mixture" cannot be cleaned, it will affect the The combustion of the engine will damage the filter element of the air filter, which will lead to the increase of the PM emission of the engine and the clogging of the air filter. This part of the residual exhaust gas must be quickly discharged from the crankcase to ensure t...
