Labyrinth oil and gas separation chamber with turbine installed

Abstract

The invention relates to a labyrinth oil-gas separation chamber equipped with a turbine. The invention includes a labyrinth oil-gas separator, a pressure regulating valve, a non-woven fabric filter core and a turbine. The pressure regulating valve is arranged on the wall of the labyrinth oil-gas separation chamber, and the mixed oil mist from the crankcase enters the labyrinth oil-gas separation chamber through the pressure regulating valve and the mixed oil mist inlet. The turbine is assembled on the free end of the camshaft, and the inlet of the turbine is provided with a non-woven filter element which can filter the water and oil in the mixed gas; the outlet of the turbine is connected with a labyrinth oil-air separator through an interface. A toothed baffle made of engineering plastics is arranged inside the labyrinth oil-gas separator. The rotation of the turbine in the invention effectively reduces the temperature of the flowing oil mist in the labyrinth, increases the flow rate of the oil mist, increases the condensation rate of the oil particles, and increases the pressure of the air outlet.

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...
