Problems solved by technology

The oil-air separator is indispensable in the forced ventilation device of the crankcase, so the separation efficiency is also crucial, but the existing oil-air separator has the following disadvantages: the oil-air separator arranged on the separator housing often separates The oil and gas at the front and back are mixed together, and the separation effect is poor, resulting in poor oil return and hidden dangers of oil channeling

Abstract

The invention discloses a gas-oil separator and relates to the technical field of automobile engines, solving the problem of poor gas-oil separation efficiency. The gas-oil separator comprises a separator shell, wherein a gas-oil separation cavity is arranged in the separator shell; one end of the gas-oil separation cavity is communicated with a gas-oil air inlet, and the other end of the gas-oil separation cavity is communicated with an air outlet cavity; a cyclone gas-oil separator is arranged in the gas-oil separation cavity; and the upper end of the cyclone gas-oil separator is provided with an air outlet communicated with the air outlet cavity, the side face of the cyclone gas-oil separator is provided with an air inlet, and the lower end of the cyclone gas-oil separator is provided with an oil outlet. The gas-oil separator provided by the invention is applied to various automobiles and acts as a gas-oil separation mechanism of a ventilating device in an engine crankcase.

Description

technical field [0001] The invention relates to the technical field on automobile engines, in particular to an oil-gas separator on the engine. Background technique [0002] In recent years, the global requirements for the automobile industry to solve environmental protection, energy and other issues have become higher and higher, especially the emission problem has received more and more global attention. With the increasingly stringent emission regulations related to automobiles, the oil in the crankcase in the engine The emission problems caused by fog particles and exhaust gas (hydrocarbons) are also getting more and more attention. [0003] At present, in order to reduce the exhaust gas discharged from the engine and reduce the damage to the engine, the crankcase is basically ventilated. The ventilation methods of the crankcase generally include natural ventilation and forced ventilation, but natural ventilation is to ventilate the inside of the box. The gas is vented ...
