Abstract

The invention discloses an internal combustion engine oil and gas separating device. The internal combustion engine oil and gas separating device is characterized in that the internal combustion engine oil and gas separating device comprises a first cavity (10), a second cavity (11) and a third cavity (12) which are longitudinally sequentially formed; the first cavity (10) communicates with the second cavity (11) through a first gas channel (13), and the second cavity (11) communicates with the third cavity (12) through a second gas channel (14); the third cavity (12) communicates with a gas outlet pipe (6); the bottom of the first cavity (10) communicates with an internal combustion engine body (5), and a lower oil baffle plate (4) is arranged between the bottom of the first cavity (10) and the internal combustion engine body (5); and the first gas channel (13) is longitudinally covered with the lower oil baffle plate (4). By adopting the internal combustion engine oil and gas separating device, the speed of oil and gas separating can be increased, and the effect of oil and gas separating can be improved.

Description

technical field [0001] The invention relates to an oil-gas separation device, in particular to a separation device for an internal combustion engine. Background technique [0002] During the working process of the internal combustion engine, the oil is delivered to the moving parts of the internal combustion engine to lubricate and cool down the moving parts to ensure the normal operation of the internal components of the internal combustion engine. During the operation of the internal combustion engine, the oil will gradually evaporate to form an oil-air mixture due to pressure changes, high temperature, heat dissipation, etc. The oil-air mixture produced by pressure and temperature changes directly communicates with the outside world through the breathing valve on the internal combustion engine. The oil consumption is relatively large, which seriously affects the performance and life of the whole machine. In order to improve the performance of the product, an oil-gas sepa...
