Engine blowby gas processing system

摘要

A blowby gas processing system includes a breather tube extended from a breather port of an engine and connected to a connecting tube. A breather tube inside which an intake passage connecting a carburetor and an air cleaner is formed and an expanded part provided with a gas-liquid separating chamber adjacent to the intake passage are provided. An entrance joint connecting a lower part of the gas-liquid separating chamber to the breather tube is integrated on one side of the connecting tube and a blowby gas exit communicating the upside of the gas-liquid separating chamber with the intake passage is provided in a partition between the gas-liquid separating chamber and the intake passage. The system is a low cost system having a simplified design enabling oil to be separated from blowby gas without having to include a special oil separator tank before the breather tube.
