BLOW-BY GAS RECIRCULATION STRUCTURE FOR ENGINE

摘要

A blow-by gas reflux structure and an internal combustion engine having the same are provided to make the blow-by gas reflux to an air intake side using a through hole and a connecting hole. A blow-by gas reflux structure comprises a gas-liquid separation part(100), a supporting member(9), and a mounting bolt(10). A fluid part among the blow-by gas is separated by the gas-liquid separation part. The supporting member supports a cam shaft(7) in order to make a cylinder head rotate. The mounting bolt mounts the supporting member on the cylinder head. In the mounting bolt, an axial through hole(10a) is formed. The through hole is connected through the axial direction and connected to the gas-liquid separation part. A connecting hole is formed at the cylinder head.
