タ。A fresh air introduction passage that sends fresh air for ventilation into the engine crank chamber is branched from upstream of the throttle valve in the intake passage, and an oil separator is installed in this fresh air introduction passage to separate oil when blow-by gas flows back. An oil separation chamber is provided between the partition plates that form a curved flow path, a drop hole is provided in the bottom plate of this oil separation chamber to return the condensed oil, and a check valve that closes when blow-by backflow occurs is installed in this drop hole. Characteristic engine oil separator.
