Claims

[Scope of utility model registration request]

An oil separator chamber is provided inside the cylinder head cover that is attached to the upper surface of the cylinder head, and is surrounded by the inner surface of the cylinder head cover and a bottom plate that is placed facing the inner surface at an appropriate distance from the inner surface, and has an oil separator therein. The engine proby gas reducing device is configured to form a proby gas and return the proby gas to the intake system through the oil separator chamber and at the same time introduce fresh air into the crankcase, facing the oil separator chamber of the bottom plate. A recess bulging downward from the bottom plate is formed at a suitable location, and within the recess, the oil separator chamber is divided into two chambers, a first oil separator compartment and a second oil separator compartment, on the inner surface of the cylinder head cover. The lower ends of the partition walls thus formed are pushed in as appropriate to separate the first oil separator compartment and the second oil separator compartment within the recess and at a position below the bottom surface of the bottom plate, between the bottom surface of the recess and the partition wall. While communicating with each other via a communication path formed between the lower end surface,
A proby gas outlet communicating with the intake passage is formed in one of the first oil separator compartment and the second oil separator compartment, and a fresh air inlet communicating with the proby gas inlet in the intake passage is formed in the other at a position upstream of the proby gas inlet. Proby gas reduction device for engines.
