Device made up of a cylinder head and its cover, which are mounted on the engine block, for de-oiling of waste gases coming from combustion and compression

摘要

A device comprising a cylinder head and its cover for mounting onto an engine block of an internal combustion engine are disclosed, wherein a passageway arranged in the cylinder head cover ensures the circulation of gases loaded with oil in a chamber which is lined with alternately opposing walls that define baffles, until completely de-oiling, by settling, the gases which arrive on the bottom wall of the cylinder head cover situated downstream from baffles. The settled oil passes through openings of bottom wall and returns towards an oil core of the cylinder head, while the de-oiled gases are routed downstream from an intake valve by a set of ducts. The device makes it possible to completely integrate the circulation, de-oiling and return of the gases to the intake, inside the cylinder head.
