Abstract

L'invention concerne un moteur à combustion interne (1) comportant un carter de cylindres (3) disposé entre une culasse (5) et un bac à huile (2), et comportant un dispositif de ventilation comprenant un séparateur d'huile (6), une cheminée (7) acheminant les gaz de blow-by depuis le carter de cylindres (3) jusque dans le séparateur d'huile (6), un conduit de retour d'huile (8) reliant directement le séparateur d'huile (6) au fond du bac à huile (2), caractérisé en ce que le séparateur d'huile (6) et la culasse (5) ne communiquent pas l'un par rapport à l'autre.

Figure imgaf001
The invention relates to an internal combustion engine (1) comprising a cylinder block (3) arranged between a cylinder head (5) and an oil tank (2), and comprising a ventilation device comprising an oil separator (6). ), a chimney (7) conveying the blow-by gases from the cylinder block (3) into the oil separator (6), an oil return pipe (8) directly connecting the oil separator (6) at the bottom of the oil tank (2), characterized in that the oil separator (6) and the yoke (5) do not communicate with each other.
