<p>Supercharged internal combustion engine with crankcase ventilation, comprising a first evacuation conduit (46) for evacuating blow-by gas from the engine crankcase (3) to its intake conduit (20) downstream of the throttle (26), and a second evacuation conduit (43) for evacuating blow-by gas from the crankcase to the engine intake conduit (24) on the suction side of the compressor (23). Each evacuation conduit is connected to an individual oil separator (29, 40), a pressure regulator (42, 25) and a non-return valve (44, 47). Each non-return valve is arranged to permit free gas flow in the direction from the crankcase, but to prevent or limit flow in the opposite direction.</p> |
