Abstract
A supercharged internal combustion engine with crankcase ventilation, comprising a first evacuation channel for evacuating blow-by gas from the engine crankcase to its intake channel downstream of the throttle, and a second evacuation channel for evacuating blow-by gas from the crankcase to the engine intake channel on the suction side of the compressor. Each evacuation channel is connected to an individual oil separator, a pressure regulator and a non-return valve. Each non-return valve permits free gas flow in the direction from the crankcase, but prevents or limits flow in the opposite direction.
