Abstract
In a crankcase venting system for an internal combustion engine having an engine intake duct including a throttle valve, a partial load venting line extending from the engine to the intake duct downstream of the throttle valve and including a vent line throttle and a full load venting line connected to the engine and leading to the intake duct upstream of the throttle valve, an aspiration line extends between the intake duct upstream of the throttle valve and the partial load venting line for controlling the vacuum generated in the partial load venting line.
