Venting system for engine crank case with dry sump lubrication, employs oil suction pumps capable of sending blow-by gases to inlet manifold

摘要

Suction pumps (5, 6) remove oil from the crank case (2). Their construction permits blow-by gases to be sucked out in addition, through a vent line (13). A further line (not shown) conducts these gases into the engine (1) inlet manifold (18).
