ABSTRACT:
Several embodiments of crankcase assemblies for internal combustion engines, wherein the crankcase is configured in such a way as to avoid the loss of oil at the pick-up device, even during sudden maneuvering. This is accomplished in such a way so that the oil will not contact the moving components within the crankcase during normal engine operations so as to avoid churning. In addition, the crankcase is configured in such a way as to provide a plurality of air gaps defined by facing surfaces of the crankcase member so as to provide sound deadening and higher strength with a lighter weight material.
