Windage tray

摘要

A windage tray apparatus is provided and is configured to be mountable within a crankcase at least partially defined by an engine block of an internal combustion engine. The crankcase has a first bay and a non-adjacent second bay. The internal combustion engine has a crankshaft rotatably supported within the crankcase. The windage tray includes a tray member and a passage at least partially defined by said tray member and in communication with the first bay and the non-adjacent second bay. The passage is operable to allow gas transfer between the first bay and the non-adjacent second bay to reduce the motoring friction of the internal combustion engine. An internal combustion engine incorporating the disclosed windage tray apparatus is also provided.
