Abstract

A lubrication system for an in-line engine which has a piston symmetry plane that is tilted relative to a vertical plane is provided with an oil pan and windage tray that facilitates the transfer of oil from a rotating crankshaft to the oil pan without excessive aeration. In addition, it facilitates the removal of entrained air from liquid oil as it passes from the crankshaft to a pool of oil collected in an oil pan. A windage tray is provided with a louver structure and a louver opening structure that assists this passage of oil droplets without undue aeration being caused.
