Abstract
An internal combustion engine comprises a lubrication system having a crankcase lubricant delivery port adapted to deliver lubricant to engine components within a crankcase chamber and a cylinder lubricant delivery port adapted to deliver lubricant to engine components within a cylinder bore. In engines having inclined or horizontal cylinders, a cylinder lubricant delivery port can be formed through an uppermost wall of the cylinder, and lubricant distribution is aided by gravity. A different volume of lubricant may be delivered to the crankcase lubricant delivery port than is delivered to the cylinder delivery port. The present invention has particular advantages for use in two-cycle, direct-injected engines.
