ABSTRACT OF THE DISCLOSURE Disclosed herein is a two-cycle internal com- bustion engine including a cylinder having a fuel intake port, an exhaust port, and an inlet port located inter- mediate the intake port and the exhaust port, a piston reciprocably mounted in the cylinder, a crankcase having a drains collecting area, and a conduit means connected in liquid communication with the drains collecting area and with the inlet port, whereby the drains are recycled or re- circulated from the drains collecting area to the cylinder for ultimate combustion therein in response to the cyclical variation of pressure in the crankcase and in the cylinder. In a preferred embodiment, the conduit means includes a first conduit which is connected in liquid communication with the drains collecting area and with an upper bearing rotatably supporting the engine crankshaft and a second conduit which is connected in liquid communi- cation with the upper bearing and with the inlet port such that the recirculating drains contact and lubricate the upper bearing enroute to the cylinder.
