Abstract
Disclosed herein is a two-cycle internal combustion engine including a cylinder having a fuel intake port, an exhaust port, and an inlet port located intermediate 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 recirculated 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 communication with the upper bearing and with the inlet port such that the recirculating drains contact and lubricate the upper bearing enroute to the cylinder.
