Abstract: Disclosed herein is an internal combustion engine including a combustion chamber, a fuel source, a starter mechanism, fuel conduit means connected in communication with the fuel source for introducing fuel into the combustion chamber, fuel pumping means connected in communication with the fuel conduit means and operable for pumping fuel through the fuel conduit means, drive means for operating the fuel pumping means, and means for operatively connecting the drive means with the fuel pumping means when the starter mechanism is activated to thereby prime the engine.

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.
