Abstract
An internal combustion engine that has a pair of cylinders each having a reciprocating piston connected to a crank shaft by a connecting rod. One of the cylinders is adapted for an air and fuel intake and a compression strokes only, and the other of the cylinders adapted for at least power and exhaust strokes. A conduit exists for transfer of gases from the one into the other cylinder after the compression stroke. The conduit has means for isolating gases in the conduit intermediate the compression and power strokes. Furthermore, the conduit is designed to prevent the transfer of liquefied fuel from the one cylinder to the other.
