ABSTRACT:
A high-efficiency explosion engine has a double-acting central piston mounted on a shaft within a cylinder to form two combustion chambers. Auxilliary pistons mounted on the ends of the shaft control the intake of gases to the combustion chambers. In one embodiment, the auxilliary pistons are mounted axially offset from the piston shaft. In a further embodiment, fuel is provided through the piston shaft into the combustion chambers dependant upon the position of the piston within the cylinder.
