ABSTRACT:
An internal reciprocating engine effective to operate at one engine cycle per revolution is provided with a differential stroke piston having an inner piston part, for sealing the cylinder, operating at a cycle different from its corresponding outer piston part, for transmitting power to and from the engine shaft, and a differential stroke actuating means for operating the inner and outer piston parts in the same and the opposite directions within the cylinder and to provide differential stroke periods and/or stroke lengths for the inner piston part cycle.
