ABSTRACT:
An improved two stroke, reciprocating, internal combustion engine, with multiple cylinders, each closed by a cylinder head and containing a power piston which is connected to a power output shaft. Each cylinder has means for the intake of working fluid and a cooler for the compressed air. It also contains a displacer that moves between the cylinder head and the power piston. This displacer contains one way flow valving, a means for the exhausting of the working fluid from the cylinder, a movable alternating flow heat exchanger used as a regenerator, a heat shield, and a means to bypass the regenerator. The linkage from the power output shaft to move the displacer contains a spring and damper arrangement that allows the compression and expansion ratios to be varied.
