An improved, reciprocating internal combustion engine is disclosed herein. This engine consists of multiple cylinders, each closed by a cylinder head and containing a piston which is connected to a power output shaft. Each cylinder has means for the intake and exhaust of working fluid. It also contains a movable, thermal regenerator, an alternating flow heat exchanger, and means to move this regenerator. Finally, means are provided for the introduction of fuel into the cylinder. The regenerated, internal combustion, reciprocating engine and several variations on it disclosed herein are substantially different from prior art and provide critical improvements over that prior art. These improvements include different operating processes－especially an improved heating stroke, the use of unequal effective compression and expansion ratios, non direct fuel injection, and others.

An internal combustion, reciprocating, regenerated engine having a number of similar working units, each working unit comprising: a) a cylinder, closed at one end by a cylinder head and containing a movable piston which moves in a reciprocating manner and is connected to a power output shaft; b) intake means for permitting the flow of fresh working fluid into said cylinder during a predetermined time during each operating cycle; c) exhaust means to permit the flow of exhaust fluid from said cylinder during a second predetermined time during each operating cycle; d) a thermal regenerator located within said cylinder and between said piston and said cylinder head, said regenerator being an alternating flow heat exchanger which can be moved between said piston and said cylinder head; the movement of said regenerator including a regenerative heating stroke which begins during the last quarter of said piston\s compression stroke and ends after expansion has begun and during the first quarter of said piston\s expansion stroke, said regenerative heating stroke also being of sufficient speed and timing so as to maintain, to the greatest extent possible, a flow of working fluid out of said regenerator, through said regenerator\s hot surface and into the hot volume, throughout said regenerative heating stroke; e) means for moving said regenerator during additional predetermined times during the engine\s operating cycle; and f) means for introducing fuel into said cylinder.
