ABSTRACT:
The present invention is an improved drive train which includes an engine having at least one power cylinder with a power piston mounted for reciprocating motion therein. The power piston is connected to a crank shaft in the usual manner for translation of the reciprocating motion of the power piston into rotation of the crankshaft, which in turn, is transmitted in the conventional manner to the drive wheels of the vehicle. Provision is made for the feed of fuel into a combustion chamber located within the power cylinder at one side of the power piston. Intake and exhaust valves, in fluid communication with the combustion chamber serve, respectively, to allow intake of air during an intake stroke of the power piston and exhaust of combustion products during an exhaust stroke of the power piston. A floating piston at least partially closes the combustion chamber opposite the power piston and is mounted for reciprocating motion relative to the combustion chamber. The reciprocating motion of the floating piston includes a pressure relieving stroke in which the floating piston moves away from the combustion chamber responsive to a predetermined pressure being produced within the combustion chamber by combustion, to reduce the peak combustion pressure.
