ABSTRACT:
An internal combustion engine includes a power cylinder, a power piston reciprocating therein and an auxiliary piston reciprocating within an auxiliary cylinder. Passages connect the upper end of the auxiliary cylinder to a combustion chamber and a source of air. Rotating valves or conventional reciprocating valves control the intake of an air/fuel mixture into the supercharging cylinder, transfer the mixture to the main or power cylinder and exhaust combusted gases from the main cylinder. An expansion chamber is placed in communication with the power cylinder at the beginning of the power stroke to permit an overcharge of air/fuel mixture to be transferred to the combustion chamber.
