Abstract:
1. An improved internal combustion engine which is comprised of a pressurized air/fuel mixture intake means, an ambient air intake means, a power piston chamber containing a power piston which power piston is connected by conventional means to a rotating crankshaft, which is further comprised of a minimum volume combustion chamber formed in said power piston chamber when said power piston is located at top dead center of said engine's rotation cycle, an ignition source and an exhaust valve wherein said improved internal combustion engine produces one power stroke for each two rotations of said crankshaft in the following manner, a pressurized air and/or air fuel mixture is injected into power piston chamber close to the top of the stroke, wherein the mixture is ignited, the gas is expanded, after the expansion of the combusted air/fuel mixture and expulsion during the “exhaust stroke” in which the power piston displaces the combusted gases being followed by a stroke in which ambient pressure air is drawn into the power piston chamber by movement of the power piston as in a conventionally aspirated engine and that mixture of ambient air and the residual combustion air/fuel mixture after the valve admitting the ambient air is closed is expelled through the exhaust valve, which closes as the power piston approached the top of the cylinder at which point the compressed air fuel mixture is again introduced into the top of the power piston chamber and ignited for the initiation of another “power stroke”.
