Abstract

Combustion engine consists of two pistons fitted to a common crankshaft reciprocating in two adjoining cylinders connected at the top to form a semi-spherical combustion chamber. One cylinder has an exhaust port which is uncovered by the corresponding piston in the usual way, and the other piston uncovers first an air inlet port and then air fuel mixture port, arranged in it's corresponding cylinder wall as it descends. Two pumps consisting of cylinder and pistons adjoining the combustion block are driven from the same crankshaft offset 180 deg. and at half the radius. One pump piston delivers air via a heat exchange unit and the other piston pump delivers a fuel air mixture. The pump unit delivery ports contain non return flaps.
