ABSTRACT:
An internal combustion engine comprises a housing having two cylinders formed therein, a combustion chamber between the two cylinders, and two crankcases. The cylinders are angularly disposed with respect to one another in a V shape with the combustion chamber being located at the apex of the V-shaped configuration. The crankcases are located at the opposite ends of the V-shaped configuration. Pistons are slidably mounted within each of the cylinders for reciprocating movement toward and away from the combustion chambers. The pistons are operatively connected to the crankshafts. One of the cylinders has inlet ports and the other cylinder has exhaust ports and inlet ports therein. During the scavenging portion of the cycle, the exhaust ports and the inlet ports are all opened. The two sets of inlet ports serve to scavenge the previously burned gases from the combustion chamber and also serve to charge the cylinder for the next cycle. Fuel can be admitted through both sets of inlet ports or through either set for gasoline operation. When fuel is admitted only through the inlet ports farthest from the exhaust ports, loss of fuel out the exhaust ports would be substantially reduced during scavenging. Fuel discharge out the exhaust ports would not be prevalent for diesel units.
