ABSTRACT:
A two-cycle rotary internal combustion engine of the fuel injection type. A rotor having three radially disposed cylinders in equally spaced angular relation in a circular rim rotates in sealed rotation within a cylindrical stationary outer housing. The respective pistons in the cylinders are connected to the same crank arm of the crankshaft, which is in turn connected, through a planetary gear mechanism, to rotate in the same direction and at a three-to-one ratio of speed to the rotor. The outer housing has two exhaust ports and two fuel injectors in angularly spaced relation to which the cylinders are opened in timed sequence. Fresh air is supplied under pressure into the closed housing in surrounding relation to the cylinders for cooling the cylinders and for preheating scavenging air admitted to the interior of the cylinders through ports therein. Jets of air, provided by a hole in the rim behind each cylinder, serve to assist in combustion of hydrocarbons in the exhaust gases and also dilution of particulates. In a modified embodiment, the crankshaft and rotor rotate reversely and in three-to-one speed ratio with four exhaust ports and four fuel injectors in substantial quadrature relation in the housing. Various forms of cylinder seal rings are disclosed. One embodiment comprises a tapered split ring seated in a tapered groove. In another embodiment of seal ring a plurality of tapered split rings are assembled into a composite close-fitting concentric relation. Other embodiments of seal rings comprise a solid (non-split) ring with associate split rings to seal against the wall of the groove and with the circular housing.
