ABSTRACT:
A rotary internal combustion engine comprises a pair of rotors having a plurality of vanes that intermesh and are located in a single stationary chamber. A central intake conduit provides fresh air upstream of the intermeshing vanes. The air is compressed into a combustion volume wherein the air stream divides and fuel is injected into each air stream. An ignitor in each combustion volume causes the fuel air mixture to combust and expand against the vanes of the rotors. The spent mixture of each stream exhausts through a separate conduit. A portion of the fresh air is trapped between the vanes of each rotor and therefore bypasses the combustion volume. This fresh air remixes with the burning fuel air mixture to provide a lean burn as the gases expand against the vanes and then exhaust. The intermeshing vanes are sized to provide very close proximity of vane tips to roots without physical contact to thereby provide a substantially sealing engagement without rubbing. Similarly, the vane tips engage chamber walls without contact but with close proximity.
