ABSTRACT:
A rotary internal combustion engine includes a housing having a pair of communicating rotor chambers and a pair of parallel axis rotors provided in each chamber. The rotors each have outer gear teeth and an inner chamber having a mixer. A fuel/air mixture introduced into the inner chambers is homogenized by the mixer and the resulting fuel/air mist is introduced into the areas between the outer gear teeth. Rotation of the rotors compresses the fuel/air mist between the outer gear teeth and, following ignition at a point proximate engagement of the teeth, the expanding exhaust gases create a rotational force driving the rotors. The exhaust gases are extracted via ports in the housing position immediately before the inlets for the air/fuel mist. Alternatively, the inner chamber may be used to compress air which is then directed toward a fuel injector nozzle.
