ABSTRACT:
Disclosed herein is a rotary internal combustion engine including a rotor mounted for rotation in a rotor chamber or cavity and having a plurality of apex portions which cooperate with the peripheral wall of the rotor cavity to form a plurality of working or rotating chambers which vary in volume during successive intake, compression, expansion and exhaust phases of the engine cycle, a main fuel inlet communicating with the rotor cavity and communicating successively with each of the rotating chambers to permit intake of fuel for subsequent compression and ignition, a port located to communicate with rotor cavity at an area where a low pressure condition exists during the engine cycle, and a primer valve connected in communication with the port for selectively pumping a quantity of primer fuel directly into the rotor cavity independently of engine operation and thereby facilitating starting of the engine.
