ABSTRACT:
The system and method of this invention is directed to effecting combustion of fuel in a rotary piston, internal combustion engine having a housing defining a trochoidal-shaped, multi-lobe cavity in which a rotor is mounted for planetary rotation and defines with the housing working chambers that successively expand and contract in volumetric size as the rotor orbits within the housing cavity. The system and method comprises a precombustion chamber which communicates with successive working chambers through an outlet port. When the outlet port is open to the working chamber at approximately the initiation of the expansion cycle of the working chamber, all the fuel for a particular engine operating condition of speed and load is mixed in the precombustion chamber with a relatively small quantity of air at a pressure substantially greater than the pressure in the working chamber to thereby cause ignition and flash of the fuel into the working chamber. Complete combustion of the fuel rich mixture flashed into the working chamber is supported by the air compressed in the working chambers.
