ABSTRACT:
An improved rotary engine including a housing having walls defining an operating chamber, a prechamber within the housing, an opening in one of the walls establishing fluid communication between the chamber and the prechamber, and means for introducing fuel into the prechamber. A shaft is journalled in the housing and extends through the chamber while a rotor is journalled on the shaft and within the chamber. The rotor has a surface cyclically brought into proximity with the wall including the opening and the opening therein for cyclically compressing an oxygen-containing medium within the prechamber. Means, including a portion of the surface, are employed for varying the effective size of the opening to thereby control the flow of combustion gases from the prechamber to the chamber at a desired rate to achieve a desired combustion characteristic.
