ABSTRACT:
An internal combustion engine of the rotary type comprises a housing or block provided with a cavity which is cylindrical in one portion and enlarged in another; the side walls of the cavity are flat. A drive shaft is rotatably mounted in the housing for rotation about the axis of the cylindrical portion of the cavity and a cylindrical rotor is mounted in fixed relationship eccentrically on the shaft. The throw of the eccentric is somewhat less than the radius of the cylindrical portion so that the eccentric acts as an impeller driving air around the cylindrical portion of the cavity with some blow-by of air and no metal to metal contact. A pair of fluid barriers or partitions are pivoted at their outer ends on the wall of the cavity and have their opposite ends biased against the rotor in sealing engagement. The partitions thus divide the cavity into a combustion chamber and an air pumping chamber. The air pumping chamber is further divided into an air intake chamber and an air compression chamber, these communicating through the restricted space between the rotor and the wall of the cylindrical portion of the cavity. The side walls and the rotor and partitions are in sliding sealing engagement. The ignition system may be conventional, timed in accordance with rotor positions. The fuel injection system is of the electronic solenoid actuated type adapted for use on the rotary engine of the disclosure.
