ABSTRACT:
A rotary internal combustion engine comprising an elongated rotor having an oval shaped cross-section secured to a compartmentalized shaft rotatably disposed in an elongated cylindrical shaped bore in a stationary engine block. A plurality of vanes, having a curved wedge-shaped cross-section, are pivotally secured to the block and arranged to move into the cylindrical shaped bore into sealing engagement with the outer surface of the rotor. Fuel and air are delivered through the compartmentalized shaft into chambers between adjacent vanes where fuel is compressed, ignited, and allowed to expand applying torque to the oval shaped rotor. The oval shaped cross-section of the rotor has long sides which are substantially straight and first and second arcuate ends. The first arcuate end of the oval shaped cross-section of the rotor has a radius of curvature which is substantially equal to the radius of the bore in the block such that the first arcuate end is closely spaced from and parallel to the wall of the bore for complete scavenging. The arc length of the first arcuate end of the rotor cross-section and the distance between fuel intake ports and exhaust ports is equal to or greater than spacing between adjacent vanes to isolate fuel intake ports from exhaust ports. The second end of the rotor cross-section has a radius of curvature which is less than the radius of curvature of the first end of the rotor cross-section such that maximum compression is achieved immediately prior to ignition of fuel. Products of combustion and fresh air are delivered to an exhaust compartment in the compartmentalized shaft before exhausting to atmosphere.
