A rotary engine including a hollow housing having an irregular but generally cylindrical cavity therein and a shaft journalled through the cavity in off-center relation thereto. The curved walls of the housing defining and extending about the cavity gradually increase and decrease in radial distance from the axis of rotation of the shaft but the spacing between all working curved wall portions of the cavity lying at opposite ends of all diameters of the aforementioned axis is constant. An elliptical rotor is mounted on the shaft within the cavity for rotation with the shaft and for shifting radially of the axis of rotation of the shaft along a line extending between the vertices of the rotor while fuel mixture and exhaust by-products inlet and outlet means and fuel mixture ignition means are spaced about the outer periphery of the cavity. Also, the rotor and shaft define a rotary assembly having axially extending air passages extending therethrough opening through opposite ends of the housing with air vane structure carried by one end of the rotary assembly operative to pump cooling air through the air passages in response to rotation of the assembly.
