Crutchfield, M R

A rotary internal combustion engine having a housing defining a chamber is disclosed. A fixed shaft extends coaxially through the chamber. A plurality of vanes are pinned to a collar which is rotative about the shaft. One vane is rigidly secured to the collar. A cylindrical drum is positioned in the working chamber with the centerline of the drum radially offset from the centerline of the working chamber. The vanes extend through slots or apertures in the rotor to close proximity with the chamber wall. A fuel delivery system communicates with the chamber through approximately 90 degrees of the compression cycle. An exhaust opening communicates with the chamber at the end of the expansion cycle whereby the compression ratio is substantially less than the expansion ratio. In one embodiment means are provided to vary the compression and expansion ratios.
