Abstract: A rotary combustion engine having in its housing an insert coaxial with the spark plug, to define the shape and volume of the spark plug chamber and of the firing channel between the spark plug and the combustion chamber. The insert is formed of material of high heat resistance and high heat conductivity, and is contoured to provide smooth gas flow and to obviate areas of high heat concentration; the insert has its hoop strength relieved to enhance retention in the housing wall.

Abstract: The rotor for a rotary internal combustion engine has in each of its flank portions an elongated recess or pocket which is substantially narrower in width than the rotor flank so as to define between the recess and the rotor side faces two relatively large land portions in the flank surface. A plurality of ribs are circumferentially spaced with respect to the hub portion and radially extending between and interconnecting the flank surfaces along the sides and bottom walls of the pockets and the hub portion to thereby define a plurality of axially extending cooling fluid passageways adjacent the sides and bottom walls of each of the pockets. The bottom wall of each pocket has an extension integrally formed with said bottom wall and projecting axially from one side thereof to a point beyond the end of the surface of the hub portion adjacent said side of the bottom wall and which extension serves as a baffle for directing cooling fluid into said fluid passages.

Abstract: A liquid-to-gas heat exchanger having an internal ribbonlike flow passage for the liquid, having means in the passage of adding extended surface and of interrupting, separating, or causing turbulence in the boundary layer to increase the liquid side film coefficient of heat transfer. The heat exchanger is of cast construction, and is provided with external fins for the passage of air or other gas thereover.
