Abstract
A rotary engine employing an improved circumferential flow cooling system is employed to provide an increase in fuel economy and engine efficiency. Each housing unit has its own distinct flow circuit with the total volume of cooling medium being variably distributed among such units. The circuits employ flow foils, flow turbulizers, velocity variation and a variable epitrochoid wall thickness to provide flow characteristics which vary along the stations of the circuit. The variations promote a more uniform engine wall temperature throughout, the coolant can be operated at a higher overall temperature, and heat is transferred (extracted or injected) on a programmed basis along the flow circuit as needed.
