ABSTRACT:
An improved internal combustion engine of the type having a relatively high surface to volume ratio. An exemplary embodiment depicts the invention in a rotary engine having a rotor within a combustion chamber. The surfaces of the rotor that are exposed to the gases of combustion are provided with a plurality of pockets. Within each pocket is a heat insulating medium. The pockets are covered by a plurality of individual covers, one for each pocket. Heat flow to the rotor is thereby reduced to increase engine operating efficiency.
