Abstract
A rotary heat engine has a cylindrical engine block containing a rotor with four equally spaced pistons and corresponding cylinders extending radially in the rotor. The pistons are pivotally connected to connecting rods that are in turn connected to a shaft at an inner end of each connecting rod. The engine block has a cover thereon and the block can have heating and cooling locations that create heating and cooling chambers within the rotor, thereby causing the pistons to reciprocate and causing the rotor to rotate within the engine block. The pistons reciprocate within the rotor while the rotor rotates within the engine block.
