Abstract

Apparatus and associated methods relate to a modular rotary engine with a rotating valve shaft assembly. The rotating valve shaft assembly controls the timing of operations that alternately load and seal compressed air in a plurality of adjacent combustion chambers and alternately unload the high-temperature, high-pressure combustion gases from the adjacent combustion chambers into one or more expansion modules. The rotating valve shaft assembly includes at least two rotating valve shafts. Each rotating valve shaft includes ports that alternately open to allow a flow of compressed air from the compression module into a combustion chamber; and close to allow the injection of fuel into the combustion chamber and ignition of the compressed air and fuel mixture. The rotation of the drive shaft of the rotary engine is powered by the expansion of expanding combustion gases that turns the expansion rotor.
