Unlike conventional engines, it directly converts the combustion expansion force of combustible gas into driving torque. The basic structure of the ECH engine involves placing a rotor shaped like a Reuleaux triangle in an elliptical space. The three faces of the rotor divide the elliptical space into three independent combustion chambers. Due to the eccentric movement of the rotor, the volumes of these separated combustion chambers constantly change during operation, achieving the intake, compression, ignition, and exhaust processes required for a four-stroke cycle.
