Abstract
A multiple-cylinder combustion engine includes a counter rotating system eliminating any vibratory pitch, yaw, and roll torques. The net angular momentum of all rotating parts in the engine is equal to zero. The multiple-cylinder combustion engine activates or deactivates the number of the cylinders without any additional pitch, yaw, and roll torques.
