A small size fuel free motorized engine for transportation is provided. We propose to use compressed air in a closed-loop operation between two different boundary conditions as follows: A. Introducing compressed air into a cylinder induces energy in the second energy loop inside the cylinder through the balance of pressure; and B. Extracting the compressed air from the cylinder back to its recipient consumes energy to recover its initial state. As the energy induced in the second loop is greater than the energy spent on extraction from the cylinder back to the recipient, an energy gain is obtained during the movement of the gas between these two boundary conditions. This energy gain replaces fuel combustion energy for powering the engine.
