A system utilizing a pressure storage vessel for initially charging a first air cylinder of a series of air cylinders. Valve means admits a flow of pressurized air, in a sequential manner, into the cylinders for piston movement downwardly to compress spring members to a loaded condition. Additional valve means, closed during downward piston movement, are subsequently actuated to permit discharge of an air impulse, by the action of said spring combined with a second source of air pressure acting on the underside of the piston. The last cylinder of the series is operable to impart a force to a media for the operation of a motor for powering a vehicle.
