There are many losses within the engine itself including friction and waste heat from the combustion process. Using pneumatically driven actuators to shoot the valve open the camless engine concept can provide fully variable valve lift and fully variable lift duration without a camshaft in sight. According to Cargine Engineering, cams create a large amount of wasted energy and the camless ICE will remove that lost energy.
