Abstract
A method and a system for converting kinetic energy of a vehicle and part of energy supplied by its engine into energy of compressed air and using it to assist in vehicle propulsion later. A novel system of valves employing variable valve timing and valve deactivation is used to implement and control a two-way flow of compressed air between the engine and an air-reservoir where air-temperature control is maintained. During operation with compressed-air assist the engine operates both as an air-motor and as an internal combustion engine during each cycle in each cylinder. The engine can selectively and interchangeably operate either as a four-stroke or as a two-stroke internal combustion engine.
