The Applications of Piston Type Compressed Air Engines on Motor Vehicles

This study presents the applications of piston type compressed air engine on a small size motor vehicle. A conventional 100cc four-stroke internal combustion engine(IC engine) was modified to a two-stroke compressed air engine and the power output has been examined with different intake valve timing and supply air pressures on a test bench. The compressed air engine was installed on a motorcycle for the demonstration of vehicle application. The success of this application demonstrates the concept of green energy vehicle with zero emission using compressed air energy. The motorcycle installed with the compressed air engine can operate at maximum speed around 38.2 km/hr. and distance up to 5 km.
