Study on Design Criteria and Methods for the Valve Train of the Compressed-Air Engine

Abstract:

The Compressed-air (CA) engine car is receiving increasingly worldwide attention because it takes advantages of renewable energy and has zero exhaust emissions. However it is limited by its low efficiency. This paper focuses on a systematic study on valve timing for optimizing its efficiency and performance. The requirements for the valve train were presented and an optimized polynomial cam profile was applied. Using the programme of Matlab, the influences of the half wrap angle and the maximum valve lift to the fullness coefficient were studied. The article proves that the designed cam profile should use the minimum maximum valve lift to receive the maximum fullness coefficient.
