An air motor with regenerating system which was designed for a bicycle was developed, and the air motor was driven by compressed air without gas emission. The purpose of this study is to elucidate characteristics and regeneration performance of air motor, and the effect of supply air pressure and rotational frequency on output power were experimentally investigated. The maximum cylinder pressure increased as the supply air pressure increased, although the maximum cylinder pressure was less than the supply air pressure. The maximum cylinder pressure reduced as the revolution frequency increased because the inlet valve opening duration was decreased. Therefore, the output power can be improved by the optimization of valve timing. The output power and flow rate increased with an increase of supply air pressure, however both were decreased as the revolution frequency increased due to friction loss. The regeneration pressure was decreased in case of high revolution frequency.
