In order to improve fuel economy and reduce emission of city buses with special driving situation, a breaking energy regeneration system was developed and a hydraulic energy saving equipment was structured by using high and low pressure accumulators, plug-in valve, variable hydraulic unit and other accessories were designed. The energy saving efficiency has also been discussed. The equipment is simple in structure with high reliability.
