【Abstract】 This paper illustrates purposes of developing PM pump through analyzing the art-of-state of fuel injection system in the world. This paper emphasizes on recounting structure features and technical measures for high injection pressure of PM pump. Meanwhile, this paper recounts designing requirement and features of RWS governor that matches PM pump and aims at demands of EURO II emission regulation for diesel engine. The testing results show that PM pump can meet performance and EURO II emission regulation demands for light vehicle diesel engine.更多还原
