Abstract:The designing method of cam profile aiming at improving the reliability of injection pump,and decreasing the shock between cam and roller is expounded.Transition function uses cosine compound function to replace cubic function,thus can enhance the fuel supply rate and acceleration of injection pump,and improve the reliability of injection pump.This method has Mready been used in the design of PMD injection pump.
