METHOD AND DEVICE FOR CONTROLLING A PUMP CONNECTED TO A FUEL RAIL

摘要

A method and an apparatus for controlling the pump which is connected to the fuel rail are provided to improve the pump output control by supplying the predetermined fuel of amount through the pump after determining the output of the pump. A method and an apparatus for controlling the pump which is connected to the fuel rail comprise a step that determines whether the process of respecting to switch the internal combustion engine with the predetermined operating state is generated or not; a step for determining the pump output(MFP) of pumps(14) in sensing the process for switching the internal combustion engine with the predetermined operating state; a determining step the output of the pump the predetermined fuel of amount is provided for the operating state; and a step for operating the pump to provide the fuel of the predetermined amount.
