Method for operating fuel injection system for injecting fuel into combustion engine of motor in motor car, involves calculating required target flow of fuel using pump model of pump and calculating cross section of opening of engine

摘要

#CMT# #/CMT# The method involves calculating a required target flow of a fuel using a pump model of a pump (310) through a metering unit (308). A cross section of an opening of a combustion engine is calculated. Inlet pressure and rail pressure of the fuel in a fuel injection system (302) are provided with the pump model at the pump. Rotation speed of the combustion engine is provided with the pump model. The target flow is determined by the metering unit to adjust a rail pressure controller of the fuel injection system. #CMT# : #/CMT# An independent claim is also included for an arrangement for operating of a fuel injection system of a combustion engine to provide fuel. #CMT#USE : #/CMT# Method for operating a fuel injection system for injecting fuel into a combustion engine of a motor in a motor car. #CMT#ADVANTAGE : #/CMT# The method allows calculating the required target flow of the fuel using the pump model of the pump through the metering unit, thus operating the fuel injection system for injecting the fuel into the combustion engine of the motor in the motor car in an efficient manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of a pump model for a fuel injection system. 300 : Arrangement for operating fuel injection system of combustion engine 302 : Fuel injection system 304 : Control device 308 : Metering unit 310 : Pump.
