Method for controlling common-rail injection system of combustion engine of motor car, involves predicting calculation of injection quantities and value of operating parameter at time point based on time offset of setpoint value profile

摘要

The method involves utilizing a high pressure pump for supplying fuel. A rail/accumulator is connected with a fuel injector. Injection quantities are calculated at a time point based on an operating parameter of an internal combustion engine. The calculation of the injection quantities and a value of operating parameter are predicted at injection time point based on time offset of setpoint value profile and a time reference value profile. Rail pressure operational parameters are included in the high pressure pump. Independent claims are also included for the following: (1) a device for controlling a fuel injection system of a combustion engine (2) a combustion engine.
