Fuel injection control strategy for electronic unit pump of diesel engine

The electronic unit pump originates from electronic pump injector.Due that a high-pressure pipe is added between the electronic pump and fuel injector,the time delay from electronic control signal sending to cylinder fuel injection is lengthened.By considering the program computational time and solenoid-valve response property as additional injection time,a timing control strategy is designed for fuel injection.As such,it is found from experimental results that the electronic control unit can precisely and flexibly control the injection timing and volume.
