Development Of Diesel Engine Electronic Unit Pump Control System Based On XC164

To respond to the challengers of global energy shortage and environmental problems,the automotive industry has been making great efforts in the field of power sourcing, oneof which is to install more diesel engines instead of gasoline engines. Electronicallycontrolled unit pump fuel injection system makes diesel engines get better fuel economy,power and lower emissions.As the electronically controlled unit pump fuel injection system is able toindependently control injection timing, to creat a high pressure, it works a lot inachieving the best matching of emissions, power and economy of diesel engines.To make the use of EUP systems more convenient in the above sdudy of engines, thepaper developes a control platform to dominate the fuel injecting system which has thefollowing features: The control system is mainly for four-cylinder high speed dieselengine and can be used in both pump bench tests and engine bench tests. To achieveaccurate controlling of injection timing and injection pulse width, this paper designs eachmodule of the ECU according to features of EUP system and resources of infineonXC164; To communicate with calibration tool via CAN module on XC164and peripheralcircuit on ECU, this paper developes a calibration tool for this control system and it has agood user interface running on PC; This control system can achieve starting normally,idle speed closed-loop controlling, engine stopping injection and so on.All of the software modules, hardware modules and control strategy of the controlplatform for EUP injection system are verified on a pump stand. All the tests show thatthe control system works well and all goals are reached.
