Abstract
Applied software GT-FUEL to build up the physics and the mathematics model of the 16V280ZJ diesel engine' electronics injection system. Ask for the help of solenoid valve to control feeding timing and feeding quantity in order to research on optimization of injection pressure and injection rate curves. In contrast with the experiment of the machine injection system to elaborate the superiority of the electronic control system .It showed that optimizing the fuel injection system by GT-FUEL is doubtlessly practical and theoretically estimable for it could not only cut down the experimental workload but uncover some physical phenomena out of reach for experimental investigations.
