Calibration for Fuel Injection Parameters of the Diesel Engine Working at Plateau via Simulating

In order to simulate the engine plateau characteristics, the 0-D Predictable Combustion Model Based on Neural Network was put forward firstly. Based on this combustion model, the integrated turbocharged diesel engine numerical model was established and then validated by experimental data. For the sake of improving engine performance at plateau, a measure is introduced in this study, which adapts the fuel injecting parameters at various altitude environments. And then the method to calibrate the injection parameters is proposed. Thus, three different simulating schemes at plateau environment had been put forward and the simulation results were compared later. Eventually, the outcome demonstrates that it is effective to advance injecting timing together with adjusting fuel mass; for instance, the rated power will recover to 89.7% of the plain value, once applying this adaption method at 4500 m altitude.
