摘要：
According to the design and experimental parameters, a GT-Power simulation model of a turbocharged diesel engine is established and the accuracy of the model is verified. The influence of the advance angle of the fuel injection on the performance of the diesel engine in altitude environment, achieved by changing the atmospheric pressure, at rated speed is studied. The trend of the best injection advance angle in different working conditions is determined. The results show that with the decrease of atmospheric pressure, increase the injection advance angle in a certain range will improve the performance of the diesel engine, which manifest as increase in power and reduce the fuel consumption rate. However, the disadvantage is due to the increase of cylinder temperature and burst pressure, safety performance deterioration.
