摘　　要：以4190型船用中速柴油机为研究对象,利用MATLAB/Simulink软件建立柴油机工作过程仿真模型,通过仿真结果与实验数据的对比,验证模型的正确性。将该模型的配气相位偏移量进行由负到正的变化,得出其对柴油机功率、扭矩、燃油消耗率、缸内最高温度、最高爆发压力、NOx排放、排气温度、充气效率的影响规律。仿真结果确定了4190型柴油机最佳配气相位值:进气提前角66℃A;进气滞后角54℃A;排气提前角58℃A;排气滞后角56℃A。为4190型柴油机的性能优化改造提供了理论依据。The working process model of the 4190 type marine medium-speed diesel engine has been established with the MATLAB/Simulink software. The accuracy and dependability of the model were verified by comparing the simulation results with experimental data. The influence law of gas phase offset on diesel engine power,torque,fuel consumption rate,combustion temperature,combustion pressure in cylinder,NOxemission,exhaust gas temperature,charging efficiency was studied through simulation with the model. The optimized gas phase has been identified that＇s,inlet advanced angle 66℃ A（ crankshaft angle）; intake lag angle54℃ A; exheaust advanced angle 58℃ A; exhaust retard angle 56℃ A,conclusions are drawn that the simulation results are beneficial to the performance optimization of 4190 type marine diesel engine.
