摘　　要：介绍了研究增压发动机动态排放问题的意义以及研究方法.采用了增压发动机动态性能模拟与稳态试验相结合的方法,建立了涡轮增压柴油机的准线性动态模型,利用稳态试验数据建立神经网络排放模型,提出了一种将2种模型结合起来在MATLAB/SIMULINK环境下的增压发动机动态排放预测仿真模型.The significance and research method of dynamic emission of turbocharged engine are described in the paper. The research method is used, which combines the turbocharged engine dynamic performance simulation with the steady test. A quasi linear dynamic simulation model for turbocharged diesel engine is established. Neural network based emission model is established using the steady test data. A prediction simulation model of turbocharged engine dynamic emission is proposed based on MATLAB/SIMULINK.
