摘要 为研究柴油机颗粒物捕集器(DPF)泄漏问题,通过柴油机氧化催化转换器(DOC)与DPF并联,调节两者的流通面积比来反映DPF不同的泄漏程度,建立基于GT-Power软件的DPF泄漏故障仿真模型,测得仿真模型相应的排气背压以及排气温度等主要特征参数。再以排气阻力试验结果对仿真模型进行验证与优化,最后依靠发动机台架试验结果进一步验证优化后仿真模型的正确性。模拟结果表明:利用GT-Power软件建立的泄漏故障模型,来提取DPF泄漏故障排气背压以及排气温度等主要特征参数,是准确的、可靠的。 To study the leakage fault of diesel particulate filter(DPF),by paralleling diesel oxidation catalyst(DOC)with DPF and regulating their flow area ratio to reflect the different leakage degree,the paper firstly establishes a simulation model of DPF leakage fault with GT Power software,and tests the main feature parameters of the model,such as exhaust back pressure and temperature.Then,it verifies and optimizes the simulation model with the result of exhaust resistance test,and proves the correctness of the optimized simulation model by engine bench test.The simulation result shows that establishing leakage fault model with GT Power software to extract the main feature parameters of DPF leakage fault is accurate and reliable.
