摘　　要：基于发动机平均值模型,运用LabVIEW图形化编程功能构建发动机进气系统模型,结合稳态试验数据对模型进行拟合和修正。控制试验发动机在不同转速和节气门开度下稳态运行,并比较试验数据和模型仿真计算值,所得数据误差在±8%以内。By means of programming module in LabVIEW ,the intake manifold model is built based on mean value model .Combined with the steady-state test data ,the model is fitted .Controlling engine at different speed and different throttle opening on steady-state operation and comparing the calculated value of model simulation and the value of test ,the relative error is less than 8% .
