车用发动机动态排放测试系统及其应用

Application of Dynamic Emission Test System of Vehicle Engine

介绍了某汽车开发中心发动机动态排放测试系统的系统构成、系统集成方法及部分试验结果。提出了发动机动态排放测试系统的具体构成,比较分析了发动机/测功器控制子系统的各种类型。由此,得出动态排放测试系统的设备选型及实施方案,并通过图形给出系统安装调试完成后的试验结果。

The structure,integration method and partial test results of engine dynamic emission test system in an automotive R/D center are introduced.The specific compositions in engine dynamic emission tests are put forward and various types of engine/dynamometer control sub-systems are compared and analyzed.The equipment model selection and implementation method for dynamic emission test system are thus obtained,and test results are given by figure after the system is installed and adjusted.
