摘要
在底盘测功机上 ,按排放法规规定的 15工况对国产小货车进行了排放测试 ,分析了对应工况法中发动机转速、输出转矩和功率的变化规律 ,讨论了整车各运行工况下发动机负荷的大小及其变化情况 ,其结果有助于改善工况法中相应发动机运转状况下的汽车排放 .
Test of a domestic light truck is performed on the chassis dynamometer according to 15 running modes of vehicle exhaust legislation. The varying principle of engine speed, power and torque output corresponding to running modes is analyzed. And the engine load and its variation with complete vehicle running modes are also discussed. The results may help to reduce vehicle emissions at corresponding engine running modes.
