发动机阻力矩测试方法研究

摘要

通过整车道路带挡滑行和底盘测功机反拖汽车两种方法测试发动机阻力矩。对汽车不同挡位、不同行驶里程的试验结果进行对比分析，得出试验方法的具体注意事项。阐述发动机阻力矩试验结果在汽车燃油经济性计算上应用。%Two Methods of vehicle coasting on the road with transmission drive position and dynamometer dragging vehicle are ap-plied to test engine resistance moment. To study and analyze the result of the vehicle at the different gear and miles of travel, some test methods of attention is gained. And this paper elaborates that the test result is applied to calculating the automobile fuel economy.
