影响轻型汽车排放测试结果因素分析及对策研究

Factors Analysis of Affecting Light Duty Vehicle Emission Test Results and Countermeasures Research

对影响轻型汽车排放测试结果的因素进行了分析,并研究了相关应对策略。主要从测试环境,车辆,测试系统密封性,测功机,冷却风机及超低排放测试系统方面进行了研究分析,并给出了具体的解决方法。

Analyze the factors which influence the exhaust gas emission measurement results accuracy of light duty vehicle and study the corresponding countermeasures. Analyze mainly these fac-tors in terms of testing environment, light duty vehicle, testing sys-tem airtightness, chassis dynamometer, cooling fan and ultra-low emission testing system and point out solid solution.
