工况排放测试用ndv值的计算方法

Calculation Method of ndv Value for Emission Testing under Driving Conditions

摩托车排气污染物测试中,工况排放的测试是非常重要的,影响因素也是最多的。在进行工况排放测试时,不仅要保证测试环境条件、油品的一致性,更要保证底盘测功机和工况排放分析仪计量有效性,同时还需要根据车辆的性能参数设置对应的换挡信息,保证所有被测车辆在同一条件下运转,保证测试的一致性。

In the test of motorcycle exhaust pollutants,the test for emission under driving condition is very important,and it has most influencing factors.In the emission test under working condition,it should ensure the consistency of the test environmental conditions and oil products and the effectiveness of the chassis dynamometer and the emission analyzer.It is also needed to set the corresponding shift information according to the performance parameters of the vehicle to ensure that all the tested vehicles operate under the same conditions to ensure the consistency of the tests.
