摘　　要：GB 18285-2018《汽油车污染物排放限值及测量方法(双怠速法及简易工况法)》、GB 3847-2018《柴油车污染物排放限值及测量方法(自由加速法及加载减速法)》两个标准于2019年5月1日起实施。底盘测功机日常检查对保证简易工况法及加载减速法排放检验结果提供强有力的保证。本文研究底盘测功机日常检查策略,旨在帮助机动车检验机构提高排放检验的正确率。GB 18285-2018 "Limits and measurement methods for emissions from gasoline vehicles under two-speed idle conditions and shor t driving mode conditions" and GB 3847-2018 "Limits and measurement methods for emissions from diesel vehicles under free acceleration and lugdown cycle" have been implemented since May 1, 2019. The daily inspection of the chassis dynamometer provides a strong guar antee for the emission test r esults of the simple driving mode conditions, andlugdown cycle.This ar ticle studies the daily inspection strategy of chassis dynamometer s, which aims to help motor vehicle inspection agencies improve the accuracy of emissions inspections.
