机动车尾气排放检测方法对比分析

通过怠速、双怠速法对机动车尾气检测试验和数据对比分析表明,不同车龄段的电喷型轿车采用怠速法检测尾气达标率在73.3%～93.5%之间;双怠速法检测尾气达标率在40.0%～82.6%之间.不同车龄段的化油器型轿车采用怠速法检测尾气达标率在25.0%～57.1%之间;双怠速法检测尾气达标率在18.8%～57.1%之间.指出双怠速法对化油器车辆尾气控制同样有效果,双怠速法对筛选高污染车辆比怠速法更严格和科学.

The ContrastofM ethodsfor Vehicle TailGasExhaustTest

The test and data of idle state method and double idle state method for vehicle tail gas were analyzed. The rates of uesd in different year electronic injection autos exhaust up to standards were between 73.3% and 93.5% at idle state method test and the rates between 40.0% and 82.6% at double idle state method test. The rates of uesd in different year vehicle with carburetor exhaust up to standards were between 25.0% and 57.1% at idle state method test and the rates between 18.8% and 57.1% at double idle state method test. The double idle state method test had same function to control the exhaust of vehicle with carburetor and was even more strictly and scientifically in screening out high pollution vehicles than the idle state method test did.
