在用柴油车烟度排放检测方法

Testing Methods for Smoke Emission of In-use Diesel Vehicles

对现行的柴油车烟度排放检测方法进行了评述,指出了其不足之处.在此基础上提出了新的可行的检测方法.新检测方法根据柴油车的用途和对大气污染分担率的不同,提出不同的检测手段.针对应用有负载检测方法进行烟度排放检测的柴油车辆,提出了根据其实际运行工况的检测方法.这些检测方法能准确检测不同类型柴油车辆的烟度排放状况,不损害车辆,方便检查站检测,能对有效控制柴油车辆烟度排放对大气的污染、保障人体健康起到促进作用.

This paper comments on the present smoke emission test methods for in-use diesel vehicles and points out their disadvantages. New methods are put forward accordingly. The new methods consist of three types according to the application of the diesel vehicles and the differences of the sharing percentage of air pollution. For those diesel vehicles whose smoke emission is tested with loaded inspection methods, different test methods are given according to their traveling modes, which provide accurate smoke emission test for different types of diesel vehicles, do no harm to tested vehicles and is easy for testing station to operate, and manage the vehicles＇ smoke emission efficiently.
