用于测量轻型车超低排放的分流稀释气袋取样系统

Bag Mini-diluter Sampling System Used in Light-duty ULEV Emission Measurement

介绍了轻型车用微型稀释气袋取样系统 (简称BMD)排放测试系统的特点。引用传统CVS和BMD测量ULEV/SULEV排放水平的测量误差对比数据 ,论证应用BMD进行超低排放测量的可行性和优越性 。

This paper presents the feature of bag mini-diluter(BMD) s ampling system.Based on the contrasting data of test error of ULEV and SULEV emissions using both BMD and traditional CVS metho ds,the feasibility and advantage o f BMD sampling system in SULEV emi ssion measurement are demonstrated compared with traditional CVS syst em.
