摘要
介绍了目前国内外用于柴油机排气微粒 (PM)测试的稀释取样系统的工作原理 ,并对其优缺点进行了比较。全流稀释取样系统费用高 ,但能满足世界各国排放法规的要求 ,能对PM排放进行精确测量 ;部分流稀释取样系统投资小。
The principles of dilution sampling system of particulate emission measurement for automotive diesel engine are described. The merits and demerits of these systems are compared. The full flow dilution sampling system is expensive, but it can meet the requirement of emissions standards on particulate measurement. Particulates emissions can be measured accurately by using the full-flow system. Partial flow dilution sampling system is cheap and therefore used widely.
