Abstract

Using Portable Emission Measurement System (PEMS in short), the PM and gaseous pollutants emission in China light-duty diesel vehicle before and after installing DOC+POC under cold and hot start conditions are studied respectively. Meanwhile, the POC filtration efficiency and size distribution of both particle number concentration and mass concentration are analyzed. The result show the PM emission from vehicle installed POC can meet China standard, and the filtration efficiency of both particle number and mass is 25%~55% under cold and hot start. POC filtration efficiency under cold start is 10% higher than hot start. However, the filtration efficiency is different under different size distribution. PM is generated mainly in acceleration process.
