Abstract

Due to their adverse health effects and their abundance in urban areas, diesel exhaust ultrafine particles caused by the aftertreatment devices have been of great concern in the past years. An experiment of particles number emissions was carried out on a high-pressure, common rail diesel engine with particle oxidation catalyst (POC) to investigate the impact of POC on the number emission characteristics of particles. The results indicated that the conversion rates of POC is 32.4% - 95.9% with the average value of 61%. The conversion rate of POC decreased with the increasing particle diameter and POC has a good reduction effect on the nucleation mode particles. The geometric number mean diameters of particles downstream POC is bigger than those upstream POC, which means that POC has a higher conversion rate on the nucleation mode particles.
