DPF technology has been considered as one of the most effective methods for reducing diesel particulate emission. PSA Peugeot Citroen introduced the DPF equipped diesel passenger car, Peugeot 607 HDI Sedan, in 2000 for the first time in the world, in which SiC filter, an oxidation catalyst, cerium based fuel born catalyst and post-injection technology were used for PM regeneration. In the present study, the characteristics of the Peugeot 607 DPF system were studied on chassis dynamometer and real road driving conditions. The change of emissions and fuel economy during 80,000km operation were also tested. Additionally, ash contents accumulated in the DPF filter was analyzed and particle size distributions was investigated after running of 80,000km.
