Abstract
Every year, stricter regulations are imposed on diesel engine emissions. It is difficult to satisfy these regulations only by improving the combustion improvement techniques in the near future. To overcome the problem, a treatment method of diesel particulate matter (PM) using ozone at a relatively low temperature is proposed. An experimental evaluation of a diesel particulate filer (DPF) is performed by regulating the exhaust gas temperature. From the evaluation, the DPF regeneration is achieved at the 180, 250 and 290°C. Among them, the highest performance of the DPF regeneration is achieved at 250°C with the efficiency of 7.10 g(PM)/kWh. The plasma energy required for DPF regeneration is only 0.24% of the power generated by the engine
