Summary
Most new diesel vehicles in Europe are equipped with diesel particulate filters (DPF) to meet the emission standards as well as to reduce health risks associated with fine diesel particulate matter. Like other automobile manufacturers in Europe, Hyundai Motor Company (HMC) offers most of its diesel engine powered vehicle models with diesel particulate filters. A filter system with SiC substrate, without additive support and fuel post injection in order to increase the temperature for regeneration is used. This paper describes in one part the development issues related to the DPF system, including the DPF system layout and regeneration strategies. The latter comprises the different methods to determine the soot mass in the filter and to set the criteria to initiate the regeneration of the DPF. A second part deals with the validation and verification of the implemented DPF system application and regeneration strategy in an extended fleet testing of several tens of vehicles under various driving conditions (rural road, highway, city) for in total more than 5 Mio. km.
