Regeneration von Partikelfiltern bei Benzin- und Dieselkraftfahrzeugen

In order to comply with the particle emission limits for motor vehicles as part of the type approval test in accordance with European Regulation (EC) 715/2007, the vehicle manufacturers install particle filters (Diesel Particulate Filters (DPF)/Gasoline Particulate Filters (GPF)) in the vehicle’s exhaust system. Regeneration must be initiated at the latest when a critical soot mass is reached in the filter. The regeneration takes place by burning off the soot stored in the filter. The carbon content of the particles is oxidised with oxygen above approx. 600°C to form carbon dioxide. The regeneration strategy of the vehicles varies. A basic distinction is made between periodic (active) and continuous (passive) regeneration. Periodic regeneration is used almost exclusively for diesel vehicles and continuous regeneration for vehicles with gasoline engines.
The aim of the research project is to measure the vehicle emissions during particle filter regeneration and to evaluate them with regard to their change compared to driving without regeneration.
