In the near future the effort on the development of exhaust gas treatment systems must be increased to meet the stringent emission requirements. The complexity of exhaust lines will increase dramatically due to the use of new catalyst and filtration units (Diesel Particle Filters) and emission control is merging with powertrain management. The numerical simulation is an important tool that supports the design of these systems.
This paper presents a generic model for the chemical reactions that are occurring during the regeneration of a DPF (Diesel Particle Filter). Validation results for the forced regeneration of a catalyzed soot filter are shown. The transient heat-up of a close coupled catalyst is shown as an example.
