Abstract
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.
