Simulated exhaust systems

  • 12-Aug-2010 11:13 EDT


dSPACE’s ASM Diesel Exhaust Model offers a complete virtual diesel exhaust aftertreatment system. In addition to the submodel for urea injection (the selective catalytic reduction [SCR] system), it includes further submodels for a diesel oxidation catalyst (DOC) and a diesel particle filter (DPF). The simulation model can be used throughout the development process, from controller design in Simulink to electronic control unit (ECU) testing on a dSPACE simulator. A special feature of the model is that users have complete access to all its Simulink blocks. Users benefit from being able to view the modeled functions and adapt them to specific requirements themselves. The exhaust model’s individual components (DOC, DPF, SCR) can be combined in different ways and optimally configured for the aftertreatment system under test. The model can be used to represent the essential physical and chemical processes in modern aftertreatment systems: urea decomposition for catalytic reduction, fuel post-injections for catalytic oxidation, soot particle filtering, and DPF regeneration.
