Reduced-Order models for a LNT-SCR Diesel After-treatment Architecture with NO/NO2 Differentiation

Abstract : LNT and SCR are two leading candidates for Diesel exhaust nitrogen oxide (NOx) after-treatment. This paper deals with the modeling of the architecture combining the two systems in series with NO/NO2 differentiation, induced directly by the widening and hardening of the future standards. Model reduction is performed to allow for real-time automotive applications. Based on simplified chemistry and slow-fast dynamics assumptions, a complete reduced model is proposed, suitable for on-board diagnosis and model-based control. Validation has been achieved through extensive experiments.
