Abstract

This paper introduces a new model for describing dynamics of a diesel engine aftertreatment system with diesel oxidation catalyst (DOC) and diesel particulate filter (DPF) components for reducing diesel particulate emissions. The system model results in high-index nonlinear differential-algebraic equations (DAEs), which give more general description of the system as compared to ordinary differential equation (ODE) approximations. A singularly perturbed sliding manifold (SPSM) approach is employed for model realization. Simulation results of a soot regeneration sequence show good agreements with that of experimental work. The model will be used for aftertreatment system soot regeneration control applications.
