Real-Time Capable, System-Level Simulation With Integrated Pollutant Formation and Exhaust Aftertreatment Modeling
Published October 12, 2011 by Society of Automotive Engineers of Japan in Japan
Today's diesel engines require a combined design and application of combustion strategies with various aftertreatment devices. A comprehensive simulation approach is presented with the aim to support engine development activities in the virtual environment. Combustion and pollutant production models are applied in a real-time capable engine and vehicle simulation model considering crank-angle-resolved phenomena as well as pollutant conversion in a diesel oxidation catalyst (DOC) combined with urea injection and selective catalytic reduction (SCR). Extended species transport model is applied taking into account an arbitrary number of chemical species and reactions in the entire system.
