In this study, we used our own integrated emission prediction model to predict whether EURO7-compliant commercial internal combustion engine vehicles would meet the regulations. In particular, the optimal value of urea water injection and EHC control strategy for each combination of the specifications of the close-coupled SCR system (volume, substrate spec., electric heating catalyst (EHC), etc.) was derived. Through this, it was intended to derive the best specification combination in terms of control, durability and material cost, and to use the results as a basis for decision-making in the early stage of product concept selection.
