METHOD OF DETERMINING CORRECTING LOGIC FOR REACTING MODEL OF SELECTIVE CATALYTIC REDUCTION CATALYST, METHOD OF CORRECTING PARAMETERS OF REACTING MODEL OF SELECTIVE CATALYTIC REDUCTION CATALYST AND EXHAUST SYSTEM USING THE SAME

摘要

The present invention relates to a method to determine a correcting logic for a reacting model of a selective catalytic reduction, a method to correct a parameter of a reacting model of selective catalytic reduction, and an exhaust system using the same. The present invention has an effect of correcting the parameters of a reacting model through a sensitivity analysis of the reacting model to define a reaction of the selective catalytic reduction. The reacting model of selective catalytic reduction (SCR) is defined by m parameters, and has n input variables which is smaller than m. The reacting model of the selective catalytic reduction is capable of predicting a concentration of nitrogen oxide at least on a rear end of the SCR.
