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

Disclosed are a method of determining a correcting logic for a reacting model of an SCR catalyst, a method of correcting parameters of the reacting model of the SCR catalyst and an exhaust system to which the methods are applied. The reacting model of the SCR catalyst is defined by m parameters and has n input variables, where m and n are natural numbers with n smaller than m. The reacting model of the SCR catalyst may be adapted to predict nitrogen oxide (NOx) concentration at a downstream of the SCR catalyst at the least.
