Abstract
A new method that optimizes the control map of hydrocarbon addition to diesel exhaust gas for hydrocarbon selective catalyst reduction (HC-SCR) has been developed. This method is comprised of a numerical HC-SCR model and a new optimization technique using Evolutionary Programming based on the evolution of living things. As a result of this evaluation, the number of calculations to obtain the optimized control map with this method was one third that using the conventional method. By using the obtained optimized control map, the NOx conversion was found to be greater by 18% than that with the constant addition of hydrocarbon.
