Abstract

In this paper, the catalytic converter for SCR have been researched from these respects of carrier, coating and package. A catalyst has been designed based on these characteristics of carrier, coating, package . The reasons for the crystallization of urea in pipe are analyzed, in order to eliminate the crystallization the layout of exhaust pipe is optimized; and the best nozzle installation location is confirmed. To prove the performance of catalyst and the result of optimization of exhaust pipe layout, verification experiments are conducted. These results of experiment can meet European IV emission regulations.
