Abstract：In order to solve the problems that the traditional diesel engine SCR test bench can not control the catalytic reaction temperature and the test results are not accurate for different capacity engine test adaptability,this study based on the conventional test bench, an SCR test bench for diesel engine that is capable of controlling the catalytic reaction temperature was designed. The bench adaptability and the accuracyaccuracy of measurement can be improved to provide reliable test conditions for SCR system measurement and improvement.
