摘要

This paper describes the development and characterization of a Selective Catalytic Reduction (SCR) catalyst system for EUIV (HDD) engines. The performance of the SCR catalyst and the impact of catalyst volume are described. The effect of using an ammonia slip catalyst behind the SCR catalyst is investigated. The durability of the SCR catalyst is described. Finally, examples of the use of computer modeling to refine the optimum volume and urea injection strategy are given. The results demonstrate how a combination of practical experiments and computer modeling can be used to refine the system and provide a cost-effective exhaust aftertreatment solution.
