A diesel oxidation catalyst is required to remove hydrocarbons, carbon monoxide, and soluble organic fraction from the diesel engine exhaust gas stream. The emissions and the exhaust system of diesel light-duty diesel vehicles were analyzed with the intent of enhancing the low temperature catalytic activity and optimizing the aftertreatment system. The study reported hereunder was focused on the catalyst activity and durability, the thermal management of the{{br}}system, and the enhancement in emission selectivity through via the precious metals. This paper describes the appropriate materials and their composition as a diesel oxidation catalyst. The paper also describes the optimum precious metal loading for the diesel oxidation catalyst. With the respect to the aftertreatment system, this paper proposes the overall oxidation catalyst system structure (i.e. substrate arrangement, substrate volumes, substrate cell densities, etc.). It also describes the modifications made to the system to improve emissions performance and to reduce{{br}}the total system cost. The test results show that the proposed system exhibits an improvement in emission reduction performance compared to the previous standard baseline. |
