重型柴油发动机用于各种商用车辆。排放标准的最新变化导致在柴油发动机上使用氧化催化剂形式的催化排气后处理以减少颗粒排放。预计排气后处理将继续用于柴油发动机，以满足未来的排放标准。柴油氧化催化剂在减少的排放、排气操作条件和耐久性要求方面与当前的乘用车汽油催化剂显著不同。本文从柴油机排放、工况和耐久性要求等方面论述了柴油机催化剂的发展。发动机/催化剂系统的排放性能和柴油机氧化催化剂的排放耐久性的结果来支持这项工作的结论。
Heavy-duty diesel engines are used in a wide variety of commercial vehicles. Recent changes in the emissions standards have lead to the use of catalytic exhaust aftertreatment in form of oxidation catalysts on diesel engines to reduce particulate emissions. It is expected that exhaust aftertreatment will continue to be used on diesel engines in order to meet future emissions standards. Diesel oxidation catalysts differ significantly from current passenger car gasoline catalysts in terms of the emissions reduced, the exhaust operating conditions, and the durability requirements. This paper discusses the development of a diesel catalyst in terms of engine emissions, operating conditions and durability requirements. Results on emissions performance of an engine/catalyst system and emissions durability of a diesel oxidation catalyst are presented to support the conclusions of this work.
