Emission control system including an oxidation catalyst and selective catalytic reduction catalyst
摘要：
An emission control system is provided. The emission control system includes an oxidation catalyst having a precious metal loading of less than 100 grams (g)/cubic foot (ft3) and a selective catalytic reduction (SCR) component positioned downstream of the oxidation catalyst operated between 150° C. and 300° C. during engine operation to reduce the formation of N2O in the selective-catalytic reduction component.
摘要（中）：

提供排放控制系统。 排放控制系统包括氧化催化剂，该氧化催化剂具有小于100克（g）/立方英尺（ft 3）的贵金属负荷和选择性催化还原（SCR）组分，其位于在150℃和300℃之间操作的氧化催化剂的下游 在发动机运行期间以减少选择性催化还原组分中N 2 O的形成。
