摘要: PURPOSE: An exhaust filter for a vehicle and an exhaust apparatus with the same are provided to improve a fuel ratio by increasing the temperature of exhaust more than regeneration temperature without using much fuel. CONSTITUTION: An exhaust filter for a vehicle comprises first and second layers. A first hydrocarbon trap for absorbing hydrocarbon contained in exhaust is coated on the first layer. A first oxidation catalyst for oxidizing the hydrocarbon is coated on the second layer. The hydrocarbon absorbed into the first layer is desorbed at high temperature. The desorbed hydrocarbon is oxidized on the second layer, and the temperature of the exhaust increases. [Reference numerals] (AA) Exhaust gas

摘要: A catalyst capable of removing nitrogen oxides contained in exhaust gas satisfactorily, which comprises a monolith carrier and an under layer containing a cerium oxide-containing catalyst component and an upper layer containing a catalyst component containing both at least one member selected from the group consisting of copper, manganese, iron, cobalt and nickel and zeolite, both of which layers cover the carrier. The catalyst exerts oxidation catalysis due to the catalyst component contained the upper layer to accelerate efficiently the oxidation of nitrogen oxides contained in exhaust gas, particularly, the oxidation of nitrogen monoxide (NO) into nitrogen dioxide (NO), and the nitrogen dioxide thus formed is adsorbed by the cerium oxide contained in the under layer. Further, the catalyst can exert satisfactory catalytic activity even at a low temperature range of about 100°C, e.g., 80 to 150°C, so that the catalyst can significantly reduce or remove nitrogen oxides (NO) contained in exhaust gas even at low temperature.
摘要翻译: 一种能够令人满意地除去废气中所含的氮氧化物的催化剂,其特征在于,其包括整料载体和含有含氧化铈的催化剂组分的下层,以及含有含有选自以下的至少一种的催化剂组分的上层: 铜,锰,铁,钴和镍和沸石,两者都覆盖载体。 由于含有上层的催化剂成分,催化剂发生氧化催化作用,有效地促进废气中所含的氮氧化物的氧化,特别是将一氧化氮(NO)氧化成二氧化氮(NO),从而形成二氧化氮 被下层中含有的氧化铈吸附。 此外,即使在约100℃,例如80-150℃的低温范围内,催化剂也能发挥令人满意的催化活性,因此催化剂即使在低温下也能显着地还原或除去废气中所含的氮氧化物(NO) 温度。
