    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: An active metal, particularly cesium, impregnated hydrocarbon adsorbent, such as zeolite, comprises an improved hydrocarbon trap/oxidizing catalyst for use in effectively adsorbing hydrocarbons during automotive cold-start and subsequently desorbing, oxidizing and removing hydrocarbons during warmer operating conditions. The active metal modified hydrocarbon adsorbent may be combined in other forms of multi-layer automotive exhaust gas catalytic structures.
