组合式碳氢化合物捕集器和催化剂
摘要：
本发明提供一种用于降低冷启动碳氢化合物排放物的组合式碳氢化合物捕集器/氧化催化剂系统。碳氢化合物捕集器包括整体式载体，整体式载体包含沸石和包括浸渍在载体中或涂覆到载体上的镍和铜的混合物的催化剂。碳氢化合物捕集器可以设置在车辆的尾气通路中，使得碳氢化合物在捕集器中吸附和存储，直到发动机和尾气达到足以解吸和氧化碳氢化合物的温度。
摘要（英）：

A combined hydrocarbon trap/oxidation catalyst system is provided for reducing cold-start hydrocarbon emissions. The hydrocarbon trap includes a monolithic substrate containing zeolite and a catalyst including a mixture of nickel and copper which is impregnated into or wash coated onto the substrate. The hydrocarbon trap may be positioned in the exhaust gas passage of a vehicle such that hydrocarbons are adsorbed on the trap and stored until the engine and exhaust reach a sufficient temperature for desorption and oxidation of the hydrocarbons.
