    • PURPOSE: A smoke reducing device with an electrically heating foam filter is provided to maintain the temperature of a catalyst over activation temperature. CONSTITUTION: A smoke reducing device(100) with an electrically heating foam filter comprises an insulating body(111), a heating foam filter(130), and a collecting foam filter(150). Exhaust gas discharged from an internal combustion engine flows in and out of the insulating body. The exhaust gas is discharged to the outside through a plurality of exhaust holes. Harmful matters in the exhaust gas discharged through the exhaust holes are converted into harmless matters by a catalytic action. A surface of the heating foam filter is coated with a catalyst, and the catalyst is heated by electricity. The collecting foam filter collects particle matters in the exhaust gas discharged through the heating foam filter.
    • 目的:提供具有电加热泡沫过滤器的减烟装置,以保持催化剂的温度超过活化温度。 构成:具有电加热泡沫过滤器的减烟装置(100)包括绝缘体(111),加热泡沫过滤器(130)和收集泡沫过滤器(150)。 从内燃机排出的废气流入绝热体内。 排气通过多个排气孔排出到外部。 通过排气孔排出的废气中的有害物质通过催化作用转化成无害物质。 加热泡沫过滤器的表面涂覆有催化剂,催化剂被电加热。 收集泡沫过滤器收集通过加热泡沫过滤器排出的废气中的颗粒物质。

    • An oxidation catalyst composition for diesel engines is provided to suppress the generation of sulfate while sufficiently burning soluble organic fractions in diesel automobiles using high-sulfur fuel. An oxidation catalyst for purifying exhaust gas of diesel engines comprises: a composite support consisted of titania-silica, zeolite and alumino silicate and supported on a flow-through type substrate made from ceramic or metal; and 0.1 to 10 wt.% of at least one platinum group catalyst component, which is selected from platinum(Pt), palladium(Pd), or rhodium(Rh)-based components, and 0.1 to 20 wt.% of a vanadium(V)-based catalyst component that are supported on the composite support. The oxidation catalyst is prepared by supporting a platinum group catalyst component and a vanadium catalyst component on the composite support after wash-coating the substrate with the composite support. The oxidation catalyst is prepared by wash-coating the substrate with a composite support having a platinum group catalyst component and a vanadium catalyst component supported thereon.
