    • PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine which can burn and remove a particulate matter in a lower temperature and shorter time as compared with a conventional one.SOLUTION: An exhaust emission control device for an internal combustion engine which is provided to an exhaust passage of an internal combustion engine and equipped with a filter for catching particulate matter in exhaust gas of an internal combustion engine, contains a catalyst carried by the filter and burning the particulate matter caught by the filter, and a liquid-spraying means for spraying at least one type of liquid selected from a group consisting of water, surfactant-containing aqueous solution, light oil and alcohol to the particulate matter captured by the filter. The catalyst contains at least one type of element selected from the group consisting of group II elements, group III elements, group VII elements, iron elements and group XI elements, and does not contain melting material. The combustion temperature of particulate matter by the catalyst is 600°C or lower in a state that liquid is not sprayed by the liquid-spraying means.
    • 要解决的问题:提供一种用于内燃机的废气排放控制装置,该排气排放控制装置可以与常规的相比在较低温度和更短的时间内燃烧和去除颗粒物质。内燃机的废气排放控制装置 发动机,其设置在内燃机的排气通路上并配备有用于捕获内燃机的废气中的颗粒物质的过滤器,包含由过滤器携带的催化剂,并且燃烧由过滤器捕获的颗粒物质, 液体喷射装置,用于将由水,含表面活性剂的水溶液,轻油和醇组成的组中选出的至少一种液体喷射到由过滤器捕获的颗粒物质中。 该催化剂含有选自Ⅱ族元素,III族元素,VII族元素,铁元素和XI族元素中的至少一种元素,并且不含熔融物质。 在液体不被喷液装置喷射的状态下,催化剂的颗粒物质的燃烧温度为600℃以下。
