    • The invention concerns a diesel-soot filter which cleans itself, while operating, by burning off the soot and which has first honeycomb elements (9) with a relatively coarse cell structure and second honeycomb elements (10) with a relatively fine cell structure, arranged alternately behind each other, so that the soot is deposited substantially in the latter. The first honeycomb elements (9) correspond to the catalytic converters used for the removal of pollutants from the exhaust of internal combustion engines and decrease the proportion of carbon monoxide and oxides of nitrogen in the exhaust gases. The heat generated by these exothermic reactions, plus an optional auxiliary heater for the second honeycomb elements (10), enables a temperature to be reached which, in conjunction with a catalytic coating on the second honeycomb elements which lowers the ignition temperature of the soot, permits the soot to be burnt off. To provide the necessary oxygen, additional, pre-heated air is aspirated through special ducts (15). Owing to the improved thermal balance, the soot filter does not need to be located in the proximity of the engine, but may be integrated in the silencer (3 - 5). Both ceramic and metal honeycomb elements mmay be used, in the first case the catalytic layer being also designed as a thermal conductor.
    • 本发明涉及一种柴油烟灰过滤器,其在操作时通过燃烧烟灰来清洁自身,并且具有第一具有相对粗细胞结构的蜂窝元件(9)和具有相对细胞结构的第二蜂窝元件(10) 交替地彼此相邻,使得烟灰基本上沉积在后者中。 第一蜂窝元件(9)对应于用于从内燃机排气中去除污染物的催化转化器,并减少废气中一氧化碳和氮氧化物的比例。 这些放热反应产生的热量加上用于第二蜂窝元件(10)的可选的辅助加热器使得能够达到温度,其结合第二蜂窝元件上的催化涂层降低烟灰的点火温度, 允许烟灰被烧掉。 为了提供必要的氧气,通过专用管道(15)吸出额外的预热空气。 由于改善的热平衡,烟尘过滤器不需要位于发动机附近,而是可以集成在消音器(3 - 5)中。 可以使用陶瓷和金属蜂窝元件,在第一种情况下,催化层也被设计为导热体。

    • An object of the invention is to prevent or reduce deposition of urea by a simple measure in an exhaust system structure equipped with an addition device that adds aqueous urea solution to exhaust gas. An exhaust system structure for an internal combustion engine according to the invention includes an exhaust pipe connected to the internal combustion engine and an addition device located midway in said exhaust pipe to add aqueous urea solution to exhaust gas flowing in said exhaust pipe. The outer wall of a portion of the exhaust pipe on which aqueous urea solution added by the addition device impinges is in contact with the outer wall of a component of the exhaust system arranged upstream of the aforementioned portion so that the temperature of the aforementioned portion is raised.
