    • Disclosed is a two-part piston (1) for a combustion engine comprising a combustion chamber (16) in the piston head (13). The piston (1) is composed of a basic member (5) and a top part (6) that is screwed to the basic member (5). In order for the combustion pressure to act substantially upon the basic member (5), which is provided with great mechanical stability and load-bearing capacity relative to the pressure prevailing in the combustion chamber, the bottom part of the combustion chamber (16) is molded into the basic member (5), the top part (6) is configured in an essentially annular manner, and the top part (6) enlarges the combustion chamber (16) at the piston head end while delimiting the same in a radially outward direction similar to a collar (19).
    • 公开了一种用于内燃机的两部分活塞(1),其包括在活塞头(13)中的燃烧室(16)。 活塞(1)由基本构件(5)和与基座构件(5)螺纹连接的顶部(6)构成。 为了使燃烧压力基本上作用在基本构件(5)上,该基础构件(5)相对于燃烧室中的压力具有很大的机械稳定性和承载能力,燃烧室(16)的底部是 模制到基本构件(5)中,顶部(​​6)构造成基本环形的方式,并且顶部部分(6)在活塞头部端部放大燃烧室(16),同时将其径向向外 方向类似于衣领(19)。

    • A process for producing a catalyst body includes providing titanium dioxide, tungsten trioxide, vanadium pentoxide, aluminum oxide, and/or silicon oxide for the catalyst body. A kneadable and/or shapable compound is processed to form a shaped body by extrusion or by coating of a support body. The shaped body is dried and is calcined to form an active compound. The calcined shaped body is artificially aged by a final heat treatment at a temperature higher than the calcination temperature to produce a catalyst body having a high resistance to deactivation at high temperatures. The starting materials include from 65 to 95% by weight of titanium dioxide, 2 to 30% by weight of tungsten trioxide, 0 to 2% by weight of vanadium pentoxide, preferably, less than 1.5%, 0.1 to 10% by weight of aluminum oxide, and 0.1 to 10% by weight of silicon dioxide. The final heat treatment is done is at 660 to 700° C., drying is at 20 to 100° C. prior to calcination, and calcination is at 400° C. to less than 700° C.
    • 制备催化剂体的方法包括为催化剂体提供二氧化钛,三氧化钨,五氧化二钒,氧化铝和/或氧化硅。 通过挤出或涂覆支撑体来加工可捏合和/或可成形的化合物以形成成形体。 将成形体干燥并煅烧以形成活性化合物。 煅烧成形体通过在高于煅烧温度的温度下进行最终热处理而被人工老化,以产生在高温下具有高抗失活性的催化剂体。 原料包括65至95重量%的二氧化钛,2至30重量%的三氧化钨,0至2重量%的五氧化二钒,优选小于1.5重量%,0.1至10重量%的铝 氧化物和0.1〜10重量%的二氧化硅。 进行最终的热处理是在660-700℃,在煅烧之前干燥20-100℃,煅烧温度在400℃至小于700℃。

    • A motor vehicle has an internal combustion engine, a fuel tank and a tank ventilation device. The fuel tank is connected via a first and second tank ventilation lines to an intake tract of the internal combustion engine. A hydrocarbon store has first and second chambers separated by a diaphragm. The first chamber is connected in communicating fashion to the first tank ventilation line and the second chamber is connected in communicating fashion to the second tank ventilation line. Valves are arranged in the first tank ventilation line upstream and downstream of the first chamber. A valve is arranged in the second tank ventilation line between the second chamber and the intake tract.
    • 机动车辆具有内燃机,燃料箱和油箱通风装置。 燃料箱通过第一和第二罐通风管线连接到内燃机的进气道。 烃储存器具有由隔膜隔开的第一和第二室。 第一室以通信方式连接到第一罐通风管线,而第二室以第二罐通风管线连通。 阀在第一室的上游和下游设置在第一罐通风管中。 在第二室和进气道之间的第二罐通风管中布置有阀。
