摘要:
A device is provided for the distribution of flowable additives in exhaust gas systems of an internal combustion engine, in particular for the distribution of a water/urea mixture in an exhaust gas system of a diesel engine, having an injection device in particular opening into the exhaust tract before a so-called SRC catalytic converter, with a swirl generation device being provided for the improvement of the mixing of the exhaust gas with the additive in the introduction region of the additive in the exhaust tract.

A system is provided for admixing a reducing agent to an exhaust gas flow of an internal-combustion engine. The system includes an exhaust line and a metering device for feeding the reducing agent into the exhaust line, the metering device is arranged in or on a hollow body arranged on the exhaust line. An inner volume of the hollow body is connected in an exhaust-gas-conducting manner with the exhaust line. The reducing agent is feedable by a nozzle into the hollow body. A jacket body is provided between the hollow body and the nozzle-fed reducing agent, which jacket body surrounds the reducing agent at least in areas in the inner volume. Accordingly, a depositing of reducing agent on the metering device and on the hollow body is substantially avoided.

Transparent or transparent dyed lithium aluminium silicate (LAS) glass ceramic material is provided that has an adapted thermal expansion. The material includes high-quartz mixed crystals as the predominant crystalline phase, and a thermal expansion between room temperature and 700° C. from 1.0 to 2.5·10−6/K.

The method of environmentally friendly melting and refining a glass melt of a crystallizable glass, which is used for making a lithium aluminum silicate (LAS) glass ceramic, includes the steps of providing a glass batch with a main batch composition within a lithium aluminum silicate (LAS) glass system, in which 0.1-
摘要:
The cooking panel is made from an opaque glass-ceramic material uniformly colored throughout and having keatite mixed crystals as the predominant crystalline phase. The cooking panel is made by ceramicizing a ceramicizable glass or a transparent glass-ceramic with high quartz mixed crystals as the predominant crystalline phase in a definite color location range with a brightness parameter value (L*) less than 85 and a color shade and chromaticity according to its later service and wear pattern. The cooking panel makes deposited material, such as dirt and the like, less conspicuous.
