Abstract:
The invention relates to a method for the production of a honeycombed body (4) and to a honeycombed body (4) with channels (5), wherein the walls (8) of said honeycombed body (4) are made of ceramic. The honeycombed bodies (4) can be produced from a first material that is plastic deformable and subsequently hardenable, wherein the first material is applied by layers in a predetermined manner and then hardened. The first material and at least a second material form a predetermined layer on the honeycombed body, said second material being an electrically conductive material while the second material is non-electrically conductive.
Abstract:
The exhaust system of a diesel engine includes components such as a turbocharger and an exhaust manifold which can have very high internal temperatures (e.g., any surface having a temperature above 135°C). In accordance with the invention the components subject to the high temperatures are coated with at least a first layer of thermally insulating material and a second layer overlying the first layer to provide surface protection. So coated, the temperature of the outer coated surfaces of these components is brought below an undesirably high level. Also, selected ones of the components may be water cooled and/or have a fitted jacket and/or be placed within an explosion proof enclosure. The input fuel line may also include a magnetic explosion proof fuel economizer to control the combustion process and reduce the internal temperature.
Abstract:
Kraftfahrzeug (1), umfassend wenigstens ein Antriebsaggregat (2), wenigstens eine Bremsvorrichtung (3) sowie wenigstens eine sich bei Betrieb des Antriebsaggregats (2) und/oder der Bremsvorrichtung (3) erwärmende Komponente, wobei die Komponente wenigstens ein Warnmittel (7a, 7b) umfasst, welches bei Überschreiten einer komponentenspezifischen Grenztemperatur durch die Komponente zur Ausgabe einer optischen Warninformation ausgebildet ist und/oder bei Vorliegen einer eine Überschreitung einer komponentenspezifischen Grenztemperatur betreffenden Information (I) zur Ausgabe einer optischen Warninformation ansteuerbar ist.
Abstract:
A temperature sensor (10) includes temperature detecting means and at least one of a catalyst and an adsorbent applied to the surface of the temperature detecting means. At least one of the catalyst and the adsorbent catalyzes an exothermic reaction of a reactant in gas on the temperature detecting means. A temperature that is increased by the exothermic reaction is detected by the temperature detecting means. The catalytic efficiency for the exothermic reaction of at least one of the catalyst and the adsorbent is reduced by sulfur poisoning. The temperature sensor (10) is disposed upstream of an exhaust purification system (30). Accordingly, it is determined that the temperature sensor is subjected to sulfur poisoning if the temperature detected by the temperature sensor is below a prescribed temperature.
