Light off temperatur katalysator

WebDamit der Katalysator hoch effizient arbeitet, ist es notwendig, dass er möglichst kurz nach Start des Motors seine volle Leistung entfaltet. Dies bezeichnet die sogenannte Light-Off-Temperatur – ab dann ist der Katalysator aktiv. Die Light-Off-Temperatur spielt auch für das Alterungsverhalten des Katalysators eine Rolle. WebFor light-duty vehicles, DEF refill intervals typically occur around the time of a recommended oil change, while DEF replenishment for heavy-duty vehicles and off-road machines and equipment will vary depending on the operating conditions, hours used, miles traveled, load factors and other considerations.Typically, DEF consumption is around 3% ...

WebTranslations in context of "seine Light-Off-Temperatur" in German-English from Reverso Context: Der Abgasbrenner (34) kann abgeschaltet werden, wenn zumindest einer der beiden Drei-Wege-Katalysatoren (26, 28) seine Light-Off-Temperatur erreicht hat. WebThe catalyst light-off is the minimum temperature necessary to initiate the catalytic reaction. Due to the gradual increase of the reaction rate, the above definition is not very precise. By a more precise definition, the light-off temperature is the temperature at which conversion reaches 50%. That temperature is frequently denoted T 50. When ...
