Verfahren zum Ermitteln der Innentemperatur eines Partikelfilters, Verfahren zur Steuerung der Regeneration des Partikelfilters, sowie Steuerungssystem und Partikelfilter

摘要

The method involves measuring entrance and exit temperatures (Te, Ts) of gas at a filter. Internal temperature (Ti) of the filter particles is then calculated by using a formula: Ti=axTe + (1-a) x Ts, where the coefficient a is the function of difference between entrance and exit temperatures and is stored in a table. Independent claims are also included for the following: (a) a process for controlling the regeneration of particulate filter; (b) a system for controlling regeneration of particulate filter; and (c) a particulate filter.
