method for determining the temperature of a partikelfilters, procedures to control the regeneration of the partikelfilters, and control system and particulate filter

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.
