Clogging extent detecting process for diesel vehicle, involves determining clogging extent as function of difference between maximum and reference temperatures, and between slopes of progression and temperatures

摘要

The process involves measuring maximum temperature obtained by the successive combustion reactions of diesel during the course of regeneration of a particulate filter (1), and raising the progression of temperature. Extent of clogging is determined as a function of the difference between maximum and reference temperatures, and between slopes of progression of temperature and reference temperature.
