Method of determining the amount of particulate accumulated in a particulate filter










Image Number 9 for United States Patent #6941750.

A method of determining the amount of particulate accumulated in a particulate filter, is based on determining possible variations in the spatial distribution and/or physical-chemical properties of the particulate as a function of engine operating conditions and past particulate accumulation in the particulate filter. A number of reference values defining a relationship between the amount of particulate accumulated in the particulate filter and the pressure drop across the particulate filter are mapped, each of the reference values relating to a respective steady engine operating condition in which particulate is accumulated in the particulate filter. In a given engine operating condition, an operating value of the parameter is then determined as a function of the reference value of the parameter relative to the same steady engine operating condition, and of past particulate accumulation in the particulate filter.
