Abstract:
A method for estimating soot loading of a diesel particulate filter includes establishing a soot loading model for estimating soot loading of a nominal diesel particulate filter, adjusting the soot loading model for a subject filter to account for differences between the nominal filter and the subject filter, and estimating soot loading of the subject filter using the adjusted soot loading model. An engine with a diesel particulate filter is also provided.
