Abstract

A method for regenerating a diesel particulate filter () in the exhaust system () of an engine (). When a request to regenerate the device is issued, a control system () operates the engine to begin conditioning exhaust. The conditioning process comprises a warming phase that occurs prior to initiation of regeneration and a heating phase during which regeneration can occur. During the process, data related to the warming phase and the heating phase is evaluated. The engine is operated to terminate the process prior to having reduced the amount of trapped particulate matter to a target amount when evaluation of the data discloses that the process should be terminated.
