Abstract
A method for cleaning a diesel particulate filter includes a step of coupling an acoustic generator directly to the diesel particulate filter via a support fixture. Ash deposited within the diesel particulate filter is dislodged with acoustic energy deposited by the acoustic generator. The ash may fall clear of the diesel particulate filter under the action of gravity and/or via pressurized air flow.
