Zusammenfassung:	An internal combustion engine is run to emit an exhaust flow containing particulate. The exhaust flow passes through a filter element to remove at least a portion of the particulate from the exhaust flow. The removed particulate accumulates on the filter element. The filter element is cleaned. The cleaning includes detonating a fuel-oxidizer combination in a conduit and impacting the filter element with a wave from the detonation.
