Abstract

A diesel particulate filter of a motor vehicle is cleaned of diesel particulate material like ash and possibly soot, typically using equipment already available in a service shop following the method and diesel particulate filter cleaning apparatus of the invention. The diesel particulate filter cleaning apparatus has an air chamber that is coupled to a vibrator and is attached to the diesel particulate filter. The vibrator vibrates the air chamber and the diesel particulate filter to dislodge the diesel particulate material. Air is introduced into the air chamber and into the diesel particulate filter to further remove the diesel particulate material from the diesel particulate filter.
