Inspection methods, apparatuses, and techniques are described herein for identifying defects in a plugged honeycomb body (). The inspection apparatuses and methods herein utilize reduced distortion imaging to identify the defects in the plugged honeycomb body. Backlit and/or directly illuminated images (by e.g. first light source) of the plugged honeycomb body () can be captured (by e.g. camera) and analyzed to align (by e.g. actuators) the plugged honeycomb body () in an imaging apparatus and to identify the defects.

Imaging and inspection of plugged honeycomb body

A method for regenerating a diesel particulate filter includes elevating a temperature of a gas stream flowing into an inlet of the diesel particulate filter to greater than or equal to 450&#xb0; of the inlet of the diesel particulate filter, wherein the gas stream at the inlet of the diesel particulate filter contains an amount of NOx of equal to or greater than 300 ppm, and an amount of Oof equal to or greater than 5% volume, thereby burning the soot within the diesel particulate filter. The method also includes elevating a temperature of the gas stream flowing into the inlet of the diesel particulate filter to less than or equal to 550&#xb0; C. at the inlet of the diesel particulate filter, wherein a burn rate of soot from porous watts of the diesel particulate filter is greater than or equal to 3.8 grams/liter/hour.
