Description: This image shows monolithic diesel particulate filters and experimental housings, used by Pacific Northwest National Laboratory to study reduction of diesel exhaust emissions. One of the housings has a quartz window to allow direct observation of "regeneration" of filter traps. Regeneration is the reacting away of captured soot and results in cleaning of filter traps. Understanding and controlling regeneration is essential to efficient filter trap and engine operation. Untreated, diesel engines tend to produce nitrogen oxides and particulate matter.
