Diesel Particulate Filters

A diesel particulate filter is one advanced technology option for manufacturers to use in reducing particulate matter (PM) emissions from nonroad diesel engines.

Step 1:	PM-laden exhaust enters open channels.
Step 2:	Ends of channels are blocked, forcing the exhaust through the porous walls.
Step 3:	As gasses pass through the porous filter walls, the PM is captured on the walls. Over time, the catalyst on the filter burns away the PM.
