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. |
