Exhaust aftertreatment facility makes DPFs

Cummins Emission Solutions (CES) announced that its North American exhaust aftertreatment manufacturing facility has begun producing the diesel particulate filters (DPFs) that will help engine manufacturers meet the 2007 United States Environmental Protection Agency emissions standards.

The Mineral Point manufacturing plant began in 1947 as Nelson Muffler, a four-employee operation that worked out of a small space in a former county garage. Today's facility — now about 72,000 square feet — was constructed in 1974 and expanded in 2006 to enable production of DPF systems.

The DPF uses a Diesel Oxidation Catalyst (DOC) and a diesel particulate filter to trap diesel particulate matter (PM) in the exhaust system, reducing PM emissions by 90 percent while also reducing hydrocarbons and carbon monoxide.

CES also is producing Selective Catalytic Reduction (SCR) systems in the United Kingdom and South Africa to enable its European medium- and heavy-duty vehicle customers to meet Euro IV and V emissions levels.
