Cummins' exhaust facility meets 2007 EPA regulations

Cummins Emission Solutions' North American exhaust aftertreatment manufacturing facility has begun producing the diesel particulate filters (DPF) that will help engine manufacturers to meet the 2007 US EPA (Environmental Protection Agency) emissions standards.

Those standards will reduce particulate matter emissions in on-highway diesel-powered vehicles by 90%, while also resulting in a significant reduction in nitrogen oxides (NOx) emission, the company says.

DPFs use 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% while also reducing hydrocarbons and carbon monoxide. The DOC optimizes the regeneration capability of the particulate filter, a critical aspect for maintaining fuel economy comparable to today's engines.
