Donaldson Co. Inc. said the Environmental Protection Agency's Office of Transportation and Air Quality has approved Donaldson's Diesel Oxidation Catalyst
(DOC) muffler and Spiracle crankcase ventilation filter.
The DOC muffler and crankcase filter combination reduces diesel engine emissions by 25 to 50% from the tailpipes and engine crankcase vents of medium and heavy-duty trucks and buses.
Donaldson is the only company in the nation to be approved by the EPA's rigorous Environmental Technology Verification Program, according to the Minneapolis-based firm. It will enable Donaldson to offer its DOC muffler and crankcase filter solution for retrofitting a broad range of engine/vehicle combinations manufactured since 1991.
"We are extremely pleased to receive EPA approval for our diesel emission reduction system," said Steve Schmeichel, emissions general manager for Donaldson. "We continue to see growing interest in a combined system that provides substantially more reductions than a DOC muffler alone. Since up to 25% of emissions come from the open crankcase on diesel engines, tailpipe-only solutions ignore a big contributor to the problem. Donaldson is the only approved company offering the combined crankcase/tailpipe approach."
Donaldson's DOC muffler and Spiracle products are available through many engine and heavy-duty truck dealers and distributors.
