MINNEAPOLIS, Minn. — The U.S. Environmental Protection Agency’s Office of Transportation and Air Quality approved Donaldson’s Diesel Oxidation Catalyst muffler/Spiracle crankcase ventilation filter.
The DOC muffler and crankcase filter combination dramatically reduces diesel engine emissions by 25 to 50 percent from the tailpipes and engine crankcase vents of medium and heavy-duty trucks.
Donaldson is the only company in the nation to be approved by the EPA’s rigorous Environmental Technology Verification Program. 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 continue to see growing interest in a combined system that provides substantially more reductions than a DOC muffler alone. Since up to 25 percent of emissions come from the open crankcase on diesel engines, tailpipe-only solutions ignore a big contributor to the problem,” said Steve Schmeichel, emissions general manager, Donaldson Company.
