Donaldson engine filter earns ARB approval
Dec 1, 2002 12:00 PM
Donaldson Co Inc has received Level 1 Verification from the California Environmental Protection Agency's Air Resources Board (ARB) for its Diesel Oxidation Catalyst (DOC) muffler and Spiracle crankcase ventilation (CCV) filter. The DOC muffler and Spiracle CCV filter combination reduces diesel engine emissions from tailpipes and engine crankcase vents of medium- and heavy-duty trucks and school buses.
ARB approval enables Donaldson to sell the combination on a retrofit basis to help California vehicle operators meet state pollution control requirements and limit diesel engine emissions.
Under ARB's Diesel Risk Reduction Plan (DRRP), about 1.25 million diesel engines in California are candidates for retrofitting with technology like Donaldson's. Such technology is designed to reduce emissions of diesel particulate matter. The combined DOC muffler/Spiracle CCV filter system reduces engine particulate matter emissions by 26% to 50%, meeting ARB Level 1 standards requiring greater than 25% reduction.
