arbcombo -- Verification Extension to the Donaldson LNF
Posted: 28 Oct 2009 16:16:01
Verification Extension to the Donaldson LNF System for On-road Applications. The Air Resources Board has extended the verification of the Donaldson Low NO2 (LNF) Muffler System to select 1993 through 2006 model year diesel engines used in on-road applications. All of these engines are four-stroke, turbocharged, and have certified oxides of nitrogen (NOx) emissions of 3.0 grams per brake horsepower-hour (g/bhp-hr) or higher, as well as were certified in California to the 0.1 g/bhp-hr particulate matter (PM) emission standard when new. The LNF System employs a catalyzed pre-filter and a catalyzed diesel particulate filter with a back pressure monitor to achieve an 85 percent reduction in particulate matter emissions, qualifying it for Level 3 plus verification. Specific engine families and conditions for which the LNF System has been approved may be found in the Executive Order found in the Executive Order which will be posted within ten days on the ARB website at: http://www.arb.ca.gov/diesel/verdev/verdev.htm .
