Verification Extension for the Donaldson LNF System for On-Road Diesel Vehicles . The Air Resources Board (ARB) has completed an extension to the verification of the Donaldson Low NO2 Filter (LNF) Muffler System for select 1993 through 2006 model year diesel engines used in on-road applications. All approved engines are four-stroke, turbocharged, have certified oxides of nitrogen emissions of 3.0 grams per brake horsepower-hour (g/bhp-hr) or greater, and are certified to the 0.1 g/bhp-hr emission standard for particulate matter (PM). The LNF system employs a catalyzed pre-filter and a catalyzed diesel particulate filter with a backpressure monitor to achieve an 85 percent reduction in PM 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 which will be posted within ten days on ARB website at: http://www.arb.ca.gov/diesel/verdev/verdev.htm.
