The Air Resources Board has verified the Donaldson Low NOx (LXF) Muffler System for select 2002 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 emissions less than 3.0 grams per brake horsepower-hour (g/bhp-hr), as well as were certified in California to the 0.1 g/bhp-hr particulate matter (PM) emission standard when new. The LXF 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 LXF System has been approved may be found in the Executive Order and attachment below.
