The Air Resources Board has granted a conditional verification for the Donaldson NR-LNF system. The conditional verification includes select off-road diesel equipment powered by off-road diesel engines manufactured from 1996 through 2010, rated between 100 horsepower (hp) and 600 hp, inclusive, and certified by ARB to a particulate matter (PM) emission level of 0.20 grams per brake horsepower-hour (g/bhp-hr) or less and to an oxides of nitrogen emission level of at least 3.0 g/bhp-hr, except those engines equipped with exhaust gas recirculation (EGR). The Donaldson NR-LNF system provides real emission reductions of PM consistent with the Level 3 plus verification category. Specific engine families and conditions for which the NR-LNF system has been approved may be found in the Executive Order and attachment below.
