arbcombo -- Conditional Verification of the Caterpillar DPF Posted: 23 Jan 2008 11:46:40
The Air Resources Board conditionally verified the Caterpillar Diesel Particulate Filter (DPF) as a Level 3 passively regenerated diesel emission control system for use with rubber-tired off-road equipment powered by certain off-road diesel engines with model years between 1996 and 2008. Approved engines are certified to a particulate matter emission level equal to or less than 0.2 grams per brake horsepower-hour, are rated to at least 175 horsepower and less than 300 horsepower, and are not equipped with exhaust gas recirculation systems. The Caterpillar DPF uses a cordierite wall-flow filter with an upstream diesel oxidation catalyst for regeneration to achieve an 85 percent reduction in emissions of diesel particulate matter. Specific conditions for which the Caterpillar DPF has been approved may be found in the conditional verification letter at http://www.arb.ca.gov/diesel/verdev/verdev.htm .
