arbcombo -- Extension of Donaldson DPM Verification Posted: 01 Oct 2008 15:16:49
Extension of the Donaldson DPM Diesel Particulate Filter Muffler (DPF) system verification. The ARB extended the verification of the Donaldson DPM diesel particulate filter (DPF) muffler system with Series 6300 catalyst formulation for specific 1993 through 2006 model year diesel engines used with on-road applications operating on ultra low sulfur diesel fuel. All of these engines are four-stroke, medium and heavy heavy-duty diesel engines, including turbo-charged, mechanically or electronically injected, and are not equipped with exhaust gas recirculation. The system employs a DPF to achieve at least an 85 percent reduction (Level 3) of diesel particulate matter. Specific engine families and conditions of verification that apply may be found in the Executive Order, which may be found on the ARB website at: http://www.arb.ca.gov/diesel/verdev/verdev.htm You are receiving this single arbcombo email because you are a subscriber to or have made a public comment to one or more of the following lists: diesel-retrofit, ms-mailings.
