Corning Announces New Particulate Filter For Medium- and Heavy-Duty Clean-Diesel Vehicles; Product Reduces Emissions in Original-Equipment and Retrofit Applications

    CORNING, N.Y.--Sept. 26, 2000--Corning Incorporated , a world-leading supplier of emission-control components, today announced the Corning DuraTrap(TM) RC diesel particulate filter to enable medium- and heavy-duty diesel truck manufacturers to meet the tighter emission standards being established in countries worldwide.
    The new filter can also be retrofitted to existing medium- and heavy-duty diesel vehicles.
    The Corning DuraTrap RC diesel particulate filter promises substantial benefits over currently available cordierite filters, including improved filtration performance, lower back pressure, and significantly improved thermal durability. These improvements will make possible the design of new, more efficient, more durable diesel emission-control systems.
    The new DuraTrap RC diesel particulate filter provides consistent filtration efficiency of 90 percent or greater to help reduce soot emissions.
    The Corning DuraTrap RC diesel particulate filter also has a higher cell density (200 cells per square inch) and thicker walls (0.020 inch) compared to conventional cordierite filters. This modification in filter geometry provides a more thermally durable filter by creating a higher mass body. These features help the DuraTrap RC diesel particulate filter withstand the variable and high temperatures encountered in diesel emission system regeneration processes.
    The Corning DuraTrap RC diesel particulate filter was introduced at the second annual Clean Diesel Workshop being held in Wiesbaden, Germany, Sept. 26-28. This workshop, sponsored by Corning Incorporated, brings together diesel experts from throughout the engine and vehicle industries to discuss the latest advances in clean-diesel technology.
