Corning Incorporated announced today that it will begin supplying a new, advanced cordierite diesel particulate filter to light-duty diesel vehicle manufacturers. Compared to traditional cordierite, Corning's monolithic DuraTrap® AC filters offer low pressure drop to help reduce fuel consumption and increase the power rating. They also offer improved thermal durability and high-filtration efficiency.
DuraTrap AC filters are targeted to be the first cordierite filters used in large-scale for diesel passenger cars. They are optimized for use in light-duty diesel vehicles that have new and advanced regeneration systems.
“With more than thirty years of experience working with cordierite and a deep understanding of emissions control technology, we were able to develop an advanced cordierite filter that, we believe, has unique properties and performance capabilities for the light-duty diesel market,” said Thomas R. Hinman, vice president and general manager, Diesel Technologies. “The early response from global diesel auto manufacturers on our new DuraTrap AC filter has been extremely positive and we are continuing to collaborate with our customers regarding future applications for this product.”
DuraTrap AC filters offer a unique performance combination of relatively high-soot-mass limit with a low pressure drop, compared to traditional cordierite. The filter’s low pressure drop allows for integrated functionality in catalyzed-soot filter applications. In addition, the new filter offers outstanding thermal characteristics and a wide operating window. DuraTrap AC’s high-filtration efficiency will help light-duty auto makers to meet the increasingly stringent Euro V emissions regulations.
Corning will begin manufacturing and supplying DuraTrap AC filters in the first half of 2007. This is the second filter for light-duty diesel applications that Corning has launched. In 2005, Corning introduced DuraTrap® AT filters, which are being used by leading auto makers for light-duty diesel applications as an effective alternative to systems designed for silicon carbide.
Corning invented an economical, high-performance cellular ceramic substrate in the early 1970s that is now the standard for catalytic converters worldwide. In 1978, Corning developed the cellular ceramic particulate filter to remove soot from diesel emissions.
