San Antonio - February 26, 2004 - Southwest Research Institute® (SwRI®) invites interested companies to join the DASL/N-TCD consortium for its third year, beginning March 18, 2004. The program will examine the lubricant effects on SCR (selective catalytic reduction) catalysts.
The Diesel
Aftertreatment Sensitivity to Lubricants (DASL), Non-Thermal Catalyst
Deactivation (N-TCD) consortium was formed in 2002 to study lubricating oil
effects on 2007 to 2010 diesel emissions control systems. The consortium applies
the science of lubricant and catalyst interactions to improve diesel emissions
control systems.
"Heavy-duty through light-duty diesel and gasoline systems will benefit from the
research performed under the consortium," said Bruce Bykowski, director of the
SwRI Engine and Emissions Research Department. "The cost-sharing attribute of
the consortium allows projects to be performed at a fraction of the cost to each
member company."
DASL is a parametric (or cause and effect) study designed to expose various diesel emissions control systems to oil combustion byproducts. The effects of lubricating oil components such as sulfur, phosphorus, zinc, calcium, boron and others are determined by measuring the deactivation of the emissions control systems as a consequence of oil exposure. N-TCD is a research study of oil-derived poisoning mechanisms.
The DASL/N-TCD consortium is structured to provide maximum flexibility to perform both kinds of studies, independently or concurrently, in the most cost-effective and timely manner.
The DASL/N-TCD consortium does not intend to duplicate work from other previous or current programs; rather it will perform work that is pre-competitive and complementary to those programs. The project advisory committee determines what work is needed to help the members develop and refine their products.
The second year of the program is nearing completion. During the first two years of the consortium, DASL/N-TCD members studied lubricant effects on catalyzed DPFs (Diesel Particulate Filter) and Continuously Regenerated Traps®. The consortium requires a minimum of five members; the actual number of members defines the scope of the work to be performed. Contracts are renewable on a yearly basis.
New members can join the third year of the consortium for $85,000.
