At the 2002 SAE show in Detroit last March, Southwest Research Institute announced it is forming a consortium for investigating the potential of common lubricating oils to degrade and poison emissions control systems for diesel and gasoline engines. Diesel Aftertreatment Sensitivity to Lubricants, Non-Thermal Catalyst Deactivation (DASL/N-TCD) is a combination of two research projects. "Both will benefit from the research performed under the new consortium," says Bruce Bykowski, assistant director of the Institute's Emissions Research Department. The DASL portion is a parametric study designed to expose diesel emissions-control systems to oil combustion by-products. Researchers measure the deactivation of the emissions control systems as a consequence of oil exposure to determine the effects of lubricating oil components such as sulfur, phosphorus, zinc, and calcium. The N-TCD portion of the consortium explores the mechanisms of emission control system deactivation as a result of oil exposure. Any companies interested in joining the consortium should contact Bykowski at the Emissions Research Dept., Southwest Research Institute, P.O. Drawer 28510, San Antonio, Texas 78228-0510.

A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
