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.

What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
