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.

The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
