Siemens Automotive has under development a second-generation, common rail system for high-pressure diesel fuel injections. The technology has as its goal the reduction of nitrous oxide (NOx) emissions and the noisy operation of diesels. High-pressure fuel injection resulting from the common rail (CR) technology is said to be a key to better diesel spray atomization, improved fuel/air mixing, and more efficient combustion of fuel in engine cylinders. The system incorporates piezohydraulic valve technology to precisely regulate the high-pressure injection of the fuel. The modular design incorporates the rail, valves, fuel injectors, sensors, and actuators into a single package that, according to Klaus Eggers, Siemens project leader for diesel systems, "will provide design flexibility and cost savings." Siemens engineers say piezohydraulic valves react up to four times faster than solenoids currently used, responding to voltage pulses within 0.1 msec. FAX (248) 253-2998.
Most cyber attacks could be avoided by adopting a list of Critical Security Controls that were created by the Center for Internet Security. That’s the message from Steve Mustard of the Automation Federation.
George Leopold's talk at last week's Design & Manufacturing Minneapolis helped restore astronaut and engineer Gus Grissom's role in the beginnings of NASA, and outlined how Grissom played a pivotal role in winning the Space Race.
