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.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
