Siemens Automotive has under development an advanced catalytic-converter module for passenger-car diesel engines that it claims will reduce nitrogen oxide (NOx) and hydrocarbon (HC) emissions up to 70%. Known as SINOx, the system uses electronics, sensors, and injection technology, along with a reducing agent, to trigger a chemical reaction that converts NOx and HC into non-toxic levels of nitrogen and water. SINOX incorporates a Siemens-developed exhaust-gas management system that consists of: the catalytic converter module, ECU, and sensors; a holding tank, mixing chamber, metering device, measuring unit, and sensor equipment for urea, the system's reducing agent; and a pump and pressure regulator. "The system uses a urea-water solution and injects it into the mixing chamber," explains George Perry, president of CEO of Siemens Automotive. "This results in a chemical reaction that releases ammonia, which, in turn, converts NOx and HC into non-toxic quantities of nitrogen and water." FAX (248) 253-2998.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
