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.
At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
