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.
