Continental Automotive’s Smart NOx Sensors
Continental Automotive uses ECO PHYSICS NOx Analyzers f or testing and quality assurance in production of Smart NOx Sensors for diesel engines. Recently awarded the Automotive News PACE Award, the Smart NOx Sensor is the first on-board sensor capable of direct measurement of NOx in ppm levels. The sensor, developed in cooperation with NGK Insulators, allows vehicle and engine manufacturers like Daimler and Cummins to meet EPA 2010 and Euro V emissions require-ments. In addition to providing better fuel economy, the Smart NOx Sensor also facilitates control of after treatment systems. After treatment systems in gasoline engines includes controlling of the regeneration cycle of the NOx Storage Catalyst, while Selective Catalytic Reduction (SCR) reduces NOx by injection of ammonia into the exhaust gas.
Dr. Daniel Young, Principle Staff Physicist at Continental’s US head-quarters, uses the CLD 822 CMhr for testing in the laboratory and has recent-ly purchased a new analyzer for quality assurance on the production line. The analyzers are installed in an integrated system where calibration, sampling, and converter efficiency testing are completed with custom software. “The CLD allows us to link the measurement system calibration to our NIST tracea-ble calibration gases“, says Dr. Young.
