DENSO Corporation, a leading global supplier of advanced technology, systems and components, has improved the temperature detection accuracy of its newly developed diesel exhaust temperature sensor. The new sensor is used to control temperature for diesel particulate filter (DPF) regeneration, and helps reduce harmful diesel emissions and improves fuel efficiency. The product will be installed on heavy duty and medium duty diesel vehicles sold in the U.S. in Fall of 2009. It will also be installed to vehicles sold in Japan and Europe in 2010.

To improve the sensor’s temperature accuracy, the company developed a vibration-resistant structure with an anti-resonance pipe to support the probe at its optimal position. Also, the sensor is equipped with a newly developed thermistor, which improves detection accuracy to plus or minus 10 degrees Celsius. With the improved temperature detection performance, the new sensor helps regenerate DPFs more efficiently, resulting in cleaner emissions, as well as increased fuel efficiency due to less fuel required in the DPF regeneration process.
