DENSO Corporation, a tier 1 automotive component supplier based in Kariya, Japan, has improved the temperature detection accuracy of its newly developed diesel exhaust temperature sensor. The new sensor, which is located in front of the diesel particu-late filter (DPF) and used to control temperature for DPF regeneration, helps reduce diesel emissions and improve fuel efficiency. The product will be installed on medium and heavy duty diesel vehicles sold in the U.S. beginning later in 2009. It will also be installed in vehicles sold in Japan and Europe in 2010.
