BlueTec

BlueTEC is Daimler AG's marketing name for engines equipped with advanced NO reducing technology for vehicle emissions control in diesel-powered vehicles. The technology in BlueTec vehicles includes a selective catalytic reduction (SCR) system that uses diesel exhaust fluid, and a system of NOx adsorbers the automaker calls DeNO, which uses an oxidizing catalytic converter and diesel particulate filter combined with other NO reducing systems.

The BlueTEC was on the Ward's 10 Best Engines list for 2007 and 2008.
