Jeep® revealed the cleanest diesel powertrain in its class at the 2006 North American International Auto Show in Detroit. The BLUETEC Grand Cherokee is the latest engineering concept in advanced powertrain from the Chrysler Group, and it features clean-diesel technology developed by DaimlerChrysler.
The BLUETEC Jeep Grand Cherokee engineering concept demonstrates yet another possibility for ultra-clean diesel passenger vehicles in the U.S. The DaimlerChrysler BLUETEC technology will be capable of producing the cleanest diesel vehicles in the world. These next-generation innovations have the potential to meet the most stringent emissions regulations worldwide, including emissions standards in all 50 U.S. states.
BLUETEC may also include an oxidizing catalytic converter, a diesel particulate filter and an innovative system for reducing nitrogen-oxide emissions — a selective catalytic reduction (SCR) technology. SCR is an exhaust gas treatment system that converts nitrogen oxides into nitrogen and water vapor by adding ammonia as a reducing agent in a catalytic converter. These technologies can be used in various combinations depending on the specific needs of the vehicle, packaging and market requirements.
The BLUETEC Jeep Grand Cherokee Engineering Concept is built with all of these technologies. Today’s clean-diesel vehicles improve fuel economy by an average of 30 percent while reducing carbon-dioxide emissions an average of 20 percent over similar gasoline-powered vehicles. This allows BLUETEC passenger cars and light trucks to be the cleanest diesel vehicles in the world.
