DaimlerChrysler Highlights Clean Diesel Technology
DaimlerChrysler offers a range of diesel passenger vehicles in Europe, where approximately 35 percent of cars are powered by diesel engines. According to a study com-missioned by the Diesel Technology Forum, the state of California alone could eliminate 20 million barrels of oil per year if it had Europe's percentage of diesel vehicles.Diesel engines have reduced NOx and particulate matter emissions an average of 90 percent since 1980 through advanced technologies such as high pressure fuel injection, pilot fuel injection, computer-controlled engine functions, and common rail technology, which supplies constant fuel pressure to electronically controlled injectors. New diesel engines also demonstrate improvements in reducing noise, vibration and harshness, and are often more durable than comparable gasoline engines. Introduction of low-sulfur diesel fuel in the future could make it possible for automakers to adapt more sophisticated emissions control technologies that would make diesel emissions comparable to gasoline engines.
