UNCOMMON PERFORMANCE

摘要

More than 40 percent of the new cars sold in europe last year were powered by a diesel engine. Betting that the diesel market will grow here too, volkswagen, audi and mercedes-benz all plan to launch new diesel engines in the united states starting in 2005. Using low-sulfur diesel fuel that's expected to become available everywhere in 2006, those vehicles will be ready for strict new diesel emissions standards that take effect here and in Europe over the next few years. A big part of the reason these engines run so clean is that they are equipped with electronically controlled direct fuel injection, in which the fuel is injected directly into the combustion chamber instead of into a prechamber in the cylinder head.
