America has yet to make up its mind about a diesel engine under the the hood of the typical passenger car.But in the European Union nations,.diesels have a more than 50 percent share of the engine market in the last two model-years of sales .Despite these impressive statistics,the diesel engine still has to over-come the U.S.car-buying public’s memory of General Motor’s(GM)dis-astrous attempt at modifying a 350-cubic-inch displacement(GID),gaso-line-powered V8 to run on diesel fuel.
While Ford,GM and DaimlerChrysler provide excellent small-displacement diesel engines as options for the European car buyer,not one has yet announced its intention to bring these clean,efficient,quiet,higher fuel efficiency engines here to the United States.
The U.S.Environmental Protection Agency’s(EPA) emissions regula-tions for diesel engines have been a big stumbling block for OMEs who want to bring in their high-tech diesel automotive power plants from Europe.That fact may be changing,however,EPA recently signaled an easing of these tough emissions standards which would permit these diesel engines to be part of the nation’s alternate fuel strategy.
For2007,Mercedes-Benz(M-B) has replaced its E320 Commonrail.Direct Injection(CDI)inline-six diesel engine with the all-new three-liter V6 CDI BLUETEC-configured engine .M-B says this diesel engie offers four-cylinder fuel economy with V8 torque.
The BLUETEC technology a comprehensive system of diesel emis-
