TURBOS BOOST THE DIESEL'S FUTURE (TURBOCHARGED DIESEL ENGINES)

Although initial costs are high, turbocharging a diesel engine reduces particulate and nitrogen oxide emissions and noise in most cases, and increases power without a fuel economy penalty. Turbocharging has not been more readily adapted by diesel car manufacturers because expensive modifications must be made to the engine in order to maintain the diesel's reliability. The rigors of turbocharging are particularly hard on the lubrication system and on various components in the cylinder head. Two automakers are currently offering turbo diesels in the U.S.: Mercedes-Benz and International Harvester. IH's Scout diesel is built by Nissan; the six-cylinder 3.2 L prechamber diesel puts out 101 hp and has a 22 mpg rating. Mercedes' 3.0 L turbo diesel is used in its larger S-class vehicle; the 1980 Mercedes 300SD diesel develops 120 hp and has a 24 mpg city and 32 mpg highway rating. Overseas, Peugeot and Mitsubishi offer turbo diesel models, and other companies are actively involved in turbo diesel research and development (Volkswagen, Audi, Chrysler, and General Motors). Elements in General Motors' diesel nitrogen oxides reduction program are listed, including modifications to the engine, the fuel system and the car.
