"Diesel engines for consumer vehicles in the United States in recent years have been relegated mainly to heavy-duty pickups along with the Jeep Liberty, Mercedes E-Class and a few VW models. The diesel engine just hasn't taken off here due to the relatively cheap unleaded fuel prices that Americans enjoyed. In Europe, however, diesel engines are found in 50% of new cars.

Honda has unveiled a new diesel drivetrain that it hopes to employ in its US passenger cars by 2009. It also says that the new engine passes U.S. Environmental Protection Agency (EPA) Tier II Bin 5 emissions requirements. The key to Honda's diesel cleanliness is due to an innovative new catalytic converter that uses ammonia to convert nitrogen oxide into nitrogen."
