Diesels equipped with a new emission control system could meet Environmental Protection Agency standards scheduled to be phased in beginning in 2004. ORNL researchers achieved 0.05 grams per mile nitrogen oxide emissions from a light-duty diesel vehicle using a prototype nitrogen oxide adsorber and 3 parts per million sulfur diesel fuel. The system reduced the vehicle's nitrogen oxide emissions by more than 90 percent when the vehicle was run according to federal test procedures. While durability of the emissions reduction system has not been shown, results indicate that there is hope for this efficient power plant to power our future.
