The authors discuss the effects of developing U.S. interest in diesel-engined cars, which is likely to be stimulated by the Federal Corporate Average Fuel Economy (CAFE) requirements for 1985 which will require light-duty vehicles to be able to attain an overall fleet average fuel consumption of 27.5 mpg. The introduction of fuel-efficient diesel-engined vehicles is seen as a way of meeting fuel consumption requirements while minimising the need to reduce vehicle size. As the additional diesel fumes might represent an increased health risk, the EPA and the Department of Energy have developed programs, described in the article, to evaluate the possible health and environmental risks. Emissions from petrol-engined and diesel-engined vehicles are compared with proposed standards for 1985 and a computer simulation model predicts the increase of diesel fuel particles over urban areas. It is concluded that although diesel emissions alone should not cause respiratory problems, when combined with emissions from other sources total air quality standards could be exceeded. (TRRL)
