ughout the world concern over pollution is mounting. In many industrial countries the automobile or more specifically the internal combustion engine has been singled out as a major contributor to atmospheric pollution problems. As a result legislative bodies have acted to impose limits on pollutants emitted from gasoline powered vehicles. The purpose of this discussion is to review these automotive emissions regulations; the changes required in engines and fuels in order to meet emissions codes;and the impact of reduced automotive emissions on the air pollution problem. Much of the material presented relates to developments in the United States . However air quality is not confied by national boundaries. Therefore we believe the information presented will be of interest to those in Japan who are involved either directly or indirectly with automotive air pollution control.
