Abstract :Stiff exhaust emission regulations set for limiting the air pollution caused by motor vehicles have oriented the producers and researchers to investigate new techniques to reduce exhaust emissions. The main pollutants caused by diesel engines are particle matters insert ignore into journalissuearticles values(PM);, nitrogen oxides insert ignore into journalissuearticles values(NOx);, hydrocarbons insert ignore into journalissuearticles values(HC);, and carbon monoxides insert ignore into journalissuearticles values(CO);. Among the preventive actions to keep the emissions caused by motor vehicles at a certain level are enhancing the fuel quality, preventing the pollutant formation in the engine, and developing the post-combustion emission control systems. There are many different technologies used for reducing the amount of pollutants in diesel engine exhausts. In this study, the main techniques applied for reducing these pollutants catalytically.
