Recently, The world is faced with the very serious problems related to the increasing use of the conventional petroleum fuels. The air pollutions in big cities have been occurred by the exhaust emissions from automobiles. Many researchers have been attracted various oxygen-enriched for the measure of these problems. In this study, Oxygen-enriched air supplied to a diesel engine has significant benefits in reducing the particulate matter emission but detects in increasing the NOx. This study concluded that the oxygen-enriched and cooled-EGR might be a good measure to reduce smoke, particulate emission and NOx in diesel engine.
