Recently, regulation for exhaust emissions of vehicles has been stronger. But lots of researches indicated that there is difference in exhaust emission between chassis dynamometer test and real driving test. Especially, diesel engine emits high level of NOx emission compared to gasoline engine and unregulated emissions able to harmful to human body due to its inherent operation principle. In this study, regulated and unregulated emissions from Euro 5 light-duty diesel vehicle during real drive test are analysed and engine control characteristics focussed in exhaust gas recirculation (EGR) are reviewed. Real driving emissions are compared to chassis dynamometer tests and unregulated emissions are quantified to notice how much emissions are emitted under high temperature and air-conditioner on/off condition.
