Abstract
An experimental investigation was conducted to analyze the effects of stoichiometric combustion on the combustion and exhaust emissions characteristics in a single cylinder compression ignition (CI) diesel engine with common-rail injection system. In order to achieve the stoichiometric combustion, then it was carried out under various equivalence ratio which was varied from 0.63 to 1.0, which was controlled to intake air system and exhaust gas recirculation (EGR). The exhaust emissions, such as NOx and soot, were measured from emission gas analyzer at tail-pipe. The experimental results show that the trends of normalized indicated mean effective pressure (IMEP) slightly decreased according to increasing of equivalence ratio. In addition, ISNOx was dramatically reduced but ISsoot was relatively increased under increasing of equivalence ratio.
