Because these parameters are directly related to the combustion process in an engine cylinder, many kinds of research have been achieved to identify these parameters which affect combustion efficiency and pollutant formation in this engine cylinder. In this study, a thermodynamic cycle model has been developed and used to predict the effects of Exhaust Gas Recirculation (EGR), which is used to reduce the Nitrogen Oxide (NO) in exhaust gas, on emission levels and performance of a spark-ignition engine. The model simulates full thermodynamic cycle of a spark-ignition engine and includes heat transfer, combustion, gas exchange process, thermal dissociation of water and carbon dioxide, and chemical equilibrium in engine cylinder. <br /> </p>}, number={2}, publisher={Millî Savunma Üniversitesi}
