THE EFFECTS OF EXHAUST GAS RECIRCULATION ON EMISSIONS AND PERFORMANCE OF A SPARK IGNITION ENGINE
Abstract
The development and production of modern spark-ignition engines are very important to market and regulations requirements which demand low cost, high-performance engines with low fuel consumption and reduced emissions of pollutant. 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.
