英文摘要	The objective of this study is to investigate the effect of the CO2 mole fraction in the composition of simulated-EGR on the characteristics of combustion and exhaust emissions in a CI engine. To achieve this, the equivalence ratio was fixed at 0.73, while the CO2 mole fraction was varied from 0 to 10%. The wall interaction model was used based on the Mundo-Sommerfeld model. In addition, the results of peak cylinder pressure, ignition delay, IMEP, NO distributions, and soot distributions were compared. The ignition delay was longer and the peak cylinder pressure was decreased with the increasing CO2 mole fraction because the evaporation of the injected fuel deteriorated. Moreover, when the CO2 mole fraction was increased to 5%, the ISNO values decreased to 55% owing to the high specific heat of CO2. Furthermore, the ISSoot values increased by 10% because the oxidation of soot does not occur well by low temperatures. The Korean Society of Mechanical Engineers.
