Abstract

This study aimed to investigate the exergy variations of five different fuels developed for internal combustion engines. Two of these fuels were newly developed boron-added fuels. In many previous studies, only one dead state temperature was considered for exergy calculations. However, it is important to note that the dead state temperature can vary. Therefore, the impact of changing the dead state temperature on the exergy of the internal combustion engine becomes crucial. In this particular study, the exergy variations of the newly developed boron-additive fuels ES12.5 and MS12.5, as well as gasoline blended with ethanol (E12.5), gasoline blended with methane (M12.5), and pure gasoline (B100) were examined. These variations were analyzed at different dead state temperatures ranging from 273K to 298K. This study focused on examining the detailed changes in the exergy of exhaust gases emitted from the combustion process, specifically at the exhaust outlet, with respect to variations in the dead state temperature. Furthermore, the impact of the dead state temperature on various parameters commonly used in thermodynamic analyses, including Improvement potential, productivity lack, and fuel depletion ratio were investigated.. Through analysis, the study revealed significant variations in the exergy of internal combustion engines when the dead state temperature was altered. These findings emphasized the importance of considering the dead state temperature as a critical factor in understanding and optimizing the exergy performance of internal combustion engines.
