Exergetic cost analysis and sustainability assessment of an Internal Combustion Engine
This study deals with exergy cost analysis and sustainability assessment of a diesel engine, which runs with diesel no. 2 and two different biodiesel fuels at 1400 1/min test speed. Maximum total cost per exergy flow input rate and total exergy cost are found to be 12.5549 $/kW•year and 1728.312 $/year for one of the biodiesel fuels, respectively, while minimum values of these costs are determined to be 8.7832 $/kW•year and 1215.509 $/year for the diesel no. 2 fuel, respectively. Furthermore, sustainability index (SI) rates and exergetic efficiencies of biodiesel fuels are higher than those of diesel no. 2 fuel.
