Özet

This paper deals with exergy and exergoeconomic analyses of gasoline-hexanol and gasoline-heptanol blends as alternative additives were performed in a spark-ignition engine at a constant speed (1,600 rpm). Fuel cost rate, cost per unit of exergy for power, cost rate of total exergy loss, exergonomic factor, and relative cost difference were calculated. The lowest cost of the power acquired from the engine for G100, HEX20 and HP20 at 5 kW was $0.122/MJ, $0.656/MJ and $1.042/MJ, respectively, and the corresponding fuel cost rates were $1.07/h, $5.2/h and $8.26/h, respectively.
