It can be observed that the trend for BSFC is as follows: ethanol/RP-3 > n-propanol/RP-3 > gasoline, which is inversely related to their LHV. A lower LHV requires more fuel to achieve the same output power, meaning that alcohol fuels have lower energy density and, consequently, higher BSFC [46]. The LHV of ethanol/RP-3 is lower than that of n
