Heat content of gasoline
WebThe energy content of ethanol is lower than that of gasoline. The heating value of ethanol is around 27 MJ/kg, in volumetric terms around 21 MJ/l, which is only 65% of the volumetric energy content of gasoline. This leads to higher volumetric fuel consumption with ethanol compared to gasoline. WebGenerally, the heat of combustion can be expressed as the following: ΔH c ° = - x ΔH f ° (CO 2 ,g) - y ΔH f ° (H 2 O,l) - z ΔH f ° (Z) + n ΔH f ° (X) + m ΔH f ° (O 2 ,g) where ΔH c ° : heat of combustion at standard conditions (25°C and 1 bar) ΔH f ° : heat (enthalpy) of formation at standard conditions (25°C, 1 bar)
