Determining the Ethanol Content in Gasoline using Bomb Calorimetry
Authored by James F. Hauri, PhD of Roux and Benjamin J. Knurr, PhD of Assumption University
For the last century, gasoline has been the primary fuel source for internal combustion engines in many countries around the world. More recently, the petroleum-derived fuel has increasingly been mixed with combustible oxygenates, commonly ethanol. In some countries, ethanol has even become the primary or exclusive component of vehicle fuel. This switch has been done for economic and environmental reasons, but can decrease engine fuel economy. The experiment detailed here allows students to use bomb calorimetry to create a calibration curve between internal energy of combustion and ethanol content of various fuel blends.
