Consider an internal combustion engine like that used in automobiles. The most common fuel used here is gasoline which is a mixture of hydrocarbons, and an octane rating is given for standardization. Therefore, we will approximate gasoline as being composed of the hydrocarbon, octane, C8H18. Another fuel that is common in racing applications is nitromethane, CH3NO2, used in top fuel dragsters. Let’s consider the combustion of each fuel with oxygen in an internal combustion engine. Let the 8-cylinder engine displacement...
