What is the heat energy released during combustion of fuel in the engine cylinder?

In the internal combustion engine, air and fuel are mixed to form a combustible mixture that is ignited and releases energy in the form of heat. While the amount of fuel trapped in the cylinder is the primary determinant of the energy content of the trapped air/fuel mixture and thus the total amount of heat that can be released, a number of secondary factors are also important such as air_Fuel ratio, density, and heating value of fuel.
