In turning to the subject of engine heat transfer it is instructive to begin with a detailed look at where all of the fuel energy goes. If the entire engine is treated as a thermodynamic system, energy enters the system with the fuel. Air enters the system at ambient conditions and therefore, by convention, with zero energy. Under steady-state conditions, and averaged over an operating cycle, no energy is stored, and energy exits the system at the same rate it enters. In other words, all of the energy entering the engine in the fuel exits the engine at the same rate. The energy exits the system as either work, heat transfer, or with the exhaust flow.
