WebThe efficiency of a heat engine relates how much useful work is output for a given amount of heat energy input. From the laws of thermodynamics : where is the work extracted from the engine. (It is negative because work is done by the engine.) is the heat energy taken from the high-temperature system (heat source). WebThese quantities express the heat energy of the fuel in heat and work units, respectively. The ratio of useful work done by an engine to the heat energy of the fuel it uses, expressed in work or heat units, is called the thermal efficiency of the engine.
