It is, however, important to devise heat engines which can function adaptively, in particular when the engine is a quantum system and the baths are subject to fluctuations.

Since engines work by burning fuels to release heat, they're sometimes called heat engines. The process of burning fuel involves a chemical reaction called combustion where the fuel burns in oxygen in the air to make carbon dioxide and steam.

What is a heat engine? how does an engine power a machine? types of engines.
A thermodynamic cycle consists of a linked sequence of thermodynamic processes that involve transfer of heat and work into and out of the system, while varying pressure, temperature, and other state variables within the system, and that eventually returns the system to its initial state. In the process of passing through a cycle, the working fluid may convert heat from a warm source into useful work, and dispose of the remaining heat to a cold sink, thereby acting as a heat engine.

In engineering and thermodynamics, a heat engine converts heat energy to mechanical work by using the temperature difference between a hot source and a cold sink. Heat is transferred from the source, through the working body of the engine, to the sink, and in this process some of the heat changes into work by using the qualities of the gas or liquid inside the engine.

Therefore, both (reversible) heat engines have the same efficiency, and we conclude that: all reversible engines that operate between the same two heat reservoirs have the same efficiency. This is an important result because it helps establish the clausius theorem, which implies that the change in entropy is unique for all reversible processes:.
