What is Heat Engine? What is the working procedure and its examples?

Heat engine is a device which converts heat energy into mechanical work by exploiting the temperature difference between a hot source and a cold sink. Heat is transferred from the source to the sink, through the working substance of the engine. During this transfer, some of the heat energy is converted into work.

One of the most important things we can do with heat is to use it to do work for us. A heat engine does exactly this—it makes use of the properties of thermodynamics to transform heat into work. Gasoline and diesel engines, jet engines, and steam turbines that generate electricity are all examples of heat engines.
