heat engine

A heat engine is a device that converts heat energy into mechanical work. It operates by taking in heat from a high-temperature source, such as burning fuel, and using part of that energy to produce motion or power, like turning a turbine or engine. The remaining heat is expelled to a cooler sink, like the atmosphere. This process follows the principles of thermodynamics and is fundamental in generating electricity and powering vehicles. Essentially, a heat engine transforms thermal energy into useful work, making it a vital component in many engines and power systems.
