a device that turns heat energy into mechanical work.

A machine that operates by taking heat from a hot place, doing some work with that heat, and then exhausting the rest of the heat into a cool place. The internal combustion engine of a car is an example of a heat engine.

An engine that converts heat to mechanical energy.

any engine that makes use of heat to do work

a current or wind pattern the cycles heat energy in a convection cycle

a cyclic process that absorbs heat and does work on the surroundings

a cyclic process that absorbs heat from a heat bath and converts it into work

a device for convertingheat into mechanical work and analysis of the Carnot heatengine provides the necessary relationships we seek

a device that converts heat into work

a machine that produces work from heat

a machine that turns heat energy into work

an engine that uses heat to produce mechanical work by carrying a working substance through a cyclic

a thermodynamic system that can undergo a sequence of transformations which ultimately return it to its original state

A device which utilizes a temperature gradient to extract exergy from the higher temperature thermal mass.

A device that produces mechanical energy directly from two heat reservoirs of different temperatures. A machine that converts thermal energy to mechanical energy, such as a steam engine or turbine.

(Same as heat transfer.) A device for producing work by virtue of a temperature difference. The atmosphere may be considered such a device. See Carnot engine.

A heat engine is a physical or theoretical device that converts thermal energy to mechanical output. The mechanical output is called work, and the thermal energy input is called heat. Heat engines typically run on a specific thermodynamic cycle.
