Engine works
Devices converting heat energy into motion are commonly referred to simply as engines.[4] Examples of engines which exert a torque include the familiar automobile gasoline and diesel engines, as well as turboshafts. Examples of engines which produce thrust include turbofans and rockets.
When the internal combustion engine was invented, the term motor was initially used to distinguish it from the steam engine—which was in wide use at the time, powering locomotives and other vehicles such as steam rollers. component that transforms the flow or changes in pressure of a fluid into mechanical energy.
