engine
Engine is a subclass of Transducer. Engines are devices for converting some form of energy resource into mechanical power.
Relationships      
Parents transducer A Device which is capable of converting one form of energy into another. Formally, a Twoport that neither stores nor dissipates, but only transfers energy between its two ports.
Children electric motorElectricMotor is the subclass of Engines that produce mechanical power from electricity.
 internal combustion engineInternalCombustionEngine is the subclass of Engines in which a heat reaction that occurs inside the engine is transformed into mechanical energy.
 outboard engineAn outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom. They are the most common motorized method of propelling small watercraft. As well as providing propulsion, outboards provide steering control, as they are designed to pivot over their mountings and thus control the direction of thrust. The skeg also acts as a rudder when the engine is not running. Compared to inboard motors, outboard motors can be easily removed for storage or repairs. [from Wikipedia]
 steam engineSteamEngine is the subclass of Engines that produce mechanical power from heat and steam pressure.
 turbineAn Engine which converts the kinetic energy of a moving Liquid (typically Water) into mechanical energy.
