A B C D E F G H I J K L M N O P Q R S T U V W X Y Z internal combustion engine The internal combustion engine is an engine in which the combustion of a fuel (normally a fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine, the expansion of the high_temperature and high -pressure gases produced by combustion apply direct force to some component of the engine. This force is applied typically to pistons, turbine blades, or a nozzle. This force moves the component over a distance, transforming chemical energy into useful mechanical energy. The term internal combustion engine usually refers to an engine in which combustion is intermittent, such as the more familiar four_stroke and two_stroke piston engines, along with variants, such as the six_stroke piston engine and the Wankel rotary engine. A second class of internal combustion engines use continuous combustion: gas turbines, jet engines and most rocket engines, each of which are internal combustion engines on the same principle as previously described. The internal combustion engine (or ICE) is quite different from external combustion engines, such as steam or Stirling engines, in which the energy is delivered to a working fluid not consisting of, mixed with, or contaminated by combustion products. [from Wikipedia] Relationships       Parents engine Engine is a subclass of Transducer. Engines are devices for converting some form of energy resource into mechanical power. Children continuous combustion engine An Engine, such as used in a Rocket where Combustion is continuous, rather than intermittent, as in a modern automobile gas engine.   diesel engine DieselEngine is the subclass of InternalCombustionEngines that use DieselFuel as their resource.   gasoline engine GasolineEngine is the subclass of InternalCombustionEngines that use Gasoline as their resource.   intermittent combustion engine An Engine, such as found in a modern Automobile, in which Combustion is not continuous, as in a Rocket, but rather a rapid series of small Explosions.   turbine An Engine which converts the kinetic energy of a moving Liquid (typically Water) into mechanical energy.
