          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
           combustionchamber.

          External Combustion Engine
           An external combustion engine (EC engine) is a heat engine where an
           (internal) working fluid is heated by combustion in an external source,
           through the engine wall or a heat exchanger. The fluid then, by expanding
           and acting on the mechanism of the engine, produces motion and usable
           work. The fluid is then cooled, compressed and reused (closed cycle), or
           (less commonly) dumped, and cool fluid pulled in (open cycle air engine).

                   ReciprocatingEngine
                    Areciprocating engine, also often known as a piston engine, is a heat
                    engine that uses one or more reciprocating pistons to convert pressure
                    into a rotating motion. This article describes the common features of all
                    types. The main types are: the internal combustion engine, used
                    extensively in motor vehicles; the steam engine, the mainstay of the
                    Industrial Revolution; and the niche application Stirling engine.
