A polymer (Greek , "many" + , "parts") is a large molecule, or macromolecule, composed of many repeated subunits.

Because of their broad range of properties, both synthetic and natural polymers play an essential and ubiquitous role in everyday life.

Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function.

Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers.

Their consequently large molecular mass relative to small molecule compounds produces unique physical properties, including toughness, viscoelasticity, and a tendency to form glasses and semicrystalline structures rather than crystals.

An internal combustion engine (ICE) is a heat engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit.

In an internal combustion engine the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.

The force is applied typically to pistons, turbine blades, rotor or a nozzle.

This force moves the component over a distance, transforming chemical energy into useful mechanical energy.

A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

An air compressor is a specific type of gas compressor.

A reciprocating engine, also often known as a piston engine, is typically a heat engine (although there are also pneumatic and hydraulic reciprocating engines) 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.

Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.
