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

hightemperature and highpressure gases produced by combustion apply direct force tosome component of the engine. !he force is applied typically to pistons" turbine blades"or a nozzle. !his force mo#es the component o#er a distance" transforming chemicalenergy into usefulmechanical energy.

!he term internal combustion engine usually refers to an engine in which combustion isintermittent" such as the more familiar fourstrokeand twostroke piston engines" alongwith #ariants" such as the sixstroke piston engine and the $ankel rotary engine. Asecond class of internal combustion engines use continuous combustion% gasturbines" &et engines and most rocket engines" each of which are internal combustionengines on the same principle as pre#iously described. ''* +irearms are also a form ofinternal combustion engine.'*
