The internal combustion engine is a heat engine in which combustion occurs in a confined space called a combustion chamber.
Combustion of a fuel creates high temperature/pressure gases, which are permitted to expand.
The expanding gases are used to directly move a piston, turbine blades, rotor(s), or the engine itself thus doing useful work.
Internal combustion engines can be powered by any fuel that can be combined with an oxidizer in the chamber.
