An engine powered by fuel ignited (by either spark or compression) inside a cylinder.

International Cryptographic Experiment

a heat engine in which combustion occurs inside the engine rather than in a separate furnace; heat expands a gas that either moves a piston or turns a gas turbine

Internal combustion engine. Engine does that converts the energy contained in the fuel inside the engine into motion. Combustion engines use the pressure created by the expansion of the gases to do mechanical work.

See internal combustion engine.

internal combustion engine. An engine that works on power released by vaporized fuel and air burning inside the engine itself, rather than on an outside source of combustion as, for example, a steam engine does.

International Chemical Environment (As part of Responsible Care, coopeartive programme to prevent transport incidents)

Internal Combustion Engine. an engine in which both the heat energy and the ensuing mechanical energy are produced inside the engine

International Collaborative Effort

An acronym for internal-combustion engine.
