Differences of Internal and External Combustion Engine
The difference between external and internal combustion engines is quite straightforward and is made obvious by the difference in their names. In an external combustion engine, the fuel isn't burned inside the engine. ... External engines have a working fluid that is heated by the fuel.An external combustion engine (EC engine) is a heat engine where a working fluid, contained internally, 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 main difference is where the combustion takes places. In IC engines fuel combustion takes place inside the cylinder, whereas in EC engines it takes place outside the engine cylinder. ... 3) IC engines are made of materials that are better resistant to heat and pressure than in EC engines.internal-combustion engine. An engine whose fuel is burned inside the engine itself rather than in an outside furnace or burner. Gasoline and diesel engines are internal-combustion engines, as are gas turbine engines such as turbojets. Compare steam engine .
