Internal Combustion Engine
Any engine, either reciprocating or rotary, in which the fuel is consumed in the interior of the engine rather than outside of the engine.
Examples of internal combustion engines are diesel and petrol engines.
Steam engines are an example of an external combustion engine.
The main advantage of the internal combustion engine is the efficiency and overall size for a given power output.
- 1860 French inventor Jean-Joseph-Étienne Lenoir patented a one-cylinder engine that used kerosene for fuel.
- 1861 Alphonse Beau de Rochas patented the concept of four strokes, with the vital compression of the mixture before ignition
- 1864 Austrian inventor Siegfried Marcus built and drove a carriage propelled by a two cylinder gasoline engine.
- 1876 American George Brayton patented an internal-combustion engine that was displayed at the 1876 Centennial Exhibition in Philadelphia, Pennsylvania.
- 1876 German engineer Nikolaus August Otto built the first practical four-stroke gas engine, the most direct ancestor to today′s automobile engines.
