  2. Internal combustion engine - Wikipedia

    en.wikipedia.org/wiki/Internal_combustion_engine

    An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high- temperature and high- pressure gases produced by combustion ...

  3. History of the internal combustion engine - Wikipedia

    en.wikipedia.org/wiki/History_of_the_internal...

    In 1798, John Stevens designed the first American internal combustion engine. In 1807, French engineers Nicéphore and Claude Niépce ran a prototype internal combustion engine, using controlled dust explosions, the Pyréolophore. This engine powered a boat on the river in France. The same year, the Swiss engineer François Isaac de Rivaz built ...

  4. Four-stroke engine - Wikipedia

    en.wikipedia.org/wiki/Four-stroke_engine

    Four-stroke engines are the most common internal combustion engine design for motorized land transport, [1] being used in automobiles, trucks, diesel trains, light aircraft and motorcycles. The major alternative design is the two-stroke cycle .

  5. Wankel engine - Wikipedia

    en.wikipedia.org/wiki/Wankel_engine

    The Wankel engine (/ˈvaŋkəl̩/, VUN-kell) is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. The concept was proven by German engineer Felix Wankel, followed by a commercially feasible engine designed by German engineer Hanns-Dieter Paschke. [1]

  6. De Rivaz engine - Wikipedia

    en.wikipedia.org/wiki/De_Rivaz_engine

    De Rivaz engine. The de Rivaz engine was a pioneering reciprocating engine designed and developed from 1804 by the Franco-Swiss inventor Isaac de Rivaz. The engine has a claim to be the world's first internal combustion engine and contained some features of modern engines including spark ignition and the use of hydrogen gas as a fuel. Starting ...

  7. Atkinson cycle - Wikipedia

    en.wikipedia.org/wiki/Atkinson_cycle

    The Atkinson-cycle engine is a type of internal combustion engine invented by James Atkinson in 1882. The Atkinson cycle is designed to provide efficiency at the expense of power density . A variation of this approach is used in some modern automobile engines.

  8. Otto engine - Wikipedia

    en.wikipedia.org/wiki/Otto_engine

    This is a video montage of the Otto engines running at the Western Minnesota Steam Threshers Reunion (WMSTR), in Rollag, Minnesota. (2min 16sec, 320x240, 340 kbit/s video) The Otto engine is a large stationary single-cylinder internal combustion four-stroke engine, designed by the German Nicolaus Otto. It was a low-RPM machine, and only fired ...

    en.wikipedia.org/wiki/Nicolaus_Otto

    This was the world's first company focused entirely on the design and production of internal combustion engines. [2] The 1864 Otto & Langen engine was a free piston atmospheric engine (the explosion of gas was used to create a vacuum and the power came from atmospheric pressure returning the piston). It consumed less than half the gas of the ...
