    Jet engines use the heat of combustion to generate a high-velocity exhaust as a form of reaction engine. Mechanical energy to power the aircraft's electrical and hydraulic systems can be taken from the turbine shaft, but thrust is produced by expelled exhaust gas.

  3. Engine control unit - Wikipedia

    en.wikipedia.org/wiki/Engine_control_unit

    An engine control unit ( ECU ), also called an engine control module ( ECM ), [1] is a device which controls multiple systems of an internal combustion engine in a single unit. Systems commonly controlled by an ECU include the fuel injection and ignition systems. The earliest ECUs (used by aircraft engines in the late 1930s) were mechanical ...

    Some engines suggest queries when the user is typing in the search box. A search engine is a software system that provides hyperlinks to web pages and other relevant information on the Web in response to a user's query. The user inputs a query within a web browser or a mobile app, and the search results are often a list of hyperlinks ...

    en.wikipedia.org/wiki/Automotive_engine

    The chief characteristic of an automotive engine (compared to a stationary engine or a marine engine) is a high power-to-weight ratio. This is achieved by using a high rotational speed. However, automotive engines are sometimes modified for marine use, forming a marine automobile engine .

  7. 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 ...

    en.wikipedia.org/wiki/Engine-indicating_and_crew...

    An engine-indicating and crew-alerting system ( EICAS) [1] is an integrated system used in modern aircraft to provide aircraft flight crew with instrumentation and crew annunciations for aircraft engines and other systems. On EICAS equipped aircraft the "recommended remedial action" is called a checklist.

    An illustration of several key components in a typical four-stroke engine. For a four-stroke engine, key parts of the engine include the crankshaft (purple), connecting rod (orange), one or more camshafts (red and blue), and valves. For a two-stroke engine, there may simply be an exhaust outlet and fuel inlet instead of a valve system.
