  2. Common rail - Wikipedia

    en.wikipedia.org/wiki/Common_rail

    Diesel fuel injector as installed in a MAN V8 Diesel engine. Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).

  3. Injection pump - Wikipedia

    en.wikipedia.org/wiki/Injection_pump

    Inline diesel injection pump. Earlier diesel pumps used an in-line layout with a series of cam-operated injection cylinders in a line, rather like a miniature inline engine. The pistons have a constant stroke volume, and injection volume (i.e., throttling) is controlled by rotating the cylinders against a cut-off port that aligns with a helical ...

  4. Unit injector - Wikipedia

    en.wikipedia.org/wiki/Unit_injector

    Early Lucas electronic diesel unit injector. A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component. The plunger pump used is usually driven by a shared camshaft. In a unit injector, the device is typically lubricated and ...

  5. Unit pump - Wikipedia

    en.wikipedia.org/wiki/Unit_pump

    The Unit Pump system [1] is a modular high-pressure diesel injection system, which is closely related to the unit Injector system, and is designed for use in commercial vehicle diesel engines. [2] The systems use an individual injection pump mounted on the engine block for each cylinder so it is primarily designed for OHV or "cam in the block ...

  6. Fuel injection - Wikipedia

    en.wikipedia.org/wiki/Fuel_injection

    All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138 ) became available in the late 1930s and early 1940s, being the first fuel ...

  7. Diesel engine - Wikipedia

    en.wikipedia.org/wiki/Diesel_engine

    1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).

  8. BMW M57 - Wikipedia

    en.wikipedia.org/wiki/BMW_M57

    The injection pressure is 1,350 bar (19,600 psi) [2] in the non TÜ engine, whilst all other engines use a pressure of 1,600 bar (23,000 psi). [2] For fuel injection, magnetic injectors are used, except from the TÜ2 OL and TOP engines, which make use of piezo injectors. [2]

  9. M-System - Wikipedia

    en.wikipedia.org/wiki/M-System

    The elevated temperature then causes the fuel film to vaporise and combust. Regular Diesel engines mix air and fuel during injection by creating a high fuel velocity with high injection pressure. In M-System engines however, mixing air and fuel takes place after injection. Due to the low velocity of the fuel vaporising from the combustion ...
