  2. Fuel injection - Wikipedia

    en.wikipedia.org/wiki/Fuel_injection

    The term fuel injection is vague and comprises various distinct systems with fundamentally different functional principles. The only thing all fuel injection systems have in common is the absence of carburetion. There are two main functional principles of mixture formation systems for internal combustion engines: internal and external.

    en.wikipedia.org/.../Animated_Fuel_Injector

    Original Reason A large animated cut away diagram of a fuel injector. Its a fairly simple mechanical device in itself but without a visual aid it can be quite hard to understand a written description of how an injector actually works, especially if one has no mechanical inclination.

  4. Rochester Ramjet - Wikipedia

    en.wikipedia.org/wiki/Rochester_Ramjet

    The Ramjet is a continuous-flow port-injection system. Unlike later fuel injection systems that used electronics, this one is based on purely mechanical principles. The two main sub-assemblies of the system are the air meter and the fuel meter. The air meter measures airflow into the engine and manages thermostatic warmup enrichment, fuel ...

    Before electronic fuel injection showed the way forward, European engineers created radically and wonderfully complicated mechanical fuel-injection systems.

  6. Jetronic - Wikipedia

    en.wikipedia.org/wiki/Jetronic

    Electronically controlled mechanical fuel injection. The engine control unit (ECU) may be either analog or digital, and the system may or may not have closed-loop lambda control. The system is based on the K-Jetronic mechanical system, with the addition of an electro-hydraulic actuator, essentially a fuel injector inline with the fuel return.

  7. Gasoline direct injection - Wikipedia

    en.wikipedia.org/wiki/Gasoline_direct_injection

    Gasoline direct injection (GDI), also known as petrol direct injection (PDI), [1] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold).

  8. Common rail - Wikipedia

    en.wikipedia.org/wiki/Common_rail

    Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines. [1]

  9. 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 ...
