  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.

  3. 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).

  4. Jetronic - Wikipedia

    en.wikipedia.org/wiki/Jetronic

    Mechanical fuel injection, 'K' stands for German: "Kontinuierlich", meaning continuous.Commonly called 'Continuous Injection System (CIS) in the USA. K-Jetronic is different from pulsed injection systems in that the fuel flows continuously from all injectors, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi).

  5. Manifold injection - Wikipedia

    en.wikipedia.org/wiki/Manifold_injection

    Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine.

  6. 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 ...

  7. Programmed fuel injection - Wikipedia

    en.wikipedia.org/wiki/Programmed_fuel_injection

    Programmed Fuel Injection, or PGMFI/PGM-FI, is the name given by Honda to a proprietary digital electronic multi-point injection system for internal combustion engines. It has been available since the early 1980s. This system has been used in motorcycles, automobiles, and outboard motors.

  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. Stratified charge engine - Wikipedia

    en.wikipedia.org/wiki/Stratified_charge_engine

    Since fuel is directly injected inside the combustion chamber, it never gets a chance to wash any contaminants behind the valves. This results in excessive carbon build up over time, hindering performance. Some engines (like Toyota's Dynamic Force engines) combine direct injection with traditional multi port fuel injection to ameliorate this ...
