  • Programmed fuel injection


    Programmed Fuel Injection, or PGMFI/PGM-FI, is the name given by Honda to a proprietary digital electronic fuel injection system for internal combustion engines which injects the right amount of fuel per cylinder based on specific engine data, available since the early 1980s. This system has been implemented on motorcycles, automobiles, and outboard motors.

  • Kugelfischer


    Kugelfischer is the name for a mechanical fuel injection (MFI) pump. It was produced by FAG Kugelfischer and later by Robert Bosch GmbH Derived from diesel pumps from the early 1960s, the Kugelfischer system was a mechanical injection pump for performance vehicles. It was among the first units with manufacturer-customizable fuel delivery maps which used rpm, throttle position, temperature, and sometimes barometric pressure as inputs. This was accomplished mechanically, not electronically, using cones (irregularly shaped, two-dimensional cams) to encode the maps.

It is perhaps best known for its use by BMW in the 2000tii/2002tii (and later, the 2002 Turbo) from 1970 to 1975, the 1964–1976 Porsche 911/911S/Carrera RS/RSR/Carrera MFI, and the BMW M1 supercar from 1978 to 1981.

  • Fuel injection


    Fuel rail connected to the injectors that are mounted just above the intake manifold on a four-cylinder engine.Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. All diesel engines use fuel injection by design. Petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke. On petrol engines, fuel injection replaced carburetors from the 1980s onward. The primary difference between carburetors and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburetor relies on suction created by intake air accelerated through a Venturi tube to draw the fuel into the airstream.
