Fuel is pumped from the tank to a large control valve called a fuel distributor, which divides the single fuel supply line from the tank into smaller lines, one for each injector. The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors ...
Bosch monopoint. Motronic is the trade name given to a range of digital engine control units developed by Robert Bosch GmbH (commonly known as Bosch) which combined control of fuel injection and ignition in a single unit. By controlling both major systems in a single unit, many aspects of the engine's characteristics (such as power, fuel ...
The Electrojector is an electronically controlled multi-point injection system that has an analogue engine control unit, the so-called "modulator" that uses the intake manifold vacuum and the engine speed for metering the right amount of fuel. The fuel is injected intermittently, and with a constant pressure of 1.4 kp/cm 2 (20 psi; 137 kPa ...

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 ...
It was founded in 1939 as Diesel Kiki Co., Ltd., under a Bosch license, for domestic production of fuel-injection pumps for diesel engines. [1] Originally established with an investment from Isuzu, this company was renamed ZEXEL Corp. in 1990. Diesel-Kiki entered into a joint venture in the United States with Wynns Climate Systems to begin ...
Kugelfischer injection (also called System Kugelfischer) is the name for a mechanical fuel injection (MFI) pump. It was produced by FAG Kugelfischer and later by Robert Bosch GmbH [ 1 ] Derived from diesel pumps from the early 1960s, the Kugelfischer system was a mechanical injection pump for performance vehicles.
