An animated cut away diagram of a typical fuel injector. Fuel injectors are used to spray controlled amounts fuel into an internal combustion engine. A solenoid is activated when fuel is intended to be delivered to the engine causing the plunger to become pulled toward the solenoid by magnetic force. This uncovers the valve opening allowing ...
The Renix system was used in the F series engines as fitted to the Renault 19 16V, Renault 21, Renault 25, and the Renault Espace. It is a multi-point fuel injection system, as opposed to a single-point system, with several air, throttle, and pinking sensors and an advanced computer.
Fuel is always circulating within the EUI as two of its functions, other than injection for combustion, are injector lubrication and injector cooling. Connections on UIs are by formed steel tubes. Connections on EUIs are by stainless steel-reinforced hoses. The controlled part of the injector is a solenoid-operated spill valve.
Starting with the 1986 model year, the AMC straight-4 engines used a throttle body injection (TBI) or single-point, fuel injection system with a new fully computerized engine control. [3] In addition to cycling the fuel injector (pulse-width time, on–off), the engine control computer also determined the ignition timing, idle speed, exhaust ...
EEC-III exploded view diagram. This system was used on certain 1980-83 vehicles. There were two different EEC-III modules; one for use with a feedback carburetor, and one for use with Ford's "Central" throttle-body fuel injection system. The module size and shape were approximately the same as the EEC-II and still utilized the external memory ...
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 ...
