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 ...
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.
Performance changes include twin fuel pumps (a Mustang GT's single supply pump, twice over), larger fuel injectors, a grippier and larger-diameter clutch, a larger fan, a three-row intercooler (the previous car used a double-row unit), a beefed-up Tremec 6060 six-speed with an internal oil pump, and a single-piece carbon-fiber driveshaft.
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 ...
The block was fitted with revised, taller lifter bosses to accept roller lifters, and a steel camshaft in 1985, and electronic sequential fuel injection was introduced in 1986. While sequential injection was used on the Mustang beginning in 1986, many other vehicles, including trucks, continued to use a batch-fire fuel injection system.
In March 1983, direct-port fuel injection using Bosch Jetronic LE was offered as an option on the 4.1 L engine. [28] With the release of the XF Falcon the following year, the injected 4.1 was upgraded with Ford's EEC-IV engine management system with Multi Point Electronic Fuel Injection (MP-EFI). Changes to the carburettor-based engine were ...
