Fuel Injector (Digifant II)

DIGIFANT II




Fuel Injector

Digifant II fuel injectors are electronically controlled on/off valves. A solenoid actuates a needle valve allowing fuel to be forced through the injector nozzle. All four injectors open at the same time and inject fuel directly into the intake manifold near the intake valve. Injection quantity is controlled by the amount of time the injectors stay open. Injector opening time is regulated by the E.C.U., based on inputs from the various engine sensors.

The E.C.U. grounds the injectors to control opening time. Internal resistance of each injector is approximately 14-18 ohms. When checking all four injectors, the resistance will be approximately 3.7-5.0 ohms.
