Fuel Injector: Description and Operation
Fig. 2 Fuel Injector Location (Typical)
The injectors are positioned in the intake manifold with the nozzle ends directly above the intake valve port (Fig.2)
Fig. 3 Fuel Injector
The fuel injectors are electrical solenoids (Fig.3). The injector contains a pintle that closes off an orifice at the nozzle end. When electric current is
supplied to the injector, the armature and needle move a short distance against a spring, allowing fuel to flow out the orifice. Because the fuel is under
high pressure, a fine spray is developed in the shape of a hollow cone.The spraying action atomizes the fuel, adding it to the air entering the combustion
chamber. Fuel injectors are not interchangeable between engines.
