Fuel Injector: Description and Operation
1999 FUEL INJECTORS
Fuel Injector
The fuel injectors are 12 ohm electrical solenoids. 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 2 streams. The spraying action atomizes the fuel, adding it to the air entering the
combustion chamber. The injectors are positioned in the cylinder heads. Fuel injectors are not interchangeable between engines.
Fuel Injector Location - Typical
The injectors are positioned in the cylinder heads with the nozzle ends directly above the intake valve port.
