Grand Caravan L4-153 2.5L SOHC VIN K TBI (1988)
-
Allows PCM to precisely control the amount of fuel injected.
-
Atomizes fuel for more complete combustion.
-
Sprays fuel into intake manifold, above intake ports, in an even, conical pattern.
Operation
-
When an injector solenoid is energized, the plunger is retracted, lifting needle valve off seat, allowing the pressurized fuel to spray into the intake
manifold.
-
When the solenoid is de-energized spring pressure closes valve.
NOTE: Since the injector nozzle is a fixed size and fuel pressure is regulated (at 48 psi), the amount of fuel injected changes only when the amount of
time the injector is energized per cycle changes.
-
This period of time is called "injector pulse width".
