Fuel Injector: Description and Operation
Fuel Injector (TBI 220)
Fuel Injector (TBI 295)
The fuel injectors are solenoid activated, controlled by the PCM. The PCM turns on the solenoids, which lifts a normally closed ball off a seat. Fuel,
under pressure, is injected in a conical spray pattern at the walls of the throttle body bore above the throttle valve.
The fuel that is not used by the injectors passes through the pressure regulator before being returned to the fuel tank.
