Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Injectors, 4 cyl.
The injectors are connected directly to the fuel rail. They are located in the intake ports in front of the inlet valves.
The injectors consist of a valve body and spray nozzle with electromagnetic armature. The valve body contains a solenoid winding and actuator for the spray nozzle. The injectors are controlled electromagnetically, opening and closing by means of electric pulses from the control module.
The injectors are of the air-cooled type. A separate passage in the intake manifold supplies air to the relevant injector. The air is directed to an annular nozzle situated round the fuel orifices. This system ensures improved atomization of the fuel.
