Fuel Injector Valves (R50)

Fuel Injector Valves (R50)

Function
The fuel injector valves have a small solenoid coil that ensures fine atomization during fuel injection. The engine control module sends a signal to the fuel injector valve to activate the solenoid coil, raising the needle from the valve base. The fuel is injected in the intake pipe. The quantity of injected fuel is controlled by means of a PWM signal.

Installation Location
The fuel injector valves are located on the intake pipe.

Failure
If one or more fuel injector valves should fail, the following symptoms occur: poor running characteristics; misfiring; the engine does not start. The MIL lights up.
