Fuel injection-ignition system components
Electric injector
Injectors (1) deliver the right amount of fuel for trouble-free engine operation.
The ECU controls power supply to a winding, which creates a magnetic field attracting an armature and
causing fuel injection. Assuming that fuel properties such as viscosity and density as well as injector
delivery and pressure head -which is controlled by fuel pressure regulator- do not change over time,
the amount of injected fuel depends on injector opening time. This time is set by the control unit
according to engine operating conditions, for correct engine feeding.
