INJECTORS

OPERATION

The iniectors are electromagnetic-valve-equipped
injection nozzles that function to inject fuel based
upon injection signals from the engine control unit:
Because the surface area of the injection ports is
fixed and because the pressure of the fuel relative
to the pressure within the manifold is also regu-
latestofixedtheamount offuel
pressure
injection by injectors is determined by the length

of time that the needle valve is open, or, in other
words, by the length of time of current flow to the
solenoid coil,

Batterv power supply is supplied , by way of the
control relay, to the injectors. When the engine
control unitswitchesONthepower transistor
within the unit ad current flows to the solenoid
coil, the injectors open and fuel is injected:.
