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-
latestofixedthe amountoffuel
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:.
Battery power supply is supplied, by way of the
controlrelay,to the injectors. When the engine
controlunit switchesONthe power transistor
within the unit and current flows to the solenoid
coil, the injectors open and fuel is injected_
