INJECTOR
There are two injection holes in the injector mouth so the
injected fuel brarlChes eQUally in
two
directions.
Conseql.lently. fue l is injected directly to each of tha two
intake valves in each cylinder for smooth fuel intake and
improved startiflg and driveabi lity.
A high resistance type injector is used in the Non-Turbo
model and a low resistance type injector with resistor is used
in the Turbo model.
Furthermore ,
~
fue l pressure regulator to control fuel
pressure to 335kPa 148.5 psil is used on Non-Turbo models.
and a fuel pressure regulator to control fue l pressure to
300kPa 143.5 psi) is used on Turbo models
FUEL PUMP RELAY NO.2 <Turbo>
Fuel pump relay No.2 is t he relay that changes the supply
voltage to the fu el pump in 2 staps. High/Low.
The engine control unit controls the amount of fuel
discharged from the fuel pump by changing tha supply
voltage.
FUEL PUMP RESISTOR
The fual pump resistor lowers the supply
~oItage
to tha fuel
pump.
