5.9.3.1 EFI Structure
5.9.3.2 EFI system
EFI system is composed of three subsystems.
(1)Sensors:
A sensor is a device that measures a
physical quantity and converts it into a
signal which can be read by an observer or
by an instrument. Sensors in EFI system
include:
●Intake pressure sensor
●Intake temperature sensor
●TPS
●CPS
●Water temperature sensor
●Gear sensor
● Mileage
●Oxygen sensor
●4WD-lock switch
●Overriding switch
(2)ECU:
Electronic Control Unit,the brain of EFI
system,which determines the amount of
fuel injection, ignition timing and other
parameters a engine needs to keep
running by calculating and analyzing
values provided by sensors.
(3)Actuator:
Execute the EFI instruction. Main actuators
include:
●Fuel pump
●Injector
●Ignition coil
●Idle control valve
