8-6 Periodic Maintenance and Adjustment
③ Intake air temperature sensor/ pressure
sensor
④Duct, dampers
①Air damper degree sensor ②Idle speed step motor
③Air damper
Throttle Valve
Adjusts the inlet air flow
Idle speed step motor
Stabilizes the idle speed
Fuel Injection Tap
Injects fuel into the fuel cylinder.
Inlet temperature sensor
Monitors the air intake temperature to the
engine, the ECU automatically adjusts the
fuel injection according to the temperature.
Inlet pressure sensor
Monitors the inner pressure of the inlet line,
the operation of the engine is determined
both by the throttle valve’s angle and the
inlet line pressure. The ECU adjusts the
injectors based on the inner pressure and
the angle of the throttle valve. The output
power and torque are adjusted by changing
the injection quantity.
Ignition signal
The generator provides the ECU with the
proper ignition timing signal.
At the center of the EFI system, this model
adopts a specially designed microcomputer
chip controller, which controls the injection
quantity by calculating the information
