8-9 Periodic Maintenance and Adjustment
Idle speed stepper motor
To stabilize the idle speed
Fuel injector
Inject the fuel into the cylinder
Intake temperature sensor
Inspects engine intake temperature. ECU will
automatically adjust the fuel injection
volume.
Air intake pipe pressure sensor
For testing the negative pressure of the air
intake pipe, engine has the different working
conditions, the 2 parameters- opening of air
damper and pressure of air intake determine
the engine’s working condition. The ECU will
adjust the fuel injection volume according to
different negative pressure and opening of
air damper. Adjust the engine fuel injection
volume can adjust the output power and
output torque.
Water temperature sensor
For testing cooling water temperature,
according to the temperature difference,
ECU will automatically revise fuel injection
volume, to ensure the smooth operation of
the engine at all times.
Ignition signal
Ignition signal arising from the magneto, to
provide the ECU with correct ignition timing signal.
ECU
It is the core of the EFI system, it uses a
specially designed micro computer chip as a
controller and works according to the
information it receives from sensors. The
ECU calculates to ensure accurate control of
the fuel injection volume. The ECU ensures
fuel-efficient, low emission performance of
the EFI engine.
