To inject the fuel into the cylinder.
Inlet temperature sensor
To monitor the air intake temperature to the engine, the ECU automatically adjusts the fuel
injection according to the temperature.
Inlet pressure sensor
To monitor 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 gathered by the
sensors. This enables the engine to operate with better fuel consumption and less emissions.
