FUEL INJECTION CONTROL


FUEL INJECTION AMOUNT CONTROL



System Configuration Diagram


Basic fuel injection amount:
    Calculated based on the signals provided by the accelerator pedal position sensor and the crank angle sensor.
Maximum fuel injection amount:
    Calculated by applying corrections based on various sensors to the basic fuel injection amount.
DRIVE TRAIN SYSTEM PROTECTION CONTROL
    This control protects the drive train from extreme loads at the start by controlling the engine speed under the predetermined speed of 3,000 r/min.
    The engine-ECU controls the fuel injection amount at the following the conditions.

    • The transmission shift: first or reverse
    • The vehicle speed: 5 km/h or lower

LEARNING PRE-INJECTION AMOUNT







FUEL INJECTION TIMING CONTROL




System Configuration Diagram


Basic target fuel injection timing:
    Calculated based on the crank angle sensor signal and the fuel injection amount.
