Compensations Content
Fuel injection compensation Compensation is made according to the pressure
difference between atmospheric pressure and
manifold absolute pressure. The greater the
difference in pressure, the shorter the injector drive
time.
Battery voltage compensation Compensation is made depending on battery
voltage. The lower the battery voltage, the greater
the injector drive signal time.
Learning value for fuel compensation Compensation amount is learned to compensate
feedback of heated oxygen sensor. This allows
system to compensate in accordance with engine
characteristics.
[Fuel limit control during deceleration]
ECM limits fuel when decelerating downhill to prevent excessive
rise of catalytic converter temperature and to improve fuel
efficiency.
[Fuel-cut control when over-run]
When engine speed exceeds a prescribed limit (7,500 r/min),
ECM cuts fuel supply to prevent overrunning and thus protect
the engine. Also, if engine speed exceeds 4,000 r/min for 15
seconds while vehicle is stationary (no load), it cuts fuel supply
to protect the engine.
IGNITION TIMING AND CONTROL FOR CURRENT CARRYING TIME
M21302000050USA0000010000
Ignition timing is pre-set according to engine driving
conditions. Compensations are made according to
pre-set values depending on conditions such as
engine coolant temperature, battery voltage etc. to decide optimum ignition timing. Primary current
connect/disconnect signal is sent to the power
transistor to control ignition timing. Ignition is done in
sequence of cylinders 1, 2, 3, 4, 5, 6.
