Injection Time (amount of injection)
The factors to determine the injection time are the basic injection time which is calculated on the basis of the engine speed and the intake manifold
pressure (amount of the intake air) and various compensations which are determined according to the signals from various sensors that detect the state of
the engine and driving conditions.
Fuel cut
Fuel injection stops (with operation of the injector prevented) when decelerating (i.e. when the throttle valve is at idle position and the engine speed is
high), so that unburned gas will not be exhausted and it starts again when above conditions are not met. Fuel injection also stops when the engine speed
exceeds about 6,800 r/min to prevent over-run which affects the engine adversely and it starts again when the engine speed reduces to less than about
6,600 r/min.
