INJECTION TIME (INJECTION VOLUME)
The factors to determine the injection time include the basic fuel injection time which is calculated on the
basis of the intake air pressure, engine speed and throttle opening angle, and various compensations which
are determined according to the signals from various sensors that detect the engine and driving conditions.
