Determining the final injection duration
The intake air volume determines the basic injection duration. However, at a given intake air vol-
ume, the volume of fuel that is required varies by the engine operating conditions such as accelera-
tion or deceleration, or by weather conditions. This system uses various sensors to precisely check
these conditions, applies compensations to the basic injection duration, and determines the final
injection duration based on the operating condition of the engine.
The fuel is cut off under conditions that do not require fuel, in order to stop the injection.
