 Suzuki Burgman 400 - Service manual > General Description

Injection Timing Description 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. These compensations are determined according to the signals from various sensors that detect the engine and driving conditions.
