Fuel injection-ignition system
Operating phases
Normal operation
When the engine is warm, the unit calculates injection time and the ignition advance using the values stored in the respective
maps, in accordance with the RPM and throttle position. The calculated quantity of fuel is fed to each cylinder through the
injectors in one single sequential delivery.
Starting
When the ignition switch is turned to ON, the control unit activates the fuel pump for a few moments to pressurise the fuel supply
circuit. The throttle position and engine temperature signals are processed. When the engine is turned over by the starter motor,
the unit receives the engine RPM and timing signals that allow it to proceed with injection and ignition. To facilitate start-up,
the mixture is enriched in accordance with engine temperature During starting, the ignition advance angle is maintained at 0°
until the engine starts. When the engine starts, the ECU controls the ignition advance in accordance with the values stored in
the map and makes any necessary corrections according to the air and engine temperatures.
Acceleration/deceleration
During acceleration, the ECU makes the mixture richer for improved engine performance. Acceleration is detected by monitoring
the speed at which the rider turns the twistgrip to open the throttle. During a rapid deceleration, determined by the rider quickly
turning the twistgrip to close the throttle, the ECU makes the mixture leaner to reduce emissions and fuel consumption.
