Full-Load Time Enrichment of the Air/Fuel Ratio

DESCRIPTION AND OPERATION
The Engine Control Module (ECM) also works to ensure the enrichment of the air/fuel ratio at the time of full-load running. With the Throttle Valve opening wider, the contact point of the Throttle Valve Switch moves toward "FULL ON" position, where the Vehicle is running with fully loaded. This is signaled to the ECM. The ECM determines an appropriate injection pulse width referring to the programmed data stored in its memory unit, sending the signal to the Injector Valves to effect the most appropriate Injector Valve opening.
