Throttle Angle Influence On Injector Open Time

Idle is recognized by the low voltage value input from the potentiometer when the throttle is closed. This signal is adaptive to compensate for minor wear changes in the throttle plate position when closed. Part load is recognized by the varying voltage input value from the potentiometer while driving the vehicle at part throttle conditions. Full load enrichment is recognized from the high voltage value input from the potentiometer under full throttle conditions. The PCM modifies the ms injection time for all positions of the throttle. Considerations for other operating conditions such as vehicle speed, load and temperature, are also factored into the actual calculated time value.
