ABSTRACT:
An air/fuel ratio control system monitors engine load variation for generating an engine load variation indicative data. The system includes means for integrating the engine load variation indicative data to trigger asynchronous fuel delivery when the integrated value reaches a predetermined threshold value. The integrated value is cleared simultaneously with triggering the asynchronous fuel delivery.
