Abstract
A fuel injection control system is directed a sequential injection type fuel injection internal combustion engine for injecting fuel to each engine cylinder at different timings. Acceleration enrichment asynchronous fuel injection is initiated in response to an acceleration demand. Acceleration enrichment is further performed for subsequent injection cycles to compensate for engine load indicative sensor signals which differ from actual engine load due to errors in an air flow meter.
