Abstract
During starting of an engine, enrichment correction according to engine starting enrichment is executed. After starting of the engine, enrichment correction is transferred gradually with the lapse of time from starting enrichment to normal warm-up enrichment. The transfer speed from starting enrichment to normal warm-up enrichment is changed depending upon whether a throttle valve is in an idle position or not.
