Transient Enrichment of the Air/Fuel Ratio

DESCRIPTION
While the Engine is warming up, the acceleration enrichment is provided for the short period when the Wide Open Throttle (WOT) Switch is moved toward "IDLE OFF" position from "IDLE", or when the intake air flow becomes high. Both the quantity of the enrichment and its working time are decreased gradually with increasing Engine temperature and are not provided in normal operating Engine temperature.
