Abstract
A fuel supplying system used in engine starting includes throttle valve means disposed in an intake air passage and metering valve means disposed in a fuel passage which extends from a fuel reservoir to a space of the intake air passage downstream from the throttle valve means. In order to obtain a required air-fuel ratio of a mixture determined in accordance with data representing states of an engine, in the fuel supplying system an opening degree of the throttle valve means which have a response delay is held constant and an opening degree of the metering valve means is adapted to be changed in accordance with a change of the required air-fuel ratio.
