Fuel supply control system for internal combustion engines at acceleration

摘要

A fuel supply control system for an internal combustion engine in which an accelerating fuel increment of fuel supplied to the engine is set in response to the detected change rate in the opening degree of the throttle valve. Further, the accelerating fuel increment is set in such a manner that it is smaller as the detected reduction gear ratio of the transmission is larger. Advantageously, the accelerating fuel increment is set to increase at a smaller rate as the above detected change increases within a region within which the change rate is smaller than a region in which the change rate is larger.
