Abstract:
A control apparatus for controlling an amount of fuel injected into an internal combustion engine, comprising a controller:that corrects an amount of air introduced into the internal combustion engine at a startup time of the internal combustion engine based on a required amount of air that is an amount of air needed to maintain a predetermined value of rotation speed of the internal combustion engine during an idling operation after a warm-up of the internal combustion engine; and that computes the amount of fuel injected into the internal combustion engine at the startup time of the internal combustion engine based on a predetermined startup-time engine operation state that is other than an amount of air introduced into the internal combustion engine; and that corrects the amount of fuel injected into the internal combustion engine at the startup time based on a ratio between a present required amount of air and a required amount of air under a new-vehicle condition.
