ABSTRACT:
A fuel injection amount learning and controlling method capable of learning the amount of fuel injection independent of whether accessories are operated or not and without being affected by environmental conditions such as coolant temperature. The fuel injection amount learning and controlling method obtains, using an idle injection amount standard value as the standard, a fuel injection amount learning value so that the speed of an internal combustion engine (1) is a target idle speed. The method has a learning correction function that obtains in advance a relationship between load by accessories (3, 4) driven by the engine (1) and a fuel injection incremental amount that is due to the load imposed by the accessories (3, 4) and is relative to a no-load condition as the standard. To obtain the fuel amount learning value, the learning correction function measures the load by the accessories (3,4), derives a fuel injection incremental amount relative to the measured load, and corrects the idle injection amount standard value by using he incremental amount.
