Abstract
In a method for controlling a fuel injection amount of an internal combustion engine of the present invention, an incremental fuel amount is calculated in accordance with an engine running condition when a high load state of the engine is detected, and an upper limit value of the incremental fuel amount is gradually increased at predetermined intervals. When the incremental fuel amount is equal to or lower than the upper limit value, the fuel injection amount is increased to the extent of the incremental fuel amount. When the incremental fuel amount exceeds the upper limit value, the fuel injection amount is increased with the upper limit value. With this controlling method, the fuel consumption efficiency and acceleration response can be improved and the generation of knock in the engine can be suppressed during the period of the increase of the fuel injection amount in the high load state.
