ABSTRACT:
A fuel supply controller for an internal combustion engine includes an acceleration mode detector, an incremental fuel supply rate calculator, and a fuel supplier. The controller sets a smaller incremental fuel supply rate with increasing engine speed to prevent excessive fuel supply to the engine during acceleration. A fuel supply corrector, a correction inhibitor, and a correction inhibitor canceller are provided for improved acceleration performance regardless of the mode of acceleration. An acceleration mode discriminator and an incremental fuel rate supplier provide proper fuel control even with increasing acceleration. The controller can use first and second control maps for controlling fuel supply. A map discriminator provides for a smooth changeover between maps.
