In an internal combustion engine (1), air is taken into a cylinder (5) from an intake passage (30) through an intake valve (15). The amount of air taken into the cylinder (5) is controlled to a target intake air amount by having an engine controller (31) operate an intake throttle (23) in accordance with an accelerator opening (APO), taking into account a predetermined response delay (T2). The engine controller (31) calculates a predicted value (Qc1) of the intake air amount on the basis of the accelerator opening (APO), and controls a fuel injector (21) to inject fuel in a target fuel injection amount (Ti) which corresponds to this predicted value (Qc1) at a predetermined timing. In so doing, an improvement is achieved in the degree of precision with which air-fuel ratio control is performed when the internal combustion engine (1) accelerates or decelerates.
A fuel injection control device for an internal combustion engine, the engine comprising a cylinder, an intake passage through which air is taken into the cylinder, an intake air amount regulating mechanism which regulates an intake air amount of the cylinder in accordance with an accelerator opening, a predetermined response delay existing between the accelerator opening and the intake air amount adjustment performed by the intake air amount regulating mechanism, and a fuel injector which supplies the intake air with an amount of fuel corresponding to the intake air amount, the fuel injection control device comprising:
