ABSTRACT:
A control system for an internal combustion engine calculates a provisional target value of the throttle opening in accordance with an accelerator pedal travel, upon detection of a sudden operation of the accelerator pedal. The system also calculates a target pressure change in the surge tank according to the provisional target value, on the basis of the actual surge tank pressure and the cylinder intake mass airflow, using a virtual intake system model. The control system sets a target throttle opening in accordance with the surge tank pressure and the cylinder intake mass airflow, so as to provide the target pressure change under a condition of the actual surge tank volume.
