ABSTRACT:
The invention provides such a knock control apparatus or method for an internal combustion engine as is capable of suitably avoiding an erroneous determination on the occurrence of knocking and controlling knocking. This control apparatus comprises a knock determiner, a controller, and a setter. If an intensity of engine oscillation detected during a predetermined knock determination period is equal to or higher than a predetermined knock determination level, the knock determiner determines that knocking has occurred. The controller controls an ignition timing on the basis of a result of the determination. The setter sets an end timing of the knock determination period at an advanced timing on the basis of the ignition timing retardation amount in the retardation control.
