ABSTRACT:
A knock suppression apparatus for an internal combustion engine includes a peak value sensor that senses a peak value of a knock signal indicating knocking of an engine. An analog-digital converter repeatedly converts the peak value into a digital value at prescribed intervals. The most recent digital peak value from the analog-digital converter is stored in a memory and used by a lag angle calculator to calculate a lag angle for suppressing knocking. The ignition timing of the engine is controlled according to a basic ignition timing and the lag angle. Because the analog-digital converter is constantly performing conversion, the ignition timing can be immediately adjusted to compensate for knocking.
