ABSTRACT:
A knock control device having a knock detecting means and an ignition timing control means is provided with a temperature sensor for detecting the temperature of the exhaust system of an internal combustion engine. If the knock detecting means detects occurrence of knock when the temperature of the exhaust system is lower than a predetermined value, the ignition timing control means retards the ignition timing by a first angle which is most desirable for suppressing the knock, while if the knocking detecting means detects occurrence of knock when the temperature of the exhaust system is not lower than the predetermined value, then the ignition timing control means retards the ignition timing by a second angle which is smaller than the first angle.
