Abstract:
1. A knocking control apparatus for a variable cylinder internal combustion engine which can be switched between a full cylinder operation mode in which all of a plurality of cylinders are operated, and a partial cylinder operation mode in which part of the plurality of cylinders is paused by a cylinder pausing mechanism, said apparatus comprising: knocking detecting means for detecting knocking of said variable cylinder internal combustion engine; knocking control means for performing a knocking control to correct an ignition timing toward a retarding side when said knocking detecting means detects knocking; fault determining means for determining whether or not said cylinder pausing mechanism fails; and knocking control suspending means for suspending said knocking control by said knocking control means when said fault determining means determines that said cylinder pausing mechanism fails.
