Abstract
Provided is a control apparatus for an internal combustion engine, which can favorably suppress an occurrence of abnormal combustion regardless of its operational conditions. An occurrence probability of abnormal combustion of the internal combustion engine () is obtained on the basis of a fuel dilution index. An expected value I of the number of occurrences of abnormal combustion per a predetermined time period is calculated on the basis of the occurrence probability of abnormal combustion. The upper limit value of a torque generated by the internal combustion engine () is limited low so that the expected value I does not exceed a predetermined tolerable value.
