A control apparatus of an internal combustion engine which has an air-fuel ratio adjusting device for adjusting the air-fuel ratio of an air-fuel mixture, and an ignition device for igniting the air-fuel mixture. When a knock sensor detects a knocking state of the engine, it delivers a knock signal corresponding to the detected knocking state. In response to the knock signal delivered from the knock sensor, first correction data, which instantaneously prevents the knocking state by changing to a high degree, and second correction data, which corresponds to the properties of fuel used and prevents the knocking state by changing to a low degree, are calculated. The ignition timing is set in accordance with the calculated first and second correction data, whereby the operation of the ignition device is controlled. The air-fuel ratio is set in accordance with at least one of the first and second correction data, whereby the operation of the air-fuel ratio adjusting device is controlled. |
