PURPOSE:To prevent the degradation of fuel consumption by obtaining a load value from ignition timing determined for a knocking control based on relative data with load used for both an ignition timing control and a fuel feed quantity control whereby obtaining the quantity of fuel feed restraining the temperature of exhaust gas. CONSTITUTION:A knocking control device for an internal combustion engine M1 in which both ignition timing and the quantity of fuel feed are determined based on engine load, includes a knocking control means M2 which adjusts ignition timing for restraining knocking, and also includes an exhaust gas temperature control means M3 which adjusts the quantity of fuel feed to restrain the temperature of exhaust gas accompanied with the adjustment of ignition timing. In this case, the exhaust gas temperature control means M3 is provided with a computing means M4 computing the quantity of fuel feed based on the relative data between load and the quantity of fuel feed by use of the load value obtained from the ignition timing adjusted when knocking is restrained by the knocking control means M2 based on the relative data between load and ignition timing. |
