Abstract
In a knocking control device comprising an exhaust bypass valve driven by the diaphragm actuator and a knocking control circuit, the amount of bypassed exhaust gas is adjusted in accordance with the knocking, the upper and lower limits regarding the opening degree of the control valve are determined in accordance with the opening degree of the throttle valve and the signal determining the upper limit concerning the opening degree of the control valve is prior to the signal determining the opening degree of the control valve due to the knocking signal when the opening degree of the throttle valve is changed. Thus, an increase in the output of the engine and an improvement in specific fuel consumption is achieved and the durability of the engine is improved due to the elimination of knocking and a decrease in the temperature of the exhaust gas.
