ABSTRACT:
An apparatus for suppressing knock in an engine by first detecting the knock and sequentially renewing a control quantity, which is fed to means for controlling the running mode of the engine, in the direction of knock suppression until the knock detection output becomes nonexistent. The apparatus is equipped with means capable of prohibiting renewal of the control quantity when the engine is in any transient running state such as a stage immediately after its start, thereby preventing unstable running of the engine.
