Abstract:
A knock control apparatus for an engine includes: a first determination device that determines whether the engine is knocking based on an output signal of a knocking detector provided in the engine; a controller that retards an ignition timing of the engine when the first determination device determines that the engine is knocking; and a second determination device that confirms whether the engine is knocking based on an output torque of the engine that is obtained when the controller retards the ignition timing.
