The timing of spark ignition is set in normal operating conditions at a programed spark advance angle corresponding to the MBT (minimum spark advance for best torque). When knocking of the engine is detected by a vibration sensor, the ignition timing is delayed by a predetermined amount, e.g., 2DqDq

A method for controlling a timing of spark ignition for an internal combustion engine having an output shaft rotated by a piston, the method comprising the steps of: monitoring a magnitude of vibration of said internal combusion engine by vibration responsive means coupled to said internal combustion engine; comparing said magnitude of vibration monitored by said monitoring step with a reference magnitude to generate a first signal when said magnitude of vibration is larger than said reference magnitude and to generate a second signal when said magnitude of vibration is smaller than said reference magnitude; incrementing altering an instantaneous timing of spark ignition by incrementally retarding said instantaneous timing by a first predetermined value in response to said first signal and by incrementally advancing said instantaneous timing by a second predetermined value in response to said second signal, said first predetermined value being larger than said second predetermined value; and supplying said internal combustion engine with a spark ignition at a timing of spark ignition corrected by said altering step to control the ignition angle just below the condition where knocking of said engine occurs.
