摘要： An ignition timing control apparatus can obtain high output torque without generating output torque loss, and avoid the deterioration of audibility due to successive knock occurrences. A cylinder specific ignition timing setting section includes a reference ignition timing control section, and a cylinder specific correction value setting section having correction values of the same number as that of engine cylinders. The reference ignition timing control section calculates reference ignition timing common to all the cylinders and uniformly controls the ignition timings of all the cylinders to a retard angle side to prevent the occurrence of successive knocks. The cylinder specific correction value setting section calculates cylinder specific correction values to compensate for variation in the cylinder specific optimal ignition timings, and sets the cylinder specific correction values for cylinders other than those whose knock frequency becomes equal to a predetermined value or more so as to advance their ignition timings.
