    • 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.
    • 点火正时控制装置可以在不产生输出转矩损失的情况下获得高输出转矩,并且避免由于连续的敲击发生导致的可听性的恶化。 气缸专用点火正时设定部分包括参考点火正时控制部分和具有与发动机气缸数相同数量的校正值的气缸特定校正值设定部分。 参考点火正时控制部分计算所有气缸共用的基准点火时间,并将所有气缸的点火正时均匀地控制到延迟角侧,以防止连续敲击的发生。 气缸特定校正值设定部分计算气缸特定校正值,以补偿气缸特定的最佳点火正时的变化,并且设定除了爆震频率等于或等于预定值以上的气缸以外的气缸的专用校正值,以便 提高点火时间。
