    • There is provided an ignition timing control device for an internal combustion engine capable of appropriately performing knock learning by performing knock learning adapted to an engine combustion phenomenon. The inventor has found the principle of a knock reduction effect due to ignition retard is that “if a combustion period moves toward the retard side, a cylinder volume during the combustion period increases, resulting in curbing of rise in the temperature and pressure of unburned gas”. An ignition timing control device according to the present invention is capable of new knock learning based on the principle, which learns a “cylinder volume rate”. The cylinder volume rate is a parameter determined from the amount of change in cylinder volume. Even when an operational status changes, learned ignition timing obtained from knock control means can be set to an appropriate value by reflecting the learned cylinder volume rate.
    • 提供一种用于内燃机的点火正时控制装置,其能够通过执行适于发动机燃烧现象的敲击学习来适当地执行敲击学习。 发明人已经发现,由于点燃延迟引起的爆震降低效应的原理是“如果燃烧周期朝向延迟侧移动,则在燃烧期间的气缸体积增加,从而抑制未燃烧气体的温度和压力的升高 “。 根据本发明的点火正时控制装置能够基于学习“气缸容积率”的原理进行新的敲击学习。 气缸容积率是从气缸容积的变化量确定的参数。 即使在操作状态发生变化的情况下,也可以通过反映所知悉的气缸体积速度,将从爆震控制单元得到的点火正时信息设定为适当的值。
