PURPOSE:To prevent the occurrence of knocking and torque loss in an effective manner by storing the specified load partitioning off a learning area, while renewing the specified load with a load detected value when a knocking zone is expanded and contracted. CONSTITUTION:A means 6 judges a high load area, and at the time of this judgment, a device 7 operated ignition timing by compensating the fundamental ignition timing on the basis of a feedback value. In addition, a means 9 judges the high load area immediately after its transition, and at the time of this judgment, the feedback value stored in a means 8 is set by a device 10 as an initial value. In these means, the specified load is stored by a means 11. Such a condition that the feedback value gives a compensation value at the timing delay side, whereas it will not exceed the specified load, for example, is judged by a means 12, and when these conditions are judged, the specified load stored on the basis of load at that time is renewed by a means 13. |
