PURPOSE:To prevent an overcontrol of knocking, by equipping an engine with a means, which sets its combustion condition, and setting a peak value, measured by a vibration sensor when the engine is placed in a condition that no knocking is generated, to a decision level. CONSTITUTION:A knocking control means 101 performs a control of preventing knocking when an output value from a vibration sensor 100 is larger than a decision level set by a decision level setting means 102. Here the decision level is a peak value measured by the vibration sensor 100 when a combustion condition, set by a combustion condition setting means 103, is the condition that no knocking is generated. In this way, the knocking control can be performed in good accuracy with no generation of knocking corresponding to unevenness and aging deterioration or the like of the vibration sensor 100. |
