Beschreibung
Zusammenfassung:	A control device for an engine is provided, which includes a knock intensity sensor configured to detect a knock intensity, an output adjustment mechanism configured to adjust an engine output torque, and a controller configured to control the output adjustment mechanism based on the knock intensity. The controller executes a first control in which the output adjustment mechanism is controlled to reduce the knock intensity when the number of strong knocks that is the number of times the knock intensity becomes a second determination intensity or greater is a given determination number or less and when the knock intensity is greater than a first determination intensity, and executes a second control in which the output adjustment mechanism is controlled to reduce the maximum torque more than when the number of strong knocks is the determination number or less, when the number of strong knocks is greater than the determination number.
