ABSTRACT:
In a device for controlling an engine, comprising combustion noise suppressor for suppressing combustion noise of a combustion chamber and controller for controlling the combustion noise suppressor, the device further includes control amount setter for setting a control amount of the combustion noise suppressor so that target combustion noise characteristics corresponding to a required amount of acceleration or deceleration exhibit a slower change in combustion noise than combustion noise characteristics corresponding to output characteristics of the engine over before and after acceleration or deceleration, wherein the controller controls the combustion noise suppressor according to the control amount set by the control amount setter. On the event of a rapid acceleration, a rapid change in the combustion noise in the initial stage of the acceleration is prevented to improve driving comfort.
