Patent ID: 7337767

Claim:
A device for controlling an engine, comprising: combustion noise suppression means for suppressing combustion noise of a combustion chamber; and control means for controlling the combustion noise suppression means, wherein the engine is connected to manual transmission means, the device further includes control amount setting means for setting a control amount of the combustion noise suppression means 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, the target combustion noise characteristics being set so that constant-combustion-noise lines, which represent on a coordinate plane with the speed and torque of the engine being coordinate axes distribution of combustion noise values of the engine within a predetermined range on the coordinate plane, provide a smaller absolute value of a speed variation relative to a torque variation from any point on the coordinate plane than constant-output lines which represent on the coordinate plane distribution of output values of the engine within the predetermined range, and the control means controls the combustion noise suppression means according to the control amount set by the control amount setting means.
