Control device for internal combustion engine

The present invention provides a Control device for an internal combustion engine capable of inhibiting change of combustion noise. The combustion control part of a control device (200) for an internal combustion engine (100) configured to calculate a first vibration level of an engine body (1) at a first judgment frequency band of a second overtone of a specific frequency band based on vibrationacceleration detected by a vibration sensor (210) and, when the first vibration level is less than a predetermined first reference vibration level set in advance according to the engine operating state, to correct one or both of a target injection amount and target injection timing so that the first vibration level becomes the first reference vibration level or more. 一种内燃机的控制装置，抑制燃烧噪音的变化。内燃机(100)的控制装置(200)的燃烧控制部构成为，基于由振动传感器(210)检测出的振动加速度算出特定频带的2倍频的第1判定频带中的内燃机主体的第1振动等级，在第1振动等级小于根据内燃机运转状态预先设定的预定的第1基准振动等级时，以使得第1振动等级成为第1基准振动等级以上的方式修正目标喷射量和目标喷射正时中的一方或双方。
