Abstract
A control device for an internal combustion engine is provided, which can carry out favorable injection amount feedback control even when a fuel property changes. A cylinder internal pressure sensor () that detects a cylinder internal pressure is included. A cylinder internal fresh air amount is calculated based on the cylinder internal pressure detected by the cylinder internal pressure sensor () (). Based on the cylinder internal pressure detected by the cylinder internal pressure sensor (), an actual heating value is calculated (). From the calculated cylinder internal fresh air amount, a target heating value in a predetermined excess air ratio is calculated (). A comparison value of the actual heating value and the target heating value is fed back to a fuel injection amount so that the calculated actual heating value corresponds to the target heating value ().
