<P>PROBLEM TO BE SOLVED: To provide an internal combustion engine control device optimizing both of an injection style and an intake condition. <P>SOLUTION: This device is provided with a cylinder pressure detecting pressure in the combustion chamber and a fuel pressure sensor detecting pressure of fuel fluctuating with accompanying fuel injection from an injector. Combustion rate as combustion characteristics in a cylinder is calculated (S95) based on both detection value of cylinder pressure detection value and fuel pressure detection value. EGR quantity, supercharging pressure, and injection star timing are corrected according to the calculated combustion rate (S110, S120, S130). Consequently, injection start timing (injection style), supercharging pressure, and EGR quantity (intake state) are coordinated and controlled according to combustion characteristics in the cylinder. <P>COPYRIGHT: (C)2010,JPO&INPIT |
