<p><P>PROBLEM TO BE SOLVED: To provide a combustion control device for an internal combustion engine, equalizing an in-cylinder temperature of each cylinder, while suppressing variation in air-fuel ratio in each cylinder. <P>SOLUTION: The combustion control device is applied for the internal combustion engine 1. The internal combustion engine 1 includes the plurality of cylinders 2 arranged in a predetermined direction, a first intake port 3 leading intake air into one area in the arrangement direction where an in-cylinder combustion temperature is relatively high and a second intake port 4 leading the intake air into the other area in the arrangement direction where the in-cylinder combustion temperature is relatively low are connected to each of the cylinders 2, and a first fuel injection valve 5 is disposed to the first intake port 3 and a second fuel injection valve 6 is disposed to the second intake port 4. The combustion control device includes: a fuel injection control means controlling fuel injection amounts of fuel injection valves 5, 6 so that the fuel injection amount of the first fuel injection valve 5 is larger than that of the second fuel injection valve 6; and an air volume reducing means reducing an air volume so that the volume of air lead into the second intake port 4 is smaller than the volume of air lead into the first intake port 3. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
