Control device for internal combustion engine

A control device for an internal combustion engine having a cylinder and a spark plug, said control device comprising:

• a fuel feeding means for feeding an amount of fuel into the cylinder, the fuel feeding means feeding a part of the amount of fuel into the cylinder during an intake stroke to form an air-fuel premixture, and feeding the remaining part of said amount of fuel into the cylinder during a compression stroke to form an air-fuel mixture around the spark plug for ignition;
• a pressure detecting means for detecting a pressure in the cylinder;
• a combustion state determining means for determining a combustion state in the cylinder on the basis of the pressure detected by the pressure detecting means;
• and
• a fuel feeding control means for controlling a ratio of the part of the amount of fuel to be fed into the cylinder during the intake stroke to the amount of fuel to be fed into the cylinder on the basis of the combustion state determined by the combustion state determining means so that a good state of combustion is obtained.
