ABSTRACT:
A control device for an internal combustion engine having a cylinder and a spark plug, the control device including a fuel feeding unit for feeding fuel into the cylinder, feeding a part of an amount of fuel to be injected during an intake stroke to form an air-fuel premixture, and feeding the remaining part of the amount of fuel to be injected during a compression stroke to form an air-fuel mixture around the spark plug for ignition; a pressure detecting unit for detecting pressure in the cylinder; a combustion state determining unit for determining a combustion state in the cylinder on the basis of the pressure detected by the pressure detecting unit; and a fuel feeding control unit for controlling a ratio of the part of the amount of fuel to be injected to the amount of fuel to be injected on the basis of the result of determination of the combustion state determining unit so that a good state of combustion is obtained.
