Abstract
A control device for an internal combustion engine having a cylinder and a spark plug, the control device including a fuel feeding means 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 torque fluctuation detecting means for detecting an amount of torque fluctuation of the internal combustion engine; and a fuel feeding control means for controlling a ratio of the part of the amount of fuel to be injected to the amount of fuel to be injected so that the amount of torque fluctuation detected by the torque fluctuation detecting means is less than a predetermined amount.
