ABSTRACT:
Only an air-fuel ratio of one specific cylinder is forcibly shifted by the correction of the fuel supply quantity, and the fuel supply characteristic error rate of fuel supply means of this one specific cylinder, where the air-fuel ratio is forcibly shifted is detected based on whether or not the influence of this shifting of the air-fuel ratio is manifested on the air-fuel ratio feedback correction value set, based on the average air-fuel ratio in respective cylinders, as expected. Correction values of the fuel supply quantity are set separately for respective cylinders, based on the fuel supply characteristic error rates thus determined separately for respective cylinders.
