    • PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine inhibiting wrong decision in abnormal decision of a variable valve train of the internal combustion engine including an oil pressure change over mechanism capable of changing over pressure of operating oil between a high level and a low level.
      SOLUTION: The internal combustion engine 100 includes VVT 30, 40 which are driven by oil pressure of engine oil supplied by an oil pump 51 and can change valve timing of an intake valve 11 and an exhaust valve 21, and an oil pressure change over mechanism 60 which can change over the oil pressure between the high level and the low level. An electronic control device 70 forcibly changes over oil pressure from the low level to the high level when abnormal operation of the VVT 30, 40 with the oil pressure at the low level is detected, and determines that the VVT 30, 40 are normal when the abnormal operation is removed by changing over the oil pressure to the high level.

    • PROBLEM TO BE SOLVED: To suitably correct the steady difference between the actual air fuel ratio and a target air fuel ratio in the respective injection regions even in the case where two or more fuel injection valves have two or more injection regions different in proportion of quantity of fuel supplied to a combustion chamber from the fuel injection regions. SOLUTION: When it is determined to be in "port + cylinder injection area" (step 430), it is determined whether or not learning of "port injection region" is completed (step 440). When it is determined that the learning of "port injection region" has been completed, an air fuel ratio learnt value in the cylinder injection region is calculated on the basis of detection result of steady difference between the target air fuel ratio in the "port + cylinder injection region" and the actual air fuel ratio and the air fuel ratio learnt value in the "port injection region" (step 450).
