摘要： PROBLEM TO BE SOLVED: To provide an air-fuel ratio control device of an internal combustion engine that can suppress the fluctuation of air-fuel ratio when injection modes are changed.SOLUTION: An engine 11 includes a port injective injector 22 and a tube interior injective injector 17. An electronic control device 30 calculates an air-fuel ratio offset value to offset a fuel injection amount so that an actual air-fuel ratio of the engine 11 reaches a target air-fuel ratio.

摘要： PROBLEM TO BE SOLVED: To shorten the time required to update a learning value of the alcohol concentration to a value in conformity with an actual alcohol concentration via learning value updating control of the alcohol concentration.
SOLUTION: An electronic control device of an engine calculates air-fuel ratio feedback correction values FAFL and FAFR of a fuel injection quantity with each bank based on a dissociation tendency of the exhaust air-fuel ratio detected by an air-fuel ratio sensor arranged with each right-left banks and the target air-fuel ratio. Learning values ALCGL and ALCGR of the alcohol concentration included in fuel, are updated with each bank based on the air-fuel ratio feedback correction values. The fuel injection quantity is calculated based on an average value ALCGAVE of the respective learning values of the alcohol concentration. When operating the engine after feeding oil, when determining the effect that the alcohol concentration included in the fuel becomes equal between the right-left banks, the respective learning values of the alcohol concentration on both eight-left banks, are changed to the average value ALCGAVE of the respective learning values just before the alcohol concentration updated with each bank.
