ABSTRACT:
A controller approximates an output characteristic of an air flow meter using at least one parameter, and approximates a characteristic of a fuel injection characteristic of an injector using at least one parameter. These parameters are determined and updated based on an exhaust air-fuel ratio acquired by an air-fuel ratio sensor disposed in an exhaust passage, so that the exhaust air-fuel ratio approaches a target air-fuel ratio.
