摘要： An engine revolution number is controlled by operating opening and closing of a throttle valve by an engine revolution number control means on the basis of a deviation between a detected engine revolution number and a target engine revolution number, and air-fuel ratio control means applies the engine revolution number and the intake air flow rate to a predetermined numerical formula which is derived from a plurality of sets of data groups including the intake air flow rate and air-fuel ratio, which are obtained from a predetermined experiment model, and expresses the relationship between each data, to thereby calculate a fuel injection time for realizing a target air fuel ratio. A target air fuel ratio is thus realized while minimizing any delay of a response even during a transient operation, and thus, good engine operability is always acquired.
