Claims

[Scope of utility model registration request]

A fuel supply control means that controls the amount of fuel supplied so that a predetermined air-fuel ratio is obtained according to the operating state of the engine, and a fuel supply that detects the amount of fuel injected into the intake pipe using Fraunhofer single diffraction light. In an internal combustion engine p air-fuel ratio control device, the internal combustion engine p air-fuel ratio control device includes a fuel supply amount detection means and a fuel supply amount correction means for feedback-controlling the set fuel supply amount based on the second detected fuel supply amount. An internal combustion engine characterized by being provided with timing detection means for detecting timing, and operation control means for operating the fuel supply amount detection means a plurality of times according to injection timing or opening/closing timing based on a signal from this detection means. air-fuel ratio control device.
