<p>The present invention is to suggest an electronic air-fuel ratio control apparatus which controls an air-fuel ratio of a burner in real time by using an electronic sensor, and also realizes a high performance level of a chemical sensor. To achieve this, the present invention can obtain a measurement value from an electronic sensor measuring gas concentration inside a combustion chamber by reacting the same to a wavelength of a flame inside the combustion chamber, and a chemical sensor measuring exhaust gas concentration by chemical reaction with the exhaust gas discharged from the combustion chamber; determine a value at the same period of time among detection values of the electronic sensor and the chemical sensor by referring to detection delay time which is the difference of measurement time between the electronic sensor and the chemical sensor, generate a correction value with regard to the gas concentration with the exhaust gas concentration corresponding to the same period of time, correct the measurement value of the electronic sensor by using the correction value, and control the air-fuel ratio inside the combustion chamber in real time by using the corrected gas concentration of the electronic sensor.</p> |
