ABSTRACT:
An air-fuel ratio detecting combustion sensor. Combustion light signals of two given waveform bands are photoelectrically converted into corresponding electrical waveform signals. On the basis of phase difference in time points at which the two signals are generated, respectively, the air-fuel ratio is arithmetically determined.
