Recently, attention has been paid to flame diagnostics and measuring techniques of combustion related flame spectra method such as mixing ratio, concentration of molecules and radicals, reaction ratio, etc. It is known that combustion radicals are vigorous where the overall combustion reaction is active. The equivalence ratio is estimated by the ratio of light emission intensities of two different wavelength, 431 nm(CH radical) and 517 nm(C₂ radical), because the ratio of CH* to C₂* luminescence varies with equivalence ratio. In present work, the emission spectra intensities of CH*, C₂* radicals of methane/air mixture ignited by CDI system, was measured simultaneously with combustion pressure and ion current which show flame development and flame speed in constant-volume combustion chamber. One of the purposes of this study is to determine flame speed by ion current during flame development. We examined flame propagation under various equivalence ratio, initial pressure and mixture temperature. The other purpose is to clarify relationship between radical intensity and flame development. Moreover, instantaneous equivalence ratio was estimated by using the ratio of CH* to C₂* radicals within 10% errors.
