Summary:

Emission intensity was measured at a wavelength of 395 2 nm (corresponding to the characteristic spectrum of the HCHO radical) and absorbance was measured at 306 4 nm (corresponding to that of the OH radical). The emission intensity and absorbance waveforms recorded during engine operation on n-heptane show behavior indicative of the passage and degeneracy of cool flame in the preflame reaction interval. As the combustion chamber wall temperature approached an overheated state in the transition from normal combustion to knocking operation different preflame reaction behavior was observed which is thought to correspond to the presence of a negative temperature coefficient region related to the ignition delay time
