Experimental studies of the Homogeneous Charge Compression Ignition (HCCI) combustion was carried out. The fuels used were n-butane/air mixtures and a compact rapid compression machine was used to create a high pressures and high temperatures environment. The Emeleus cool flame band which originated from the formaldehyde chemiluminescence was observed during the cool flame appearance (compression ratio = 13.5:1, equivalence ratio = 0.55:1, temperature before compression = 313 K). The blue flame came out, the emission spectrum of which was similar to that of the cool flame with overlapping by HCO bands. During the main heat release duration, the hot flame emission spectrum was observed where the distinct OH emission at 306.4 nm appeared, and it was superimposed on the CO continuum. Pulsed Flame Jet showed a potential for controlling the start of HCCI combustion directly. The chemiluminescence spectra and the color high-speed images of combustion initialed by PFJ were also obtained. In the jet of PFJ, the emission spectrum obtained was composed of the distinct OH emission at 306.4 nm and CH emission at 431.5 nm superimposed on the CO continuum. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
