| Abstract: | y using a detecting system with a high spectral time-resolution , the spectra of the com-bustion products including those of CH,C2, OH, CH2O and O2 in the early stage of ignitionin a gasoline engine are studied.The beginning and evolution of the ignition process as wellas the progress of the early flame can be shown clearly by the spectral response,With thespectrum method , one can obtain more accurate information about the ignition delay, the rel-ative amounts of some intermediate products during ignition , the properties of the steadycombustion and flame diffusion, the starting and combustion rate in the early stage and theformation of poisonous exhaust gases during the ignition in the gasoline engine. |
