Abstract

To understand the ignition and reaction processes of (oxygenic) fuels without aromatic compounds, often optical experiments are conducted. A common method, is the imaging of OH radical chemiluminescence around a wavelength of 308 nm. The separation of signals of specific species can be difficult due to various overlapping signal sources. In this study, we focus on the influence of aromatic compounds on the OH* signal at engine relevant ambient conditions. Flame spectroscopy is executed simultaneously with OH* chemiluminescence imaging for various fuels. A clear influence of soot and soot precursors on the flame signal spectrum around 308 nm is shown.
