The comparison of spark ignition systems and corona ignition systems is performed by changing a spark plug to a corona igniter in an existing engine configuration on an Engine-in-the-Loop test bed. In this investigation visual inspection of the inflammation is done comparing visible image with spectral resolved two-dimensional information investigating the for flame initiation relevant OH*, CH* and \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\rm C}_{2}^{*}$$\end{document} chemiluminescence. A general comparison between optical and thermodynamic analysis is performed. The observations are then used to evaluate transient cycle-to-cycle comparisons of the two ignition systems.
