Abstract
Acetaldehyde has been used as a fluorescent dopant for two-dimensional imaging of the flame front in an internal-combustion-engine simulator. The molecule was excited with a XeCl-laser-light sheet at 308 nm, and broadband fluorescence centered at 400 nm was detected. In this way, the flame front could be marked by mapping regions of unburned gas. Also, the intake process into the engine could be followed.Keywords
