“…In measurement situations with significant laser attenuation, the local laser fluence changes, and, for relating measured signals to f V , information about laser attenuation is necessary or highly desirable for reconstructing the local laser fluence and thus correcting the detected pulsed-LII signal. Approaches that use the local pulsed-LII signal as a measure of the local laser attenuation for corrections in a post-processing step provide an experimentally simple method, that is, however, based on many assumptions [155,373]. Measurements of the total attenuation of the beam after passing through the interaction volume cannot fully correct for local variations of the laser fluence and their nonlinear influence on the LII signal.…”

“…In addition to the variation of injection pressures, ambient density, and pressure [223,441,442], the effect of nozzle geometry [373], including cluster nozzles [443], has been investigated with pulsed LII in high-pressure combustion vessels, and quantitative data have been used for the validation of soot-formation simulations [444]. Because, in highpressure cells, Diesel combustion can be decoupled from flow-field effects, the influence of fuel composition on soot formation has been investigated with pulsed LII [445].…”

“…Indeed, stability issues with 5-nonanone have been reported in previous work [14]. However, if the presence of oxygen was to increase the rate of tracer decomposition, the effect of the presence of oxygen on fluorescence intensity would be more important in the leading edge of the jet where the temperature and mixture history is favourable.…”

“…Applying these criteria, two molecules were identified: 5-nonanone with a boiling temperature of 188°C, and 2-decanone with a boiling temperature of 210°C. Previous tests with 5-nonanone [14] show that a good signal to noise ratio can be obtained in the presence of oxygen. However, tracer decomposition in the fuel supply system might lead to experimental difficulties.…”

“…This is in general a major limitation of many LIF tracers commonly used for in-cylinder visualisation studies. The selected tracer used in this study was 5-nonanone [14] since previous experiments in a high pressure, high temperature pre-combustion chamber have shown this tracer to be particularly suitable for imaging of combusting Diesel jets [15]. A small quantity (1% by mass) of 5-nonanone was added as a dopant to the single component (non-fluorescent) fuel dodecane.…”
