| Abstract: | Evidence is presented in the literature that common fluorescence tracer/fuel mixtures used in engine experiments, 3-pentanone/isooctane
and biacetyl/isooctane, may decompose during extended use and storage. Investigations presented here show that preferential
evaporation of the tracer and not chemical decomposition is responsible for observed decreases in fluorescence signal strength
in these experiments. |
