摘要：
A concept for temperature determination of fuel-air mixtures using Laser-Induced Fluorescence (LIF) is presented. For this purpose the fluorescence spectra of gasoline were measured after excitation by frequency quadrupled Nd:YAG laser light at 266 nm in a temperature range between 373 K and 448 K. Experiments were performed with colorless near-standard gasoline conforming to the Euro-super specifications. It is shown that the intensities of two fluorescence bands (290-302 nm and 332-344 nm) can be used to determine the temperature.
