Relative LIF (Laser-Induced Fluorescence) intensities and their temperature/pressure dependencies of ketones, aldehydes and toluene were investigated at the excitation wavelength of 248 and 266nm. LIF intensities of aldehydes were quite weak. Although the LIF intensity of toluene is very strong, it was affected by temperature and pressure severely. In contrast, both temperature and pressure dependencies of LIF intensity of acetone and diethyl ketone were quite small, especially at 266nm excitation. Taking account of boiling point (B.P.), the suitable fluorescent additive (fuel tracer) mixed with iso-octane (B.P.=99°C) and its excitation wavelength for quantitative measurement of fuel distribution in an engine are diethyl ketone (B.P.=102°C) and 266nm, respectively.
