Abstract:

Laser Induced Fluorescence LIF is used for planar imaging in a Sl engine. The gasoline was seeded with three different dopants biacetyl, benzaldehyd, and tetramethyl-p-phenylene diamine TMPD. Specific problems related to the application of LIF measurements in automative engines are discussed. The non-toxic biacetyl has important advantages. In contrast to TMPD and benzaldehyd it has good vaporization properties and its fluorescence is nearly insensitive to oxygen quenching. Therefore it can also be used in fire SI engines. The linearity investigations indicate the quantitative concentration measurements can be obtained. Author
