Visualization of the Qualitative Fuel Distribution and Mixture Formation Inside a Transparent GDI Engine with 2D Mie and LIEF Techniques and Comparison to Quantitative Measurements of the Air/Fuel Ratio with 1D Raman Spectroscopy 2000-01-1793

Mie-Scattering and laser induced exciplex fluorescence (LIEF) were used to visualize the distribution of liquid fuel and fuel vapor inside an optical accessible one-cylinder research engine with gasoline direct injection (GDI). Using a tracer which was developed especially for the environments of gasoline combustion engines, LIEF enables an extensive separation between liquid and vapor phase and delivers a signal proportional to the equivalence ratio. Simultaneous images of LIEF and Mie scattering proof the high quality of the phase separation using this tracer concept. The mixture formation process will be shown exemplary at one operation point with homogeneous load and another with stratified load. First results of determining the air/fuel ratio by means of linear Raman spectroscopy will be presented and compared with the two-dimensional qualitative distribution of the fuel vapor (LIEF).
