Description

In diesel engines, the interaction between evaporative sprays and combustion wall is unavoidable phenomena. The fields with large temperature gradient should be occurred near the wall against high temperature ambient gas as well as evaporative vapor fuel. Thus, this paper is focusing on the quantitative measurement of fuel vapor concentration in nonreacting field near the wall, where large temperature gradient is existing, by applying exciplex fluorescence method. Two – wavelength exciplex system is originally developed to detect the quantitative vapor concentration fields inside the wall impinged evaporative spray, by accessed with the signal ratio of two wavelength, based on the predetermined calibration experiments. By applying this method, quantitative fuel vapor concentration could be obtained with a variation of, fuel injection pressure and wall – nozzle distance.
