| Abstract: | In this paper,by using a CCD camera,high speed A/D card(sampling rate 1m/s),computer and some other apparatuses,an investigation on the instability of oil-gas two phase flow in fuel injection system has been carried out on a running diesel engine. With the analysis of sound velocity, pressure oscilation and frequency spectrum of the pressure wave in different cycles under the same operation condition,a study of the changing regularity of bubbles quantities and its influence on sound velocity and pressure oscillation has been made. |
