The results show that (1) the flow inside the orifice usually exhibits two characteristic patterns, which have big differences in the pressure characteristics; (2) in the IFCDG, the difference of the pressure characteristics caused by the variation of the nozzle L/D ratio has a dominant influence on the separation of the dissolved gas from the fuel inside the orifice and is verified to account for a dramatic change in the spray pattern. %8 1994-06-01
