| Abstract: | In this paper, it is discussed that using the practical measuredvalues of pressure wave at inlet of fuel injector as the input data of computer for the simulating calculation of the average diameter of particle size of fuel spray penetration as well as adopting the empirical formula for calculating the average diameter of particle size of fuel spray penetration under the condition of constant pressure, the average diameter of particle size of fuel spray penetration under variety of pressure can directly be calculated by means of the cutting apart method of pressure curve of fuel injection. In addition, the effect of variety of injection conditions onthe average diameter of particle size of fuel spray penetration has been discussed as well. |
