An Experiment Investigation on Process of Two-Phase Flow in Fuel Injection System of Agricultural Diesel Engine

In this paper, by using CCD camera, A/D card, computer, graphic collecting card, and the other instrument, an experiment investigation of process of two phase flow in fuel injection system of agricultural diesel was made. In conditions of empty load, part load, rated power and maximum twisting moment, the phenomenon of bubbles in fuel injection system of agricultural diesel was discovered. Complex movements of bubbles and their effect on engine performances were revealed too.
