Wall Shape on the Influence of the Spray Wall-Impingement under Common Rail System

Article Preview

Abstract:

In this article, the spray wall-impingement experiments were carried out under the common rail condition by image acquisition system to study the wall shape impact on the diesel spray impingement. The results showed that the scatter direction of impinged spray, shape of impinged spray can be changed by the wall shape significantly. With the increasing of injection pressure, spray splash volume relatively increases and atomization is enhanced when the spray impinges on a flat wall; the development of distance along the wall is nose-shape 90 degree > 135 degree.
