Behavior of Fuel Spray injected by Tailpipe Injector for Post Treatment of Diesel Engine Emissions (Fourth Report)

- Numerical Analysis of Wall Impinging Spray in a Low Injection Pressure Spray -

Abstract

We focused on the behavior of spray in tailpipe. Wall impingement phenomenon in the tailpipe is different from phenomenon in the engine cylinder. In this study, we calculated the wall impinging spray in a low injection pressure spray with the model which considering the change in the impingement behavior due to the boiling state. By using this model, the wall impingement behavior of the spray is predicted with high accuracy.
