Research on Predicting Fuel Spray Characteristics of Diesel Engine

摘要：

Based on the particular structure of the co combustion chamber, the three-dimensional dynamic CFD model of the diesel engine fuel injection characteristics was established, the changing mechanism on the fuel mixture flow field and pressure field in the combustion chamber were predicted by the commercial Fluent software. The results showed that after the fuel began to spray, the oilbeam-driven vortex flow was essential to maintain. Late in the combustion, fuel droplet particles sprayed into the wall, and fuel components concentrated near the wall in the combustion chamber. The reverse squish was formatted in the initial expansion stroke.
