Simulation Research on the Spray and Formation of Mixture of Gasoline Direct Injection Engine

Article Preview

Abstract:

A computational model of a GDI engine is established by 3D CFD simulation software. A simulation on the formation of mixture of the engine under 1500r/min, full load conditions are carried out. The calculation results provide a reference for the optimizing of the engine.
