Cfd Modeling of the In Cylinder Flow In Direct-Injection Diesel Engines

Abstract

Internal combustion engines today is the best available source of reliable power for all industrial applications, local transport a large scale. It is called a key issue in the efficiency of these engines. All attempts to improve these engines tend to achieve maximum efficiency. Is improving the performance of diesel engines by appropriate design of the multi-slot, exhaust manifold, combustion chamber, piston, etc., the study on the impact of the configurations of the cylinder piston on the development of infrastructure. Here it is used for direct injection diesel cylinder and a study. For entry into multiple spiral density used a combination helicalspiral. An increase in the intensity of the vortex results in better mixing of fuel and air. Swirling speeds in the load can be significantly increased by proper design pressure piston. In this paper, it is a study on the impact of different air traffic piston configuration and turbulence within the cylinder direct injection (di) diesel out using the code computational fluid dynamics (cfd) fluent 13 . The three-dimensional models of pistons and cylinders openings are created in catia v5 and using 10.0 preprocessorhypermesh mix.
