Pressure Injection Influence on the Combustion Process

Article Preview

Abstract:

Computational simulation for the combustion process in a DI diesel engine was performed through a code made by the author [1]. Two conditions of different injection pressure were examined in the simulation. The injection pressures are 150 MPa and 500 MPa. The combustion phenomenon was modeled as a combined process of formation of a combustible mixture and a chemical reaction. The rate of mixture formation was assumed to be dependent on the turbulence characteristics and the concentration of species in each computational cell. The rate of chemical reaction is described as an Arrhenius equation. The result agrees with the experimental result qualitatively, and the effect of injection pressure on the combustion process is well predicted.
