Numerical Study on Effect of Injection Rates on Combustion and Emission Performance

Article Preview

Abstract:

As a study of natural gas engine, three-dimensional numerical simulations of diesel injection rates were conducted by using AVL FIRE code. And particularly the effects of the injection rates in the pilot diesel jets on the engine combustion and emission were analyzed. It is found that injection rate in the pilot diesel jets plays an important role on the emission, and slow ending rate of the injection keeps lower NO and Soot.
