In this field, computational tools like CFD and engine cycle simulation play a fundamental role. Therefore, the goal of the present work is to simulate a high speed DI diesel engine and study the combustion and major diesel engine emissions with more details, by using the AVL-FIRE commercial CFD code. The predicted values of the in cylinder pressure,  heat release rate, emissions, spray penetration and in-cylinder isothermal contour plots by this code are compared with the corresponding experimental data in the literature and is derived good agreement. This agreement makes the model a reliable tool that can use for exploring new engine concepts. %U https://ijcce.ac.ir/article_5957_311cf03d8764559736b96002e553f788.pdf
