This paper presents the modeling of fuel injection into the combustion chamber in compression ignition engine with different fuel types. During creation of these models, software AVL Fire from Computational Fluid Dynamics was used. Process of injection and its parameters were analyzed. Two-dimensional and three-dimensional data on the fuel injection are the conducted simulation results. The study object was the single-cylinder, high-pressure Farymann 18W engine with Common Rail direct injection. Design parameters of the power unit were the input data.
