The article presents a study of computer modeling of thermophysical processes occurring during atomization and turbulent combustion of biofuel (biodiesel) droplets in the combustion chamber of a direct injection engine. For this purpose, a complex computer model was developed, including mathematical, spatial, and numerical submodels for calculating a complex turbulent reacting flow. Using the developed model, computational experiments were performed to investigate the thermal and aerodynamic properties of the reacting fuel-air mixture of biodiesel, focusing on the effects of temperature and pressure variations in the combustion chamber. The research results made it possible to obtain a visualization of the reacting flow with temperature and concentration characteristics of harmful emissions during biodiesel combustion. The numerical data obtained during the modeling were compared with the results for traditional diesel fuel.
