The purpose of the research was to examine the changes in the local values of turbulent kinetic energy and temperature, as well as their impact on the local formation of nitrogen oxides and soot in diesel engine combustion chamber in the case of the base (two-fold (split) fuel injection) and alternative (different variants of five-fold fuel injection) fuel injection characteristics. We defined the optimum parameters of the fuel injection, resulting in a partially homogeneous combustion in part load mode. We found that it is appropriate to combine an alternative process of partially homogeneous combustion optimized in part load modes, with the conventional diesel combustion in normal engine duty.
