Re-entrant bowls for high compression ratio heavy-duty turbocharged DI Diesel have been studied by the utilization of a two-dimensional axisymmetric model of the air motion and spray formation inside the cylinder. The trend of the air motion and spray pattern obtained by changing combustion chamber parameters are compared with the trend of the engine performance like smoke, fuel consumption, gaseous emissions and heat release rate. The results of this study strongly support the hypothesis that with reentrant-shaped combustion chambers an optimum level of the air fuel mixing is achieved at low values of the inlet port generated swirl.
