Almost all the vehicles on road today are powered by internal combustion (IC) engines. Internal combustion engine is a heat engine in which the chemical energy of the fuel released in the combustion chamber is directly used to produce mechanical work. The performance of a DI Diesel Engine depends on many parameters like the time scales of the intake airflow, Fuel injection timings, Dynamics of turbulent reacting flows, Air fuel ratios and so on. It is well known that fuel injection strategies including fuel injection timings play a vital role in the performance of a DI Diesel engine. Computational Fluid dynamics (CFD) has emerged as an inevitable tool in the design of IC engines. Unlike the conventional experimental techniques, CFD predicts the detail insight into the spatial temporal variations of all the variables, without modifying or installing the components. Advent of powerful hardware, parallel processing techniques, cloud computing further enhanced CFD to significantly reduce the cost and turnaround time in the design process. In this study Computational Fluid Dynamics is used to investigate the effect of split injection system in comparison with uniform injection on the performance and emission components of a DI Diesel Engine.
