The combustion process in diesel engines is under constant study. A major research effort is being made to establish a better understanding of diesel combustion. Many issues regarding diesel combustion remain unresolved, and these issues may prevent the use of diesel engines due to increasingly stricter air pollution legislation. This study dealt with the effect of the fuel injection profile on diesel engine performance through the utilisation of different multiple injection strategies. From the engineering point of view, establishing a continuous fuel injection profile with the ability to change fuel flow is impossible today. The most feasible engineering solution to continuous fuel injection profile is the utilisation of multiple injection events, which enables control of fuel flow. Multiple injection as a tool to control combustion in diesel engines has been studied for several years, this study investigated the effect of different two injections strategies on the combustion. The results and the analysis of the results demonstrate that multiple injections affect both the physical processes and the kinetics of combustion. Proper division of the injected fuel among injections may decrease engine emissions considerably while causing only a minor decrease in engine efficiency.
