Abstract

The fuel supply system is one of the most critical components of a diesel engine. The processes of fuel injection, atomization, and mixing are crucial in determining the efficiency, power output, economic performance, and environmental impact of the diesel engine's operation. Furthermore, with the deteriorating environmental conditions in major cities, the toxicity levels of diesel exhaust emissions have become a priority concern. The mathematical model of the injected fuel jet's development and combustion enables the direct calculation of various indicators related to the engine's operating process. The value of these results lies in the fact that numerical modeling allows for the investigation of the influence of injection characteristics, fuel supply timing and duration, as well as combustion chamber design parameters on the indicator diagram and cycle efficiency across a wide range of engine speed and load conditions.
