Abstract: Fuel injection is a critical process in internal combustion engines, as it plays a key role in determining engine performance and emissions. The effectiveness of diesel engine depends greatly on the fuel injector nozzle. The size and geometry of the fuel injector affect the combustion characteristics of the diesel engine as well as the performance over the lifetime of the engine and the mechanical durability of the injector. So, in this paper a computational fluid dynamics (CFD) simulation of fuel injection with pressure analysis was performed. The aim of the simulation was to investigate the fuel injection process and its effect on the pressure distribution in the combustion chamber. CATIA software is used to design the fuel injector model. The simulation was carried out using ANSYS Fluent software, and the results were analysed to determine the fuel spray characteristics and pressure distribution during the injection process.
