A numerical investigation on a diesel engine characteristic fuelled using 3D CFD approach

Abstract

The exhaust and performance characteristics of engine combustion are one of most highly researched area due to climate concerns. These phenomena are direct consequence of combination of air–fuel and quality of combustion. The air–fuel. The ratio of fuel to air in the combustion process plays an important role in the quality of the burn. In this study, the effects of varying the fuel spray angle (FSA), using a variety of fuels, and operating at full load are analysed. According to the findings, a variation of 120 degrees in the FSA can have a substantial advantage in terms temperature reduction for full operating range, without influencing other parameters or fuel consumption. Present numerical investigation influence and importance of FSA on engine emission, even minuscule change FSA either during production of service could have significant impact on engine emission. These variations could take place for a variety of reasons, including but not limited to: production, service, or both.
