Abstract


Mass flow rate and discharge or flow coefficient of fuel delivered by the injector of the Isuzu 4JJ1 engine are important factors to determine the thermal and the environmental performance of the thermal machine. Computational tools have been applied to model the injector subject of study, taking into account its geometrical features and performance associated with the efficiency of the mixture generated in the combustion chamber. A Computational Fluids Dynamics (CFD) study has been applied, taking into account the efficiency of the energy transfer system. The results obtained in this CFD study have defined a theoretical model of the injector discharge coefficient for different injection pressure levels identified. On the other hand, a sensitivity analysis of the numerical model has determined an optimal setting of the model, which ensures the optimal intake of the computational resources needed to solve the system of partial differential equations that defines the behavior of the injection flow in a virtual environment. This methodology has defined the real behavior of the mass flow rate and discharge coefficient of the flow by means of computational tools in a virtual environment. The robustness of the model has been verified by comparing experimental measurements and numerical data treated with IcoFOAM solver. An error of less than 9 percent between simulated data and experimental measurements has been reached. This approach may be applied to reduce the need to perform experimental tests to define coefficients necessary to study the thermodynamic modeling and the flow behavior of fuel in the combustion chamber of diesel engines.
