Flow Evaluation and Simulation Fuel in the Injector of a MEP Engine When Using Fuels Alternatives

Abstract This work showed the use of alternative fuels as a means of generating energy using biodiesel based on frying oil through an evaluation and simulation of the fuel flow in the injectors of a MEP engine. With the application of the experimental method, tests were carried out on normal diesel, biodiesel with mixtures B10, B20 and B100 in the mechanical injectors to observe their opening pressure, closing time, spray angle and their dripping. With the data obtained from the tests in the laboratory, the statistical method was used to verify if they were in the usual operating range of the injectors to proceed with the simulation in ANSYS software, evaluating the behavior of the fluid inside the injector, in addition to obtain values of pressures and velocities in the flow of the fluid within it. In this way, alternatives were evaluated and proposed in the use of biodiesel as an alternative fuel, choosing the geometry of 5 outlets because the pressure remained constant with the use of diesel fuel and the frying oil biofuel, with all the combinations, which which indicated that a variation was necessary and not other complementary accessories on the engine.
