Diseño, simulación y análisis del rendimiento de corrientes de hidrógeno en un motor de combustión interna

Abstract

This work is part of the European project HYLANTIC EAPA_204/2016 "The Atlantic Network for Renewable Generation and Supply of Hydrogen to promote High Energy Efficiency", coordinated by the Department of Chemical and Biomolecular Engineering of the University of Cantabria. This study has been carried out as as continuation of the Final Degree Thesis (TFG), within the framework of the international programme known as "European Project Semester" (EPS) and which in turn has been developed within the framework of the Grant for Collaboration with University Departments issued by the Ministry of Education with the same department. The research is based on the design, simulation and data analysis for the extraction of results of an internal combustion engine adapted to be fuelled by hydrogen (H₂-ICE), modifying its design substantially concerning to injection strategy, called direct injection (DI), studying its main strengths and weaknesses, and considering the use of other alternative fuels such as methane (CH₄) and Coke Oven Gas (COG). These factors are encouraged because of the recent trend about 2 technologies. For this reason, the main objectives have been set according to the problem statement, which are: • Prove that there is an improvement in H₂ performance with the new design. • To check if the engine behaves the same for the rest of the fuels under study. • The correct selection and design of the engine, • The addition of injection in the simulation software. • Study the influence of engine speed (rpm) and Air-Fuel ratio (λ) on engine performance and emissions, as well as compare the engine performance results in the H₂, CH₄ and COG simulations, as a function of temperature, pressure and emissions.
