Simulation and modelling
A significant goal of the Simulation and modelling subgroup is the transformation of multi-fuel powertrains, particularly in the marine engine sector, aiming to address emissions challenges. The subgroup explores combustion modes for alternative fuels, develops a versatile base engine, and customises aftertreatment systems for new fuels such as ammonia and hydrogen. Simulation and modelling activities at the University of Vaasa are primarily conducted within the EPS research group.
Through collaborative efforts within our organisation and partnerships with industry leaders, we strive to drive innovation and contribute to the evolution of internal combustion engine technology. Together, these endeavours underscore the university's dedication to pioneering research, sustainability, and the exploration of alternative fuels and technologies.
The University of Vaasa is currently at the forefront of diverse and innovative research projects, showcasing a commitment to pioneering initiatives. One of the key ongoing projects is a comprehensive study focused on the development and validation of engines using hydrogen-ammonia carbon-neutral fuels. This research spans various aspects of internal combustion engines (ICE), from mapping requirements to thermal output modelling of alternative fuels such as H₂ and NH₃.
