FRISCO-LIPSA - focused research on injection, sprays and combustion effects of large engine injector-internal phenomena with sustainable fuels for shipping such as ammonia

Abstract

Decarbonizing international shipping requires shifting from fossil fuels to sustainable options such as ammonia. These fuels differ greatly in properties, demanding a fundamentally new design of fuel supply to the combustion chamber. The project studies technical and physical phenomena between fuel and the injection system. Key processes (i.e. jet propagation, mixing, igni-tion, combustion, and emission formation) depend on these interactions, influencing engine performance and pollutant output. Experimental work on systems representative of large marine engines improves understanding and simulation tools, enabling the development of robust injection technologies and supporting optimization of engines for reliable operation with sustainable fuels.
