In the maritime transportation, e-fuels represent a valid alternative to fossil energy sources, in order accomplish European Union goals terms of climate neutrality. Among e-fuels, ammonia-hydrogen mixtures can play leading role, as combination two allows exploit advantages each one, simultaneously compensating their gaps. The main goal present publication is proposal robust numerical framework based on 0D, 1D and 3D tools for CFD analyses internal combustion engines fueled with mixtures. engine model provides boundary conditions multi-dimensional investigations estimates overall performance. in-cylinder detailed are proficiently used predict efficiency (via well-established G-equation supported by laminar flame speed correlations both ammonia hydrogen) emissions (with chemistry approach). Heat transfer knock tendency evaluated well, in-house developed models. As 0D/1D chemical kinetics calculations, firstly they support (for example via generation ignition delay time tables). Moreover, allow insights aspects such NOx formation, individuate mixture qualities able strongly reduce emissions. paper offers also indications designers effectiveness NH3–H2 substitutes traditional fuels marine applications. fact, proposed preliminary tested convert an existing Diesel Different proportions (among fuels) investigated, included pure hydrogen 80mol%-20mol% selected best compromise. Thanks anti-knock quality (limited) addition enhancer, supplied operate free keep same performance original one. Simultaneously (neglecting presence lubricant oil chamber) unburned hydrocarbons, carbon monoxide dioxide eliminated. Still comparison version, heat similar, formation much greater range (here working hours) noticeably reduces.
