TY - CONF TI - Alternative Fuel For Marine Applications: Ethanol-powered Dual-fuel Technology For Emd-710 Engine AU - El-Hannouny, E AB - This presentation investigates the feasibility of ethanol-powered dual-fuel combustion for marine applications using a large two-stroke EMD-710 compression ignition engine. A dual-fuel strategy combining direct-injected diesel pilot fuel with port-injected hydrous ethanol was experimentally demonstrated under representative marine duty cycles. Results show that ethanol substitution levels of 40–50% (energy basis) can significantly reduce NOₓ and soot emissions while maintaining stable combustion, with only modest increases in CO and total hydrocarbons. The approach requires minimal engine modifications and offers a near-term retrofit pathway for reducing emissions from marine diesel engines. Ongoing and future work focuses on engine optimization and modeling to further improve fuel efficiency and emissions performance, supporting the potential deployment of alcohol-based dual-fuel technologies in marine and inland waterway vessels.
