Dual-Fuel System ARTEMIS for Marine Propulsion Engines

For marine applications, focus is shifting to dual fuel technology, aiming for a significant reduction in fuel costs as well as compliance with stricter emission standards. The ARTEMIS Dual Fuel System offers a complete, tailor-made dual-fuel solution based on proven and certified components. For large low and medium-speed engines with an output power range between 1000 kW and 10 MW, the multi-point gas admission based ARTEMIS version is best suited to avoid fuel losses. It incorporates a dual-fuel ECU, multiple gas admission valves and an EFI controller as main components. The single port gas injection concept assures best load response, a low risk of backfiring and optimal conditions regarding fuel consumption and emissions.
