Gas admission valve based

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.

ARTEMIS Dual-Fuel Components

Component	Description
ECU	highly efficient ECU featuring control logics for diesel and gas sophisticated safety and engine monitoring strategies gas train monitoring unlimited diesel operation of any time
Gas mixer	gas mixers delivering very homogenous gas/air mixture over the speed and load range, pressure drop maintained to a minimum thanks to the Venturi insert
Throttle valve and Positioner	throttle valve with integrated positioner for soft switching to dual-fuel mode and for precise control of gas flow
Sensors	for pressure and temperature monitoring (gas, air, cooling water, exhaust)
Software DcDesk	Window’s based software for configuration, parameterization and programming of HEINZMANN controllers, providing manifold graphics, printouts and data records Parameters of the control device may be adjusted during operation and the response can be monitored directly.
