Dual Fuel Management ARTEMIS
Conversion from diesel to dual-fuel combustion happens for two main reasons: The reduction of fuel costs and the reduction of emissions. HEINZMANN dual-fuel systems rely on proven components and offer solutions for the specific requirements of stationary gensets, compressor applications, vehicles and engines. Through precise control of diesel and gas metering they ensure optimal performance in both diesel and dual-fuel mode. The features and benefits of ARTEMIS systems include:
- High conversion ratios
- Improved engine response
- Fixed or variable diesel in gas mode
- Separate governor settings for diesel, gas and transfer mode
- Automatic mode selection, automatic switch to diesel if gas supply fails
- Suitable for different gas qualities: Natural gas, sewage gas, landfill gas
- Low investment costs

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.

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 small and medium-sized high-speed engines with an output power range between 500 kW and 2000 kW, the gas mixer based ARTEMIS version is best suited in terms of costs and conversion ratio. A high-precision gas metering unit operates at its core, which accurately controls the gas flow under all ambient conditions and ensures an optimal diesel substitution rate at any load.
