Dual-Fuel Systems 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.

System Overview

Software

MVC 01-24

A solenoid valve control system for industrial diesel, gas and dual-fuel engines with a maximum of 24 cylinders. Enables up to seven precise injections per cylinder and stroke; large number of I/Os enables optimum engine operation and monitoring; can be used with any control system based on solenoid valves; combined with MEGASOL injection valves for gas injection systems. What’s more, up to 3 actuators can be actuated directly, for instance to control the air volume (throttle valve, turbocharger bypass, wastegates). It can be expanded as a redundant system for use in ship engines.

MEGASOL Marine

Gas Admission Valve MEGASOL Marine

MEGASOL valves are designed to operate with a comparatively high differential pressure of supplying air and gas. They are characterised by excellent load response, precise dosage and individual adjustment of gas quantity for each cylinder. MEGASOL valves have a very low leakage when closed and are easy maintain. HEINZMANN provides a marine version of the MEGASOL 200 II - 425 II, developed specifically for marine applications.

Technical data

Power range: 60 ... 300 kW/cylinder respectively 250 .. 600 kW/cylinder
Flow rate (Z-value): 55 / 69 / 105 / 128
Max. pressure gas supply: 8 bar
Max. pressure air supply: 6 bar
Max. differential pressure: 3 bar
Voltage supply: 48 ... 110 VDC
