The ME-GI specific engine parts
The modified parts of the ME-GI engine comprise
gas supply piping, gas block with accumulator
and control valves on the (slightly modified) cylin-
der cover with gas injection valves.
A sealing oil system, delivering sealing oil to the
window/shutdown and gas injection valves, sepa-
rates the control oil and the gas.
Apart from these systems on the engine, the en-
gine auxiliaries will comprise some new units, the
most important ones being:
• If the supply of gas is natural gas (NG) or com-
pressed natural gas (CNG) it require a high-
pressure gas compressor, including a cooler, to
raise the pressure to 300 bar, which is the maxi-
mum required pressure at the engine inlet
• If the supply of gas is liquid natural gas (LNG)
it requires a Cryogenic HP Pump and vaporiser
solution
• The ME-GI Engine Control System (ME-GI-ECS)
• Leakage detection and ventilation system, which
ventilates the outer pipe of the double-wall pip-
ing completely, and incorporates leakage detec-
tion
• Flow switches
• Inert gas system, which enables purging of the
fuel gas supply system and the gas system on
the engine with inert gas
• Gas Valve Train (GVT)
• Gas blow-off silencers
• Heat traced and insulated gas supply pipes.
