Engine Control System – Dual Fuel
Fig. 16.00.01: ME-GI-ECS overview of the ME-ECS core and GI extension
The ME-GI engine control system, (ME-GI-ECS),
is a common control system which is able to con-
trol all the functions known from the ME-engine.
The ME-GI-ECS also controls the gas injection as
well as the additional functionality and auxiliary
systems related to the handling of gas on the en-
gine and in the machine room, by means of:
• Electronically profiled fuel oil injection
• Electronically controlled exhaust valve actuation
• Governor/speed control
• Start and reversing sequencing
• Cylinder lubrication
• Variable turbocharging (if applied)
• Electronically controlled gas injection
• Sequencing change-over between fuel oil and
dual fuel operation
• Gas combustion monitoring and safety gas
shutdown
• Double-pipe ventilation and leak monitoring
• Sealing oil control
• Purging of gas piping with inert gas
• Interface to the FGS system.

For gas safety reasons, many functions are dupli-
cated, and as a result of this, the GI extension is
divided in two main parts: The GI control system
and the GI safety system.
Fig. 16.00.01 illustrates how the ME-ECS core
controls both the pilot and gas injection. The GI
extension handles gas related safety control and
gas plant control, including interface to the FGSS
control system.
