Engine Control System ME-B

The Engine Control System for the ME-B engine is
prepared for conventional remote control, having
an interface to the Bridge Control system and the
Engine Side Console (ESC).
The layout of the Engine Control System is shown
in Fig. 16.01.01, the mechanicalhydraulic system
is shown in Fig. 16.01.02, and the pneumatic sys-
tem, shown in Fig. 16.01.03.

Main Operating Panel (MOP)

In the engine control room a MOP screen is lo-
cated, which is a Personal Computer with a touch
screen as well as a trackball from where the engi-
neer can carry out engine commands, adjust the
engine parameters, select the running modes, and
observe the status of the control system.
A conventional marine approved PC is also lo-
cated in the engine control room serving as a
backup unit for the MOP.

Engine Interface Control Unit (EICU)

The EICU installed in the engine control room per-
form such tasks as interface with the surrounding
control systems, See Fig. 16.01.01.

Cylinder Control Unit (CCU)

The control system includes one CCU per one or
two cylinders. The CCU controls the electronic
fuel Valve Activitation (ELFI), in accordance with
the commands received from the ECS.
All the CCUs are identical, and in the event of a
failure of a CCU for two cylinders only these cylin-
ders will automatically be put out of operation.
It should be noted that any electronic part could
be replaced without stopping the engine, which
will revert to normal operation immediately after
the replacement of the defective unit.

Cooling Water Control Unit
On engines with load dependent cylinder liner
(LDCL) cooling water system, a cooling water
control unit (CWCU) controls the liner circulation
string temperature by means of a three-way valve.
Scavenge Air Control Unit
The scavenge air control unit (SCU) controls the
scavenge air pressure on engines with advanced
scavenge air systems like exhaust gas bypass
(EGB) with on/off or variable valve, waste heat
recovery system (WHRS) and turbocharger with
variable turbine inlet area (VT) technology.
For part- and low-load optimised engines with
EGB variable bypass regulation valve, Economiser
Engine Control (EEC) is available as an option in
order to optimise the steam production versus
SFOC, option: 4 65 342.
Engine Side Console (ESC)
In normal operating the engine can be controlled
from either the bridge or from the engine control
room.
Alternatively, the Engine Side Console can be ac-
tivated.
The layout of the Engine Side Console includes
the components indicated in the manoeuvring
diagram, shown in Figs. 16.01.04a and 16.01.04b.
The console and an electronic speed setting de-
vice is located on the camshaft side of the engine.
