Sealing of the exhaust valve spindle guide is pro-
vided by means of Controlled Oil Level (COL), an
oil bath in the bottom of the air cylinder, above the
sealing ring. This oil bath lubricates the exhaust
valve spindle guide and sealing ring as well.
Indicator Cock
The engine is fitted with an indicator cock to
which the PMI pressure transducer is connected.
MAN B&W Alpha Cylinder Lubrication
The electronically controlled MAN B&W Alpha
cylinder lubrication system is applied to the ME
engines, and controlled by the ME Engine Control
System.
The main advantages of the MAN B&W Alpha cyl-
inder lubrication system, compared with the con-
ventional mechanical lubricator, are:
• Improved injection timing
• Increased dosage flexibility
• Constant injection pressure
• Improved oil distribution in the cylinder liner
• Possibility for prelubrication before starting.
More details about the cylinder lubrication system
can be found in Chapter 9.
Gallery Arrangement
The engine is provided with gallery brackets,
stanchions, railings and platforms (exclusive of
ladders). The brackets are placed at such a height
as to provide the best possible overhauling and
inspection conditions.
Some main pipes of the engine are suspended
from the gallery brackets, and the topmost gallery
platform on the manoeuvring side is provided with
overhauling holes for the pistons.
The engine is prepared for top bracings on the ex-
haust side, or on the manoeuvring side.
Piping Arrangements
The engine is delivered with piping arrangements
for:
• Fuel oil
• High pressure gas supply
• Heating of fuel oil
• Lubricating oil, piston cooling oil, hydraulic oil
and sealing oil for gas valves
• Cylinder lubricating oil
• Cooling water to scavenge air cooler
• Jacket and turbocharger cooling water
• Cleaning of turbocharger
• Fire extinguishing in scavenge air space
• Starting air
• Control air
• Oil mist detector (required only for make
Schaller Automation)
• Various drain pipes.
All piping arrangements are made of steel piping,
except the control air and steam heating of fuel
pipes, which are made of copper.
The pipes are provided with sockets for local
instruments, alarm and safety equipment and,
furthermore, with a number of sockets for supple-
mentary signal equipment. Chapter 18 deals with
the instrumentation.
