again for the second half of cylinders (eg
cylinder 4 and 5 or 4 to 6).
3.1.7
Open all shut-off valves (001) in the cylinder cover supply pipes.
3.2
For an engine without a bypass cooling water system (refer to
), and
when the liner wall temperature is between 60°C and 90°C (eg when the engine
is pre-heated or after engine full stop for a sufficient period), release the unwanted
air with a high flow rate as follows:

3.2.1
Close the shut-off valves (001) in the cylinder liner supply pipes of the first
half of cylinders (eg cylinder 1 to 3 for a 5 or 6 cylinder engine).
NOTE:
This increases the pressure and thus the flow rate to the other
cylinders.
3.2.2
Let the cooling water flow through the other cylinder liners for
approximately ten minutes.
3.2.3
Open the shut-off valves (001) in the cylinder liner supply pipes of the first
half of cylinders.
3.2.4
again for the second half of cylinders (eg
cylinder 4 and 5 or 4 to 6).
3.3
Set all valves to their correct positions for operation.
3.4
Release the unwanted air in the cooling water pipes and the scavenge air coolers
at the related vent valves.
3.4.1
Carefully open the first vent valve.
3.4.2
After water that has no air flows out, close the vent valve.
3.4.3
again with the other vent valves.
3.5
Make sure that the values that follow are in the permitted range:
•
Pressure in the supply pipe of the cylinder cooling water
•
Temperature in the supply pipe of the cylinder cooling water
•
Pressure in the cooling water supply pipe of the scavenge air cooler (SAC)
•
Temperature in the cooling water supply pipe of the SAC.
