Operation with Water Leakage into the Combustion
Chamber
1. General
If there is water leakage into the combustion chamber (e.g. a crack in the cylinder
cover or cylinder liner) the defective part must be replaced immediately.
2. Procedures
If it is not possible to replace the defective parts but the engine must continue to
operate, do the procedures on the related cylinder as given in steps 1) to 4):
1) Close the valves to the cooling water inlet and outlet of the related cylinder
(isolate the cylinder from the cooling system).
2) Drain the cooling water through the drain pipe.
3) Cut out the injection (see 0510−1, paragraph 1).
4) Lock the exhaust valve in the open position (see 0520−1, paragraph 3).
Note: If the cooling flow of the cylinder is stopped, there is a risk of that the
combustion chamber will overheat because of compression heat. Thus,
the exhaust valve must be opened to prevent damage to other
components.
After the procedures above are completed, the engine cannot operate at full load.
Read the data in 0500−1 General Information. Also, make sure that the exhaust gas
temperature is not more than 515_C on each cylinder.
Do not operate the engine for a long period after the emergency procedures are
completed.
The defective cylinder cover or cylinder liner must be replaced as soon as possible.
After this emergency operation is completed, see 0520−1 paragraph 3.2 for the
procedures to start the exhaust valve control unit.
