MAINTENANCE OF DIESEL ENGINES



The reliability and safe working of marine diesel engine depends upon the technical staff and in particular upon sea going engineers.



Planned maintenance of marine machinery can prolong its life. Engine builders, pump makers, in short all the makers of the equipment in ship provide instruction about the regular care and maintenance to be given to their equipment, with information and knowing the continuous survey requirement, the chief engineer plans the voyages maintenance work.



On board ship every engineer is delegated with the responsibility for the efficient running and maintenance of various items of machinery. Duties and responsibilities are clearly defined and are not to be left any uncertainity.



GENERAL MAINTENANCE INSTRUCTION

1. trained and qualified personnel must operate diesel engines only. Unauthorized people must not allowed to operate the engine

2. a logbook should be kept for each engine, in which all important data and work concerning the engine (eg number of running hours each day, actual fuel consumption, intervals between oil changes, pressure and temperature of engine and general performance remarks about machinery) are written .this provide useful information when irregularities or trouble occur.

3. the safety regulations and instruction concerning safety measures to be observed during operation, maintenance and repair work.

4. all essential parts of engine should be overhauled and cleaned up at regular intervals as per makers’ maintenance schedule. In order to keep the engine in good condition and constant operational readiness.

5. A part from others factor the frequency of overhauls of various engine parts is determined by the load at which the engine is normally run and by the grade of fuel and lubricating oil used.

6. overhaul jobs should be carried out only with the special devices and tools normally supplied with engine. The use of inappropriate tools will cause loss of time and damage to engine parts.

7. all parts overhauls during maintenance work to be checked for correct functioning before they are put into operation again particularly pipes must be pressure tested for possible leaks.

8. after the completion of the overhauls or maintenance work the engine should be cleaned with cleaning cloths (not by cotton rags or wool). Petrol should not be used for cleaning in closed rooms because of danger of explosion.

9. for putting the engine into operation after overhauling or maintenance work, turn the engine over by hand or with the turning gear for checking that all moving parts are moving freely.

10. to fill empty starting air bottle ( for starting engine) no other gases are to be used than air or carbon dioxide, even in emergency. In particular, oxygen or hydrogen must not be used, as this would expose the personnel and the engine to very danger.

11. engine must always have a reverse output hence it is advisable in continuous operation to limit the output to 85 t
