Lubrication is a system which all the motoring engine components
require to be lubricated, in order to prevent the direct friction between
components that cause fatal defect. In fuel motor lubrication is done to all
moving parts thoroughly, therefore required maximal pressure in supporting
generator diesel activities. Tekanan harus mencapai nilai 4,0 – 4,5 kg/cm2 untuk
mencapai pelumasan yang maksimal. The pressure have to reach grade 4,0-4,5
kg/cm2. This part to preventing if auxilary engine is overloaded so the pressure
not to close the bad lubricating limitation and alarm occcurs on the pressure 3,7
kg/cm2. The writter formulates the issue by research the factors of decline of the
liner sylinder system lubrication, the impact of the decline of the liner sylinder
system lubrication, and effort which is done to handle the decline of the liner
sylinder system lubrication.
The writter resumes the issues and solve the problem by using observation
method directly, interview, documentation, and literature review to get the data
which is related to diesel generator that usefull to support the writing fluency in
minithesis making.
There are many causes in less of the optimal of lubrication system
maintenance on generator diesel. Amongst which is happened on the MV. Energy
Prosperity, from he causes which is founded. On the MV. Energy Prosperity less
of the lubrication sytem optimality so the lubricate oil pressure abnormal is
caused by the problem on main bearing and crank pin bearing, the high
temperature of lubricate oil and problem in the pump that very impact to
lubrication oil system.
