Performance Analysis of the Main Engine Lubrication System of FV. Trans Mitramas 5
Abstract
The lubrication system in diesel engines is very important in ensuring engine performance, durability, and efficiency. Without an optimised lubrication system, diesel engine components can wear out quickly, the engine can easily overheat, and its performance will decrease. Eventually, this will shorten engine life and increase maintenance and repair costs. This research aims to analyse the performance of the lubrication system in the main engine, especially at the pressure and temperature. The method used is the observation method, with data collection techniques carried out by systematically observing and recording phenomena that occur at the pressure and temperature of the lubricating oil and the lubricating oil cooling water. The engine is a Hansin diesel engine with six cylinders and 2000 HP. Data was taken at 165-200 rpm. The average temperature of the lubricating oil out of the main engine is 69oC after being cooled by the oil coller, the temperature of the lubricating oil drops to 52oC, with a lubricating oil pressure of 2.1 kg/cm². The cooling process results in the lubricating oil temperature being reduced by 17oC. Lubricating oil cooling in diesel engine operations can be considered less than optimal because ideally the temperature of lubricating oil according to the manual book ranges from 37-47ºC after being cooled by seawater. From these conditions, it is necessary to maintain the lubrication system, especially the oil cooler.
