Abstract
The main engine is part of a ship because the main engine functions as the main driver of the ship that rotates the propeller so that the ship can move. In the operation of the ship's main engine, there are several systems to support the performance of the engine itself, including the lubrication system. Lubricating oil is a liquid used as a lubricant in the engine to reduce wear due to friction, as a coolant, and as a sound dampener. However, high temperatures in the engine will damage its viscosity if the viscosity of the lubricant decreases. The heat generated increases so that the temperature continues to increase. The normal lubrication temperature is 45 ° C-50 ° C and the abnormal temperature is 50 ° C-70 ° C. The rising oil temperature can be caused by a lack of heat absorption in the lubricating oil cooler and can also be caused by the volume of cooling media entering the lubricating oil cooler not being comparable to the lubricating oil being cooled. To obtain data, the author uses various methods, namely observation, interviews and literature studies. From the results of observations, it can be seen that the cause of the increase in the temperature of the lubricating oil is caused by the cooler, pump, oil filter. If the temperature of the lubricating oil rises, maintenance or repairs must be carried out on the lubrication system so that the temperature of the lubricating oil returns to normal. It is recommended to always monitor the temperature of the lubricating oil, input and output pressure on the L.O Cooler so that there is no increase in the temperature of the lubricating oil in the lubrication system of the main ship's engine. Keywords: lubricating oli, temperature, ship engine
