Description
Technical Field
The invention relates to a marine lubricating oil reinforcing agent, in particular to an old oil reinforcing agent for marine medium-speed engine oil.
Background
The marine engine can be divided into two-stroke and four-stroke according to stroke. The four-stroke engine is usually a plunger engine, the used lubricating oil is medium-speed engine oil, and the oil consumption is characterized by one-time filling and long-term use. Most of the fuels used in marine engines are heavy fuels, and the fuels contain more asphaltenes. In the event of an engine abnormality, poor combustion occurs, and heavy fuel leaks into the crankcase through the combustion chamber, causing a change in the performance of the lubricating oil.
Because the combustion chamber can generate high temperature and high pressure when fuel is combusted, carbon deposition is easily generated at the position of the piston head; meanwhile, the lubricating oil is also subjected to thermal decomposition under high temperature and high pressure, so that the lubricating oil is oxidized to generate oil sludge which is deposited on a crankcase to increase the viscosity of the lubricating oil, and the carbon deposit in the combustion process is easily subjected to abnormal abrasion on the cylinder wall and the crankshaft of the engine if not dispersed and separated by the lubricating oil in time.
Heavy fuels generally contain a certain amount of sulfur, and during combustion, acidic substances are easily formed when they encounter water, and not only are metal parts such as piston heads abraded, but also corrosion between piston rings and cylinder walls of engines is easily caused by the acidic substances. The detergent in the lubricating oil can effectively neutralize the acidic substances and protect the engine from corrosion. However, as the engine runs for a long time, the detergent is gradually consumed, and the neutralizing capability of the detergent on the acidic substances is gradually weakened, namely the base number of the detergent is continuously reduced.
For the reasons, after the marine medium-speed engine is operated for a period of time, the viscosity of the used medium-speed engine oil is generally increased, the base number is reduced, the content of insoluble substances in the oil is increased, and the cleanliness of the oil is also reduced. Generally, a ship lubrication manager replaces all the old medium-speed engine oil when an engine is maintained. Although this approach can effectively alleviate the use of lubricating oil, each new oil change incurs a portion of the cost, and a lane-entry cost is also required for the disposal of the waste medium speed oil.
Therefore, it is necessary to develop a medium speed engine oil enhancer which can effectively prolong the service life of the old medium speed engine oil.
