Performance under high temperature and high pressure - How does marine medium speed diesel engine oil protect the engine from excessive wear?
Publish Time: 2025-04-02
In the vast ocean, ships serve as bridges connecting the world, carrying the flow of goods and personnel. As the heart of the ship, the stable and efficient operation of marine medium speed diesel engines is the key to ensuring navigation safety and efficiency. However, under the harsh working conditions of high temperature and high pressure, the engine faces severe tests, and excessive wear becomes an important factor affecting the life and performance of the engine. In order to meet this challenge, marine medium speed diesel engine oil came into being, and with its unique performance and formula, it has become an important barrier to protect the engine from excessive wear.
1. The unique formula of marine medium speed diesel engine oil
Marine medium speed diesel engine oil is a high-grade marine oil based on deeply refined mineral oil. It is prepared according to a strict process formula by adding a variety of additives such as high alkaline calcium salt detergent, detergent dispersant, antioxidant, anti-corrosion agent, diffusant, anti-foaming agent, etc. These additives not only give the engine oil excellent lubrication properties, but also make it perform well under high temperature and high pressure.
High alkalinity calcium salt detergent is a key component in engine oil. It can effectively neutralize the acidic substances produced during engine operation, prevent acid corrosion and sludge formation, and thus protect engine parts from damage. Detergent dispersant can disperse solid particles and sludge in engine oil, maintain the cleanliness of engine oil, and reduce wear inside the engine. Antioxidants and anticorrosive agents can extend the service life of engine oil, prevent engine oil from oxidation and deterioration at high temperatures, and prevent corrosion of metal parts.
2. Protection mechanism of marine medium speed diesel engine oil
Under high temperature and high pressure working environment, marine medium speed diesel engine oil protects the engine from excessive wear through the following mechanisms:
Excellent lubrication performance: Engine oil can form a uniform lubrication film inside the engine, reduce direct contact between metal parts, and thus reduce friction and wear. Especially at high temperatures, the viscosity stability of engine oil is crucial, which can ensure that the engine oil can still maintain sufficient lubrication performance at high temperatures.
Good detergent dispersant performance: The detergent dispersant in engine oil can effectively disperse and remove sludge and carbon deposits inside the engine, preventing these impurities from causing wear to engine parts. At the same time, high alkalinity calcium salt detergent can also neutralize acidic substances to prevent acid corrosion.
Excellent anti-oxidation and anti-corrosion performance: At high temperatures, engine oil is prone to oxidation and deterioration, producing harmful substances. Antioxidants can inhibit the oxidation reaction of engine oil and extend the service life of engine oil. Anticorrosive agents can prevent corrosion of metal parts and protect the metal surface inside the engine from damage.
Good cooling performance: When the engine oil circulates inside the engine, it can take away some heat and play a cooling role. This helps to reduce the temperature of the engine and reduce the occurrence of thermal wear.
3. Application and maintenance of marine medium speed diesel engine oil
In order to ensure that the marine medium speed diesel engine oil can fully play its protective role, correct application and maintenance are essential. First, the appropriate engine oil model and specification should be selected according to the engine model and use environment. Secondly, the engine oil and oil filter should be replaced regularly to maintain the cleanliness and lubrication performance of the engine oil. At the same time, the viscosity, acid value and mechanical impurities of the engine oil should be checked regularly to ensure that the engine oil is in good use.
In addition, the maintenance of marine medium speed diesel engines also includes cleaning and inspection of the engine interior. Regularly cleaning the carbon deposits and sludge inside the engine, checking the wear of key components such as cylinder liners, piston rings, crankshafts, and timely replacing severely worn components are also important measures to extend engine life and reduce wear.
Marine medium speed diesel engine oil, with its unique formula and excellent performance, provides comprehensive protection for the engine under harsh working conditions of high temperature and high pressure. It can not only reduce engine friction and wear, extend the service life of the engine, but also improve the operating efficiency and reliability of the engine.
