How does temperature affect the lubrication of the main engine?

Higher temperatures lead to a reduction in the effectiveness of lubrication in the main engine. As temperature increases, the viscosity of the lubricating oil typically decreases, which means the oil becomes thinner and less capable of forming a protective film between moving parts. This can result in insufficient lubrication, leading to increased friction and wear on engine components.

Additionally, elevated temperatures can contribute to the breakdown of the oil's molecular structure, reducing its ability to lubricate effectively over time. This is particularly critical for engines, where proper lubrication is vital for maintaining operational efficiency and prolonging the lifespan of the mechanical parts. Thus, understanding the impact of temperature on lubrication helps in selecting appropriate lubricants and operating conditions to maintain engine performance.
