lentokoneöljyjä

Lentokoneöljyjä, also known as aviation lubricants, are specialized oils designed for use in aircraft engines. These oils differ significantly from automotive engine oils due to the extreme operating conditions experienced by aircraft engines, including high temperatures, pressures, and RPMs. They are formulated to provide superior lubrication, cooling, and cleaning while preventing corrosion and wear.

The primary function of lentokoneöljyjä is to reduce friction between moving parts within the engine, thereby minimizing heat generation and preventing component seizure. They also play a crucial role in transferring heat away from critical engine components to the oil cooler, helping to maintain optimal operating temperatures. Furthermore, these lubricants are engineered to suspend and remove combustion byproducts, sludge, and wear particles, keeping the engine clean and preventing blockages.

There are two main types of lentokoneöljyjä: mineral-based and synthetic. Mineral oils are derived from petroleum and are often used in older or less demanding engine designs. Synthetic oils, on the other hand, are chemically engineered to offer enhanced performance characteristics, such as better thermal stability, improved low-temperature flow, and greater resistance to oxidation. The choice of lentokoneöljy depends on the specific aircraft engine model, its operating environment, and the manufacturer's recommendations. Regular oil analysis is a common practice in aviation maintenance to monitor the condition of the oil and the engine.
