Key Functions of Aircraft Oil:<\/p>\n

    \n
  1. Lubrication<\/strong>: Creates a thin film between moving parts to reduce wear and friction.<\/li>\n
  2. Cooling<\/strong>: Transfers heat away from hot engine components, acting as a primary cooling system that can handle up to 50% of the total engine cooling needs.<\/li>\n
  3. Cleaning<\/strong>: Picks up contaminants (dirt, carbon, metal particles) and carries them to the filter or holds them in suspension until an oil change.<\/li>\n
  4. Sealing<\/strong>: Aids in forming a seal between the piston and cylinder walls to prevent combustion gas leakage.<\/li>\n
  5. Corrosion Prevention<\/strong>: Leaves a protective coating on internal engine parts to prevent rust and corrosion when the engine is not in use.<\/li>\n
  6. Actuation<\/strong>: In some systems, it acts as a hydraulic fluid to control propeller pitch or adjust turbocharger wastegates.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
