These chemical compounds perform a variety of functions, including preventing the oil from breaking down at high temperatures (thermal stability), inhibiting rust and corrosion on internal metal surfaces, and maintaining the correct viscosity in cold weather. Keeps oil galleries clear for proper flow.
Engine Lubrication Basics: How Oil Protects Moving Parts
Additionally, oil forms a protective layer on cylinder walls, preventing combustion byproducts and corrosive acids from etching and damaging the metal surfaces. Extends the lifespan of critical engine parts.
Sealing and Combustion Chamber Protection Beyond moving parts, oil plays a vital role in sealing the combustion chambers. It moves through a complex network of passages, coating every moving part to reduce friction and prevent the metal components from grinding against each other.
Engine Lubrication Basics: Keeping Oil Galleries Clear and Reducing Friction
Managing Heat and Engine Temperature While the coolant system handles the bulk of temperature regulation, oil plays a significant supporting role in managing heat. The Core Function: Lubrication and Friction Reduction The primary role of car oil is to create a thin, slippery film between moving metal surfaces.
