oljepannen

Oljepannen, also known as the oil pan or sump, is a critical component of an internal combustion engine. Its primary function is to serve as a reservoir for the engine's lubricating oil. This oil is essential for reducing friction between moving parts, cooling the engine, and preventing wear. The oil pan is typically located at the bottom of the engine, beneath the crankshaft.

The construction of an oil pan usually involves sheet metal, often steel, though aluminum is also used in some applications for weight reduction. It is designed to be a sealed unit, preventing oil from leaking out and contaminants from entering. Inside the oil pan, there is often a baffle or windage tray. This component helps to prevent oil from sloshing excessively, especially during high-speed maneuvers or cornering, ensuring a consistent supply of oil to the oil pump pickup.

An oil pickup tube extends from the oil pump down into the oil pan, drawing oil from the lowest accessible point to ensure maximum lubrication. The oil pan also typically contains a drain plug, allowing for the removal of old oil during routine maintenance such as oil changes. The capacity of the oil pan varies depending on the engine size and design, but it holds enough oil to keep the engine lubricated for its intended operating period. Proper maintenance of the oil pan, including ensuring it is free from cracks or leaks and that the drain plug is secure, is vital for the longevity and performance of an engine.
