Õlivann

Õlivann is an Estonian term that translates to "oil pan" in English. It is a crucial component of an internal combustion engine, specifically an automotive engine. The primary function of the õlivann is to serve as a reservoir for the engine oil. This oil is vital for lubricating the moving parts of the engine, reducing friction, dissipating heat, and preventing wear.

The õlivann is typically located at the bottom of the engine, directly beneath the crankshaft. It is usually made of stamped steel or aluminum. The shape and design of the õlivann are engineered to hold a specific volume of oil and to facilitate its circulation throughout the engine. It often features a sump, which is the lowest point, where the oil collects before being drawn up by the oil pump.

In addition to storing oil, the õlivann also plays a role in cooling. As the oil circulates, it picks up heat from the engine components and carries it back to the õlivann, where it can dissipate into the surrounding air. Some õlivann designs may incorporate fins to increase surface area for better heat dissipation. A drain plug is typically located at the lowest point of the õlivann, allowing for easy draining of the old oil during routine maintenance such as oil changes. The õlivann's integrity is important for preventing oil leaks, which can lead to severe engine damage due to a lack of lubrication.
