õlivannist

õlivannist is an Estonian term referring to the oil pan, also known as the sump, of an internal combustion engine. This component is a crucial part of the engine's lubrication system. Its primary function is to store the engine oil when the engine is not running. When the engine is active, the oil pump draws oil from the õlivannist to circulate it throughout the engine, lubricating moving parts, reducing friction, and helping to dissipate heat.

The õlivannist is typically located at the bottom of the engine, forming a reservoir. It is usually made of stamped steel or sometimes aluminum. Modern õlivannists often incorporate features such as baffles to prevent oil surge during acceleration and braking, and a drain plug for easy oil changes. The design and capacity of the õlivannist vary depending on the engine's size and application. Regular checks of the oil level in the õlivannist are essential for maintaining engine health and preventing damage.
