An oil filter is a vital engine component that removes contaminants such as dirt, metal particles, and sludge from the engine oil. Clean oil is crucial for lubricating engine parts, reducing friction, and preventing wear.

In the context of engines and machinery, sleeves (often called cylinder sleeves or liners) are components that line the interior of the engine’s cylinder. They provide a durable, replaceable surface for the piston to move within, protecting the cylinder from wear and reducing friction.

A turbocharger is a forced induction device that increases an engine’s efficiency and power by compressing air entering the engine. It uses exhaust gases from the engine to spin a turbine, which drives a compressor that forces more air into the engine’s combustion chamber.
