What is the definition of a dry sump?

[ClaytonLynn]

Instead of installing an oil container at the bottom of the engine, an independent oil tank is installed externally, and an oil pump is used to provide pressure lubrication to the crankshaft and connecting rod system. This is known as a dry sump. More information about dry sumps is as follows: 1. Introduction: Dry sump technology first appeared in the 1930s and was applied to small motorcycles to improve lubrication performance. Over the decades, with the development of motorsports, this technology has become increasingly understood and recognized, especially in the fields of racing and car modification. 2. Enhanced engine lubrication performance: Since the oil entering the main oil passage of the engine comes from the oil tank rather than directly from the oil pan, the oil used for lubrication is of better quality, with higher pressure and more stable flow, thereby improving the lubrication effect on the engine. This advantage is particularly evident in endurance races.
