Elaborate the working of dry sump lubrication system with sketch.
Dry Sump Lubrication:
Working of dry sump lubrication system: In this system, the lubricating oil is not stored in oil sump .The oil from the sump is carried to a separate storage tank outside the engine cylinder block. The oil from sump is pumped by means of a scavenging pump through filter to the storage tank. Oil from storage tank. Oil from storage tank is pumped to the engine cylinder through oil cooler. Oil pressure may vary from 3 to 8 bar. Dry sump lubrication system is generally adopted for high capacity engines. The pressure relief valves are used to maintain the predefined pressure value inside the lubricating system
