1. Definition of Oil Sump

An oil sump is at the bottom of an internal combustion engine and collects, stores and supplies engine oil for lubrication. It’s a housing for the oil after it’s been through the engine, where it cools and settles before the oil pump recirculates it. The oil sump also traps impurities so the engine runs smooth and doesn’t wear out.

1.1 Role of Oil Sump in the lubrication system of an internal combustion engine

The oil sump is part of the lubrication system of an internal combustion engine. It’s a storage tank for engine oil so there’s a constant supply for lubrication. The oil sump collects oil after it’s been through the engine, where it cools and settles impurities. It gives the oil pump access to the stored oil which is then pressurized and distributed to lubricate engine components like crankshaft, camshaft and pistons. This cycle reduces friction, minimizes wear and regulates engine temperature for better performance and longevity.
