Development of oil pump

The earliest engines used a drip feed system for oil - dropping it into moving parts and then collecting it in a tray underneath. On ships there was a position as ‘oiler’ whose job was to fill up little pots of oil above moving components. From around 1900 onwards, internal combustion engines moved to a forced-feed system , where oil is pumped around (forced) to the various parts of the engine. All modern engines use a fully forced-feed lubrication system and the key to this is the oil pump.

Where is the oil pump in an engine?

The oil pump is a highly critical part of the engine - if an oil pump stops working it will lead to expensive engine failure 100% of the time. That's one reason why the oil pump is so directly driven from the crankshaft. Oil pumps are situated in the oil pan, or more usually at the front of the engine.

What is the engine oil pump?

The oil pump is the heart of the lubrication system . It sucks oil up from the oil pan and forces it around oilways in the engine, before the oil drops back into the sump and is recirculated.

How does the oil pump work in an engine?

The oil pump is a part of an engine lubrication system that pumps oil under pressure. It pumps oil from the sump through the galleries to the rotating bearing, the sliding pistons and the camshaft of the engine. The primary purpose for the system is to pressurized oil lubricating oil to circulate within the engine moving parts.
