Oil pump (internal combustion engine)

From Wikipedia, the free encyclopedia

This article is about a part in an internal combustion engine. For other uses, see Oil pump.

The oil pump in an internal combustion engine is usually a gear pump driven by the camshaft or crankshaft. [1] Oil pressure varies quite a bit during operation, with lower temperature and higher RPM's increasing pressure to a maximum of about 4 bar. To ensure that the oil pressure does not exceed the rated maximum, a spring-loaded pressure relief valve routes oil back to its source once pressure exceeds a preset limit.[2]

The oil pump usually sucks the oil out of the engine's oil pan through a wire mesh strainer and pumps the oil through an oil filter before it goes to the bearings. oil pump
