Sump
|
The sump is at the base of an engine. It can be used as a storage container in a “wet sump system”.
|
Oil collection pan
|
An oil collection pan is used in “dry sump systems” prior to being returned to an oil tank.
|
Oil tank
|
An oil tank is used for storage of oil.
|
Pickup tube
|
A pickup tube is used to provide a means of collecting oil for the oil pump.
|
Oil pump
|
Oil pumps deliver oil under pressure to the internal engine parts. In a rotor-type oil pump, an inner rotor drives an outer one. Pressure differences force the oil to move. Geared oil pumps use a similar principle.
|
Oil pressure relief valve
|
The pressure relief valve is used to prevent damage to an engine due to too much oil pressure.
|
Oil filters
|
The oil filter helps to clean the oil in the system. If the filter clogs, a valve opens and directs unfiltered oil to the engine. Most oil-filters on diesel engines are larger than those on similar gasoline engines.
|
Spurt holes & galleries
|
Spurt holes and galleries are used to deliver oil from the oil pump to various components and bearings in the engine.
|
Oil indicators
|
Oil indicators are used to check when there are safe oil levels in an engine.
|
Oil cooler
|
An oil cooler cools oil prior to its reuse in the engine. |
