加圧潤滑

エンジンの可動部分に 1 つまたは複数のポンプから潤滑油が供給されるシステム。

3.1.4

重力給油

重力の影響下でエンジンの可動部分に潤滑油が供給されるシステム

3.1.5

3.2.1

main running gear lubrication

any type or combination of lubricating systems in which the crankshaft bearings, connecting rod bearings, piston-pin bearings, crosshead guiderails, bearings and guideways of the valve gearing, and in some cases also the cylinders and the piston slideway of the cylinders, are supplied with lubricating oil

3.2.2

dip lubrication

non-pressurized lubricating sys­tem in which the lubricating oil is taken from the sump or oil pan by dipping moving parts (e.g. dipper on connecting rod) and is thrown into the crankcase and/or into the bearings

3.2.3

wet sump force-feed lubrication

force-feed lubricating system in which the lubricating oil is collected in the engine sump, which serves as a lubricating oil tank

3.2.4

dry sump force-feed lubrication

force-feed lubricating system in which the lubricating oil is collected in a separate lubricating oil tank. The oil is continuously scavenged from the engine sump and passed back to the lubricating oil tank

Note 1 to entry: The illustration shows a lubricating system with an oil pan which has an intermediate lubricating oil chamber. Usually, in dry sump systems, lubricating oil is collected in a separate lubricating oil tank.

3.2.5

splash lubrication

method of lubricating the engine by relying on lubricating oil thrown by moving parts of the engine

3.2.6

cylinder lubrication

any type or combination of lubricating systems for specially supplying the cylinder liners with lubricating oil

3.2.7

supplementary lubrication

any method of lubricating engine parts to increase the supply of lubricating oil

3.2.8

independent lubrication

any method of lubricating the engine parts in which all the lubricating oil is supplied from a source that is independent of the engine

3.3.1

lubricating oil filter

filter in which the liquid filtered is lubricating oil

3.3.2

lubricating oil suction strainer

coarse filter at the entry to the lubricating oil pump suction pipe

3.3.3

single-stage lubricating oil filter

filter in which the lubricating oil passes through only one grade of filter element

3.3.4

two-stage lubricating oil filter

filter which incorporates two types of filter element filtering in series, one of which is coarse and the other fine

3.3.5

rotating centrifugal lubricating oil filter

centrifuge

filter for separation by centrifugal force

3.3.6

full-flow lubricating oil filter

filter through which is passed the whole of the quantity of lubricating oil delivered to the lubricating system

3.3.7

bypass lubricating oil filter

filter through which is passed a part of the quantity of lubricating oil delivered to the lubricating system

3.3.8

spin-on cartridge lubricating oil filter

filter consisting of a replaceable assembly with an integral filter element screwed directly into or onto a lubricating system; the assembly may include the filter element bypass component and the anti-drain valve

3.3.9

duplex lubricating oil filter

two parallel lubricating oil filters connected by a valve. In order to clean one filter element, the lubricating oil flow is directed through the other filter element. No interruption of the operation is necessary

3.3.10

back-flushing lubricating oil filter

filter in which the cleaning of the disconnected filter elements in the filter takes place by reversing the direction of flow (back-flushing). No interruption of the operation is necessary

3.3.11

automatic lubricating oil filter

filter in which the cleaning of the filter elements is done automati­cally. No interruption of the opera­tion is necessary. The cleaning procedure can be started manually (semi-automatic) or by a contactor (fully automatic)

3.3.12

lubricating oil pump

pump providing the force-feed circulation of the lubricating oil and its delivery to the moving parts of the engine

3.3.13

lubricating oil scavenging pump

pump which draws lubricating oil from the engine sump and pumps it into the oil tank on dry sump engines

3.3.14

lubricator

pump which supplies a given quantity of lubricating oil periodically to specific parts of the engine

3.3.15

oil pressure relief valve

valve to prevent the lubricating oil pressure in the lubricating system from rising above a predetermined value

3.3.16

oil pressure regulating valve

valve which regulates the lubricating oil pressure in any part of the lubricating system to a predetermined value

3.3.17

oil level indicator

component or system, such as a sight glass, window nut, remote reading gauge, etc., which indicates the lubricating oil level

3.3.18

dipstick

stick with graduation marks, located in the oil tank or oil sump, for checking the quantity/level of lubricating oil in the engine

3.3.19

oil pressure gauge

component used to indicate and measure the lubrication system oil pressure

3.3.20

lubricating oil tank

vessel which acts as a reservoir from which the lubricating oil pump draws lubricating oil. The tank may be formed by the engine sump (wet sump system) or may be a separate vessel (dry sump system)

3.4.1

filter housing

part of a filter, the purpose of which is to locate the filter element or filter insert

3.4.2

filter cover

part of a filter, the purpose of which is to close the filter housing and to clamp the filter element

3.4.3

filter element

part of a filter, the purpose of which is to retain the insoluble contaminant

3.4.4

filter insert

combination of a filter element (or several elements) with supporting parts

3.4.5

rotor

drum

the part of a rotating centrifugal lubricating oil filter where the filtering takes place (the term “rotor” is used in separately driven centrifuges and “drum” in free jet centrifuges)

3.5.1

3.5.2

cylinder oil

lubricating oil which is supplied directly to the inside surface of the engine cylinders independently of the main engine lubrication system, particularly for larger engines

3.5.3

system oil

lubricating oil which is supplied (e.g. to bearings, oil cooled pistons) independently of the cylinder oil system
