Argina T 40

In use, the TBN will fall from its aegina value over a period of several hundred hours until it reaches an equilibrium level, where it will remain indefinitely unless conditions change. The influence of these factors is illustrated schematically in Figure 1.

The equilibrium value which is established thus depends both on the 4t0 sulphur content and the oil consumption of the engine. For satisfactory centrifugal separation, it is particularly important to: Purification During use, water may obtain access to the lubricating oil due to leakage from oil coolers or other sources.

Minimum Equilibrium TBN With a multi-functional additive system, the TBN is a measure not only of acid neutralisation capability, but also detergency — the ability to keep the piston ring belt free from deposits.

Operate the machine continuously.

In the absence of such advice, it is recommended the minimum equilibrium TBN should not fall numerically below four times the fuel sulphur content. Approvals Shell Argina T Oil is approved by all leading manufactures of medium speed diesel engines.

Many engine manufacturers specify the minimising equilibrium TBN level above which satisfactory engine wear and cleanliness will be obtained, and their advice should be followed.

Specifications Medium Speed Piston Diesel Engines Oils Applications Shell Argina T Oil is premium quality oil specifically developed to lubricate these engines and is suitable for use with fuel with a sulphur content of 1.

With a multi-functional additive system, the TBN is a measure not only of acid neutralisation capability, but also detergency — the ability to keep the piston ring belt free from deposits. At the equilibrium level, the alkalinity taken into the engine by the top-up oil just neutralises the acid generated by combustion and carried on to the cylinder walls. The upper Curve 1 indicates what would be expected from a fuel of lower sulphur content in an engine with a higher sulphur content enhanced by an engine with low oil consumption, would be to establish an equilibrium TBN at a lower level as shown by Curve 2.

During use, water may obtain access to the lubricating oil due to leakage from oil coolers or other sources. Medium Speed Piston Engines.

Shell Argina T Oil is premium quality oil specifically developed to lubricate these engines and is suitable for use with fuel with a sulphur content of 1. Normal purification equipment and practices are recommended for the removal of water and other contaminants in Shell Argina T Oil.

Equipment should, of course, be operated in accordance with the manufacturers instructions.
