Specific Cylinder Oil Consumption TierII
The figures given in this catalog represent values based on research as well as service experience.
For the MC,MC-C type engine, the cylinder lubricating system can be either the conventional mechanical lubricators (standard scope of supply) or electronically controlled Alpha lubricator system (option).
For the ME type engines, the Alpha lubricator system is equipped as standard scope of supply.
The Basic Setting of cylinder oil feed rate for the Alpha lubricating system can be reduced lower than that of conventional mechanical lubricators.
Furthermore, the Alpha lubricator system regulates the cylinder oil feed rate at partial load proportionally to MEP.

As the another control regulation for cylinder feed rate, the Alpha ACC (Adaptive Cylinder oil Control) can be selected, where the cylinder oil feed rate is adjusted depending on sulphur percentage (S%) in the fuel oil.
Furthermore, the cylinder oil feed rate at partial load is regulated proportionally to engine load.
