An Alpha Lubricator or ME Lube operating in ACC-mode (Adaptive Cylinder oil Control) adapts the lubricating oil feed rate to the fuel oil sulphur content and the engine load.
The ACC-mode has been the standard on MAN B&W two-stroke engines since 2004. This cylinder lubrication, shown in the figure is based on a lubricator which injects a specific volume of oil into each cylinder for each (or for every second, third, etc.) revolution.
