摘要： Disclosed herein is a method for controlling supply of cylinder oil containing a base to a cylinder of a running large two-stroke crosshead engine, the large two-stroke crosshead engine having cylinders comprising a cylinder liner with a reciprocating piston therein, the method comprising: feeding the cylinder oil to the cylinder at a variable and controllable cylinder oil feed rate and with a variable and controllable basicity (TBN); adjusting the variable cylinder oil feed rate to an actual lubrication need of an inner surface of the cylinder liner; adjusting a total amount of detergent in the cylinder oil to an actual need for a presence of detergent in the cylinder liner; and adjusting a capacity to neutralize acidic combustion products in the cylinder resulting from an actual cylinder oil feed rate and basicity (TBN) by adjusting the basicity of the cylinder oil to an actual need of the inner surface of the cylinder liner for protection against acidic combustion products in the cylinder liner.

摘要： A blender (66) for batch blending an oil having a first TBN with a composition having a second TBN higher than the first TBN to produce a blended composition having a desired third TBN for use as a cylinder oil in a two-stroke compression ignited crosshead combustion engine (1). The blender (66) comprises an inlet port for receiving the oil and for receiving the composition, a discharge port for discharging said blended composition, a blending tank (63) with a tank inlet and a tank outlet.
