Technical Field

[0001] The utility model relates to a novel full-automatic cylinder oil mixing device, belonging to the technical field of cylinder oil supply systems for marine low-speed diesel engines. Background Art

[0002] Due to restrictions on emission regulations, modern marine low-speed diesel engines need to use low-sulfur fuel in emission control areas and some special areas, while conventional high-sulfur heavy fuel oil is used in other areas. According to the different sulfur content of fuel and the actual conditions in the diesel engine cylinder, the base value and injection rate of the cylinder oil should be continuously adjusted during the operation of the diesel engine to improve the acidity and alkalinity in the combustion chamber, ensure the normal operation of the cylinder, and avoid cold corrosion. For this reason, ships are generally equipped with two base value cylinder oils: one low base value cylinder oil and the other high base value cylinder oil. The cylinder oil supply system should be able to provide two types of cylinder oils and realize switching.
