    Abstract: The operation of marine diesel engines is improved through use of a defined fuel composition, containing one or more additives comprising a methal detergent, a non-metal detergent or both. The fuel is supplied to Diesel engines which operate in a maximum speed range of 1000 rpm (4-stroke engine) respectively 2500 rpm (2-stroke engine). The power output is greater than 200 bph. The cylinder bore is greater than 100 mm (2-stroke engine) while the piston stroke shall be greater than 150 mm (4-stroke engine) respectively greater than 120 mm (2-stroke engine). The metal containing detergent is a neutral calcium sulfonate, salicylate or calcium phenate. The non-metal containing detergent is a hydrocarbyl succinimide.

    Abstract: An overbased magnesium composition deposit control additive for residual fuel oils and turbine fuels is an overbased magnesium sulfonate, carboxylate or phenate or mixtures thereof containing at least 14% and upwards to about 18% by weight of magnesium and containing a succinic anhydride and lower carboxylic acid co-promoter reaction product. The additive when added to fuel oils, such as residual fuel oils containing high asphaltenes, reduces, if not eliminates, magnesium/asphaltene deposits or sediment and the consequential plugging of filters. The additive also reduces, if not eliminates, vanadium caused corrosion in the turbine. The invention is also the process for preparing the overbased composition or deposit control additive, wherein the overbasing reaction incorporates the combination of a lower carboxylic acid, preferably acetic acid and a succinic anhydride, preferably dodecenyl succinic anhydride (DDSA), as the co-promoter.

    Abstract translation: 用于残余燃料油和涡轮机燃料的高碱性镁组合物沉积物控制添加剂是高碱性磺酸镁，羧酸盐或酚盐或其混合物，其含有至少14重量％至约18重量％的镁并含有琥珀酸酐和低级羧酸 共促进剂反应产物。 当添加到燃料油中的添加剂，例如含有高沥青质的残余燃料油，减少（如果不消除）镁/沥青质沉积物或沉淀物以及由此导致的过滤器堵塞。 该添加剂还减少了如果不消除，钒在涡轮机中引起腐蚀。 本发明也是制备高碱性组合物或沉积物控制添加剂的方法，其中高碱性反应包含低级羧酸，优选乙酸和琥珀酸酐，优选十二碳烯基琥珀酸酐（DDSA）的组合，作为助催化剂 。
