Description

CF-4级柴油机油组合物用于船舶尾轴润滑的用途
技术领域
本发明涉及一种CF-4级柴油机油组合物用于船舶尾轴润滑的用途。
背景技术
随着柴油发动机技术的发展，比CF质量等级更低的CD级柴油机油不能满足某些发动机的用油要求。与CD级油相比，CF-4具有更好的高温抗氧性、清净分散性及抗磨性能，确保各种燃料状况下的发动机清洁，有效防止活塞环粘结延长发动机运转寿命，特别适用于燃料复杂(如硫含量较高)、低速大扭矩输出工况的发动机，如船舶主机、发电机组、推土机、挖掘机、采矿设备、装甲运输车辆等军用或民用柴油发动机。在兼顾发动机需求的同时，CF-4同时也可以满足船舶尾轴的需求，这可以大大简化船舶上的使用油品品种，优化产品线。
GB 11122-2006标准中规定CF-4发动机油必须通过L-38发动机试验轴瓦腐蚀试验、卡特皮勒1K、马克T-9、马克T-8A、康明斯腐蚀试验。
目前尚没有专利或文献记载柴油机油可用于船舶尾轴的润滑中。
