摘　　要：为降低大型船用低速二冲程柴油机气缸油实船试验的风险,基于6S35ME-9型船用柴油机试验台架,把气缸油系统分为三组：1^#与2^#气缸使用试验油A、3^#与4^#气缸使用参比油、5^#与6^#气缸使用试验油B,在标定工况下运行,通过试验过程评价、气缸油清净分散性评价、气缸套与活塞环组件磨损量和油品光谱检测为指标的抗磨性评价、柴油机关键参数评价、与参比油对比等综合评定,确定试验油的优劣。结果表明：对于三种油品,气缸套、活塞环和活塞环槽的磨损量与通过气缸油残油检测的金属元素含量判断的磨损状况相比二者具有一致性,结合气缸油的清净分散性评定结果,可有效判断油品是否可以进行实船试验。同时,在试验过程中油品中Fe、Cr元素含量60 h后趋于平衡,因此设定台架试验时间为100 h。经以上方法评定的气缸油,经实船试验符合要求。因此,基于该台架试验对气缸油的评定方法是可行的、经济的。To reduce the risk of ship sailing tests for the cylinder oil of large low-speed two-stroke marine diesel engines,a test bench equipped with a 6S35ME-9 type marine diesel engine was used,and the cylinder oil system was divided into 3 groups： Cylinders 1 and 2 corresponded to testing oil A,3 and 4 corresponded to a reference oil,and5 and 6 corresponded to testing oil B. Under given working conditions,the tested oils were subjected to comprehensive evaluation,including testing process evaluation,clean dispersancy evaluation,and resistance-to-abrasion evaluation according to cylinder and piston ring wear and oil spectrum analysis,assessment of critical diesel engine parameters,and comparison with reference oil. The results show that,for the three types of oil,the measured wear values of cylinder liners,piston rings,and piston grooves are consistent with the amounts of metal found in the residual cylinder oils. By combining the above results with the estimated cylinder oil dispersancy,we can determine whether a cylinder oil can be used in ships. In addition,because the Fe and Cr contents in the residual cylinder oil are balanced after 60 h,100 h is suitable for bench testing. Cylinder oil assessed by the above method is proved to be satisfactory by actual ship tests. Therefore,the proposed bench testing method for cylinder oil estimation is feasible and economical.
