现在柴油机在船舶上使用的相当普遍。在一艘船舶的动力装置中常常采用转速、强化程度以及工况等参数各不相同的柴油机。柴油机的这些状况往往决定着对润滑的要求水平。有时不得不在一个动力装置中采用不同牌号的机油,甚至采用那些不能保证发动机良好工作的机油。 所有这些都表明迫切需要压缩机油品种,制定统一的规格和评定机油是否适用于某种发动机的统一标准。 如今的工作是对若干现行评定标准进行分析,并提出一些新的评定标准。照我们看来, Diesel engines are now quite common on ships. In a ship’s power plant often used speed, degree of strengthening and working conditions and other parameters of different diesel engine. These conditions of diesel engines often determine the level of lubrication requirements. Sometimes it is imperative to use different grades of motor oil in one powerplant, even those that do not guarantee good engine work. All of this shows that there is an urgent need to compress oil varieties, develop uniform specifications and assess whether oil is amenable to a single standard for a given engine. Today’s work is to analyze a number of existing assessment standards and to propose some new assessment standards. In our opinion,
