汽车机油型号简述

汽车机油型号简述 汽车机油型号简述(2009-01-15 21:13:39)标签:汽车 现在的汽车用的机油大部分是冬夏通用的，这里简单说明型号的组成。 例SAE5W-40(粘度表) SAE:是英文“美国汽车工程师协会”的缩写 5W:“W”表示winter(冬季)，其前面的数字越小说明机油的黏度越稀，流动性越好，代表可供使用的 温度越低，在冷启动时对发动机的保护能力越好。 5w -30?C 、10w -25?C 、15w -20?C 、20w -15?C -40: 机油耐高温性的指标，数值越大说明机油在高温下的保护性能越好。较高黏度的机油对运动系的阻力 也相对较高，不但耗费功率、增加油耗，而且机油容易氧化、影响冷启动的保护。 30 30?C 、 40 40?C 、50 50?C 例API SJ(品质) API :美国石油学会的英文缩写 S: 表示汽机油(C表示柴机油) J: 从“SA”一直到“SL”,每递增一个字母，机油的性能都会优于前一种，机油中会有更多用来保护发 动机的添加剂。字母越靠后，质量等级越高，国际品牌中机油级别多是SF级别以上的。 朋友们更换机油的时候根据车辆使用的地区及强度选择就可以了。www.socpj.com找所有经销商，找北京最低价。 关于机油的基础知识、合理使用及答疑 -------------------------------------------------------------------------------- 汽车之家 类型:原创 日期:2009/01/06 汽车之家 责任编辑:韩路 [汽车之家 技术] 机油一直是很多汽车用户熟知的一个词汇，那到底机油是干什么用的呢,那些标号代表什么意思,什么车适合用什么机油最合适,今天汽车之家编辑为您进行详细的讲解:(本文仅以汽油发动机用的机油作为主要讨论目标) ? 机油的作用: introduced a number of leading creative talents, and then the "introduction of a high-end talent, bringing an innovative team, a mainstay of the economy," the derivative effect, improving the competitiveness of inner.
