Copper nanoparticles were modified by surface modifier, methyl - methylacrylate, and minified by use of fluid-flow comminuted method, the disper sity and dispersion stability of the modified copper nanoparticles as additive i n CD 15W/40 engine oil were evaluated by high velocity centrifuger; its morpholo gy and particle size were tested by TEM and XRD analysis; and its tribological p roperty in CD 15W/40 engine oil was investigated by ball on pan tribo-tester.

采用化学改性法与液流粉碎机械法对纳米铜微粒进行了表面改性和分散研究，采用高速离心机考察了表面改性后纳米铜微粒作为添加剂在CD15W/40柴油机油中的分散性及分散稳定性，采用TEM、XRD测试了表面改性纳米铜微粒的形貌及粒径大小，采用球盘磨损试验机考察了表面改性纳米铜微粒作为CD15W/40全配方调配油添加剂的摩擦学性能，用SEM、EDS观察了磨损表面的形貌、线扫描、面分布及元素含量，分析了纳米铜微粒在摩擦过程中的减摩润滑机理。结果表明：甲基丙烯酸甲酯化学改性结合液流粉碎方法处理后纳米铜微粒的粒径进一步均匀、细化，平均粒径为24nm，并在CD15W/40油中分散性好，悬浮稳定时间长。

At notaries notarization, the motor without oil for traveling 4018 kilometers, has created a new domestic record.

Shortly after Mobil lost their lawsuit, most oil companies started reformulating their synthetic oils to use Group III base stocks instead of PAOs or diester stocks as their primary component.

在Mobil 输掉这场诉讼之后，多数机油厂商开始在他们的全合成油使用GROUP III石油基础油，来取代PAOs 或Polyol Esters作为他们的主要组分。

Every four seconds of every day, 1,200 cars fill their tanks with petrol on Shell forecourts, while at airports around the world civil airliners are refuelled with Shell aviation spirit every ten seconds.

每四秒钟全世界就会有1200辆汽车在壳牌公司散布全球各个角落的大大小小加油站里往自己的车箱里注入汽油，在分散在世界各地的机场里，每十秒钟就会有民航客机用壳牌民航机油加油。

Technologies, as well as oil change intervals prolonged. Oils were required with higher smuts

1998年采用高压、延迟喷射技术，同时换油期的延长加重了烟炱对机油的污

The system, has been adopted worldwide for engine oil viscosities.

该系统在全球范围内被用来对发动机油粘度分级。

At present, the main production engine timing belt cover, cold air intake box assembly, isolators, oil port cover, retaining tube stents, water blocks, outlet, bowl gaskets, intake air temperature sensor plug and universal joints Dustproof, aluminum die-casting products.

目前主要生产发动机正时皮带罩、冷空气进气箱总成、隔离器、机油口盖、护管支架、进水座、出水口、碗形垫片、进气温度传感器堵头及万向节防尘罩、铝压铸等产品。

They produced oil for artificial asphalt, machine oil and lubricants, in addition to ?ukasiewicz's kerosene lamp.

他们生产的人造石油沥青，机油和润滑油，除了卢卡西维茨的煤油灯。

Barium sulfona te and barium soap of petroleum ester oxide were dissolved in kerosene or machin e oil to prepare oil-soluble corrosion inhibitor.

将石油 磺酸钡和氧化石油脂钡皂溶于煤油或机油中制得缓蚀剂。
