发布者: 发布时间:2016-02-10 浏览量:

 (1)机油亦可称做何种油?

    Oil can also be called what kind of oil?

  发动机油、马达油 

 Engine oil, motor oil

(2)汽机油中SC SD SE SF SG SH SJ EC有何含义?柴机油中CC CD CE CF-4 CG-4有何含义? 

 SC SD SE SF SG SH SJ EC What is the meaning? What is the meaning of CC CD CE CF-4 CG-4 in diesel oil?

  SC SD SE SF SH SJ EC是美国石油学会关于汽油机油的质量等级分类;CC CD CE CF-4 CG-4 CH-4 CI-4API关于柴油机油质量等级分类。这机个级别的使用性能和质量档次依次升高。

 SC SD SE SF SH SJ EC is the American Petroleum Institute on the classification of gasoline engine oil quality; CC CD CE CF-4 CG-4 CH-4 CI-4 is the API on diesel oil quality grade classification. This machine a level of performance and quality grade in turn increased. 

(3)什么是多级内燃机油,有何优良性能?

  What is the multi-stage engine oil, what good performance?

  多级内燃机油,此种油品粘度范围跨越几个粘度级别,可在一定地区冬夏通用,是一年四季都可使用的油品。如15W/40 10W/30。多级油具有良好的低温启动性能,气温较低时,使发动机顺利启动,防止发动机的磨损,节省燃料。

  Multi-level engine oil, this oil viscosity range across several viscosity levels, can be common in some areas of winter and summer, can be used throughout the year oil. Such as 15W / 40 10W / 30. Multi-grade oil has a good low-temperature start-up performance, low temperature, the engine starts smoothly to prevent engine wear and save fuel. 

4 15W/40W有何含义?

      15W / 40 W What is the meaning?  

   油品在粘度牌号中的WWinter(冬季)的字头,指该油具有良好的低温启动性能,冬夏季皆可使用,属多级油。

  Oil in the viscosity grades of W is Winter (winter) prefix, that the oil has good low temperature start-up performance, can be used in winter and summer, is a multi-grade oil.

(5) 为什么增压柴油机要使用中高档柴油机油?

  Why do supercharged diesel engine to use high-grade diesel engine oil?

  增压柴油机功率大、负荷重、工作温度高,易产生积炭和结焦,中高档柴油机油具有较强的抗高温氧化安全性和良好的清净性,能有效的防止活塞磨损,而普通柴油机难以满足增压柴油机苛刻的工况要求。

 Supercharged diesel engine power, load, high temperature, easy to produce coke and coking, high-grade diesel engine oil has a strong anti-high temperature oxidation safety and good cleanliness, can effectively prevent piston wear, and ordinary diesel engine difficult To meet the harsh working conditions of supercharged diesel engine requirements. 

(6) 车辆齿轮油用在车辆设备的哪些部位?

      Vehicle gear oil in the vehicle equipment, which parts? 

   用于汽车、拖拉机、工程机械车辆等的手动变速箱、差速器、后桥齿轮箱及转向机构上。

 For manual transmissions, differentials, rear axle gearboxes and steering mechanisms for automobiles, tractors, construction machinery vehicles, etc.       

(7) 什么是汽/柴通用内燃机油?

      What is the gasoline / diesel general purpose internal combustion engine oil?  

  通用内燃机油既可用于汽油机,又可用于柴油机,它的开发主要是为了解决汽、柴油车混编车队用油混乱的问题。例如:SF/CC发动机既可用于要求使用SF级汽机油的汽油车,又可用于要求使用CC级柴油机油的柴油车。

    General purpose internal combustion engine oil can be used for gasoline engines, but also for diesel engines, its development is mainly to solve the gasoline, diesel hybrid car fleet confusion problems. For example, the SF / CC engine can be used in petrol vehicles that require SF grade steam oil, or in diesel vehicles that require the use of CC grade diesel oil.  

(8) 何选择合适的粘度等级?

      How to choose the appropriate viscosity grade?

  a 可根据内燃机和车辆的特点,即负荷和转速选油。负荷高,转速低的设备一般选用粘度较大的润滑油。负荷轻、转速高的设备一般选用粘度较小的润滑油;

    A According to the internal combustion engine and vehicle characteristics, namely load and speed of oil. High load, low speed equipment generally use a larger viscosity of the lubricating oil. Load light, high speed equipment generally use a smaller viscosity of the lubricating oil; 

  b 根据气温高低情况选油:气温高时(夏季)选用粘度较大的润滑油;气温低时(冬季)选用粘度较小的润滑油。

   B according to the high and low temperature conditions: high temperature (summer) viscosity greater choice of lubricants; low temperature (winter) use less viscosity of the lubricating oil.  

  c 也可根据发动机磨损状况选择,新发动机应选用粘度小的油品,而磨损较大(间隙增大)的发动机应选用粘度较大的油品。

C can also be selected according to the engine wear conditions, the new engine should use a small viscosity of the oil, and wear a larger (gap increase) of the engine should use larger viscosity of the oil.
