如何选择适合的润滑油?
发布者: 发布时间:2016-05-26 浏览量:

 首先,应考虑选择何种粘度的润滑了。

First of all, should consider the choice of the viscosity of the lubrication.

选择润滑油的粘度要依据发动机的工作环境条件,通常主要考虑:

Select the viscosity of the lubricating oil to work under the conditions of the engine, usually the main consideration:

1、温度:常处高温条件,应该选高粘度;常处低温条件,应该选低粘度。

   temperature: often high temperature conditions, high viscosity should be selected; often low temperature conditions, should choose a low viscosity.

2、负荷:工作负荷大,应该用高粘度的。润滑油添加剂领域的科技进步,使润滑油的粘度-温度特性有了很大的改善,产生了一种复式粘度的润滑油如埃尔曼全合成汽机油SN 5w40采用独特的三层油膜磁性纳米技术,它在低温零下30℃时流动性能仍非常好,在高温时粘度不会降低太多,保证足够的油膜强度。

      load: work load, should be high viscosity. Lubricant additives in the field of scientific and technological progress, so that the viscosity of oil viscosity - temperature characteristics have been greatly improved, resulting in a double viscosity of the lubricants such as Elman Synthetic Motor Oil SN 5w40 using a unique three-layer film magnetic nano Technology, its low temperature at minus 30 when the flow performance is still very good at high temperatures will not reduce too much viscosity, to ensure adequate film strength.

其次,还应考虑选择何种等级的润滑油。

Second, we should also consider the choice of what grade of lubricating oil.

目前,西方发运国家,SE SF级的润滑油基本上已经停止生产和使用,而国内由于多种原因,有些地区低级别的润滑油仍然大行其道。这其实是我们的汽车寿命短,维修费用高的一个重要原因。所以我们在推荐润滑油的级别时,比目前国内润滑油的使用习惯一个等级,这样做的目的,是希望广大的司机朋友能够正确使用润滑油,从而养护好您的爱车,提高汽车的使用寿命,节省维修费用。现在,我们选取机种有代表性的汽车来说明选择润滑油的等级的方法:微型面包车一般可选SE级;夏利可选SF级及级上;桑塔纳可选SG级及以上;本田可选SH级及以上;福特应选世界顶级SJ级。

At present, the Western shipping country, SE SF-class lubricants basically have ceased production and use, and domestic for a variety of reasons, some areas of low-level lubricants are still popular. This is actually our car life is short, an important reason for high maintenance costs. So we recommend the level of lubricants, than the current domestic use of lubricating oil a grade, the purpose of doing so, I hope the majority of the driver friends to use the correct oil, so conservation of your car, improve car use Life, save maintenance costs. Now, we select the representative models of vehicles to choose the method of selecting the level of lubricants: mini-van general optional SE level; Xiali optional SF level and level; Santana optional SG level and above; Honda optional SH Class and above; Ford should choose the world's top SJ level.

但是,有以下情况的汽车应提高一至二个等级:

However, the following circumstances should increase the car one or two grades:

   1 在城市中行驶,由于经常堵车,走走停停,发动机工作温度不稳定,容易积碳,加快磨损(发动机的磨损70%发生在起动阶段);

 driving in the city, due to frequent traffic jams, stop and go, the engine operating temperature instability, easy to carbon deposition, accelerated wear and tear (70% of the engine wear occurs in the starting phase);

2 长途高速行驶,发动机长时间处于高温状态;

long-distance high-speed driving, the engine at a high temperature for a long time;

3 急速行驶,发动机转速要求快拉高,切换档频率又快,机件所受阻力变化争剧;

rapid driving, the engine speed requirements quickly pulled high, the frequency of fast switching gear, mechanical resistance to changes in drama;

4 高负荷行驶如轿车装货,货车超载,这时发动机要吸入更多的油气才能运转,行车速度慢,散热又不好,一般机油会导致很快劣化变质失效。

    high-load driving such as car loading, truck overload, then the engine to inhaled more oil and gas to run, driving speed is slow, heat and bad, the general oil will lead to deterioration soon deterioration.
