The grade of protection of an engine oil is determined by its resistance to wear, oxidation and many other oil properties. Wolf proves that its lubricants have the right protective properties by checking the composition of the fluid.
1.发动机保护证明
发动机油的保护等级取决于其耐磨性、抗氧化性和许多其他油性。通过对其车用液成分的检测，证明了Wolf润滑油具有正确的保护性能。FTIR
An infrared spectroscopy shows the well-hidden components inside freshly arrived additive packages and finished products. This test allows us to open a window and look at a fluid at a molecular level. Different wavelengths of light are sent through a cell holding the oil sample, after which the machine measures the absorption rate of the sample for each beam of light. Each type of component absorbs light at different wavelengths, giving us a clear view of the components present within the sample. Each batch of finished WOLF OFFICIALTECH 0W20 LL FE leaving our factory has proven that it contains the desired protective additives.
FTIR
红外光谱显示最新到货的添加剂包和成品中含有良好的隐形成分。该测试允许我们打开窗口并从分子状态对车用液进行观察。不同波长的光通过油样细胞发送之后，机器对每个光束的样品吸收率进行测试。每种类型的成分在不同波长的吸收率让我们对样品成分有了清晰的了解。出厂的各批次WOLF OFFICIALTECH 0W20 LL FE成品已经证明它含有所需的保护性添加剂。Our network of reliable suppliers is a secondary proof of quality and protection. They deliver only the highest-quality additives that contain exactly the right protective properties. Wolf’s longstanding relationships with renowned additive suppliers do not replace our rigorous testing procedures; we always put the delivered raw materials through our stringent testing procedures.
我们可靠的供应商网络是质量和保护性能的旁证。他们只供应含有最佳保护性能的最高品质的添加剂。Wolf与知名添加剂供应商的长期合作关系并未取代我们严格的测试程序；我们始终对交付的原材料采取严格的测试程序。 - Proof of increased fuel economy
Everyone is looking for more efficient ways to move, making fuel economy one of the most sought-after engine properties. Without the right engine oil, it is impossible for the latest vehicles to reach the desired level of fuel economy. Let us show you how it works:
2.燃油经济性提高的证明
人人都在寻求更加高效的出行方式，这使得燃油经济性成为了最受追捧的发动机属性之一。没有合适的发动机油，最新的车辆不可能达到所需的燃油经济性水平。工作原理：
Friction reducing properties
Friction absorbs energy thus lowers the efficiency of the engine. Friction reducing additives and extreme-pressure additives, which are mainly used within high-pressure applications like transmission systems or differentials, reduce friction by reinforcing the oil film. We prove the presence of friction reducing additives within our products with the FTIR method, which we also use to prove the engine oil’s protective properties.
减少摩擦性能
摩擦吸收能量导致发动机效率降低。主要使用于传输系统或差速器等高压应用的减摩添加剂和极压添加剂通过增强油膜来减少摩擦。我们使用FTIR方法证明了我们产品中存在减摩添加剂，也以此证明发动机油的保护性能。
Low viscosity
The fluid within the engines also causes friction itself. Viscosity is “the resistance of a fluid to flowing” meaning that a viscous fluid will cause the engine to consume more fuel. The lower the viscosity the better? Well, it comes with a limit. A too low viscosity fluid won’t form a stable oil film. The bottom limit of the viscosity is determined with a High Temperature High Shear test (HTHS test). This test simulates real operational conditions by exposing the oil to high temperatures and fast moving components.
低粘度
发动机内的车用液也会引起摩擦。粘度是“车用液对流动的阻力”，意味着粘性车用液将导致发动机消耗更多燃料。粘度越低越好？是这样，但也有限度。粘度太低的车用液不会形成稳定的油膜。用高温高剪切测定仪试验（HTHS试验）测定粘度的下限。该测试通过将发动机油暴露在高温和快速移动的部件中来模拟真实的操作条件。
At our lab, we use two other tests to check for the additional viscosity properties of our engine oil sample:
在我们的实验室，我们使用另外两个测试来检查我们的发动机油样的额外粘度特性：
Dynamic viscosity test
Fast-moving engine parts are exposed to friction from other parts and from the lubricant itself! This directly influences the fuel consumption, so it is crucial to balance this resistance with the oil’s protective properties. Winter viscosity, in the case of our sample this is the ‘0’ in front of the ‘W’, is determined with a Cold Cranking test at temperatures as low as -35°C. Our lab technicians conduct this test by adding a rotating element to a fluid, after which they measure the amount of force needed to stir the sample at low temperatures.
动态粘度测定
快速移动的发动机部件会受到其他部件和润滑油本身的摩擦！这将直接影响油耗，因此平衡这种阻力与油的保护性能至关重要。我们采用0-W标号机油在低至-35°C的温度下通过冷启动进行冬季粘度确定测试。
我们的实验室技术人员在该测试中在车用液中添加了旋转元件，然后测量在低温下搅拌样品所需的力度大小。
Kinematic viscosity
We check the second SAE viscosity to define the ‘20’ in ‘0W20’. The test set-up measures the time it takes for a set volume of engine oil to run through a glass tube under the influence of gravity. The quicker it flows, the lower the viscosity. We measure the SAE kinematic viscosity at 100°C to mimic the operational conditions found within a running engine.
运动粘度
我们对SAE（国际自动机工程师学会）粘度进行了再次检测以对“0W20”机油中的“20”进行了定义。测试装置测量一定体积的发动机油在重力影响下穿过玻璃管所需的时间。流动越快，粘度越低。我们对100°C时的SAE运动粘度进行了测定，以模拟运转中的发动机的运行情况。
3. Proof of resistance against low temperatures
The base oils and pour point depressants of the engine oil determine the pour point of engine oil. WOLF OFFICIALTECH 0W20 LL FE has an excellent low pour point of -51°C, but how do we test for this property?
3.抗低温证明
发动机油的基础油和倾点下降剂决定了发动机油的倾点。WOLF OFFICIALTECH 0W20 LL FE具有-51°C的极佳低倾点，但我们如何测试该属性？
Pour point: “The lowest temperature at which a liquid remains fluid.”
倾点：“车用液保持流动的最低温度。”
The most efficient way to determine the pour point of a fluid is to lower its temperature and try to pour it! ASTM D6892, also known as the Robotic Tilt Method, is an automatic machine that tests for the pour point of fluids. A tube containing a sample of the oil is put into the machine. The machine lowers the temperature of the sample at a pre-set rate, and every 3°C it tips the tube. An extremely accurate optical device checks whether the oil is still flowing. The machine automatically repeats this process until the fluid stops flowing.
确定车用液倾点的最有效方法是降低其温度并尝试倒出！也称为机器人倾斜法的ASTM D6892是一种测试车用液倾点的自动机器。将装着样油的管子放进机器中。机器按照预设降低样油温度并每隔3°C就会倾斜一次管子。一个极其精确的光学设备检查油是否仍在流动。车用液停止流动之前机器会自动重复该步骤。
Our sample of WOLF OFFICIALTECH 0W20 LL FE showed no sign of flowing at -54°C. Afterwards we added 3°C, which is the temperature interval of this standardised test, to obtain the outstanding -51°C test result!
我们的WOLF OFFICIALTECH 0W20 LL FE样油在-54°C时 无流动迹象。然后我们添加了该标准化测试的温度间隔3°C，以获得出色的-51°C测试结果！
