在过去的40年里,伴随着重载卡客车制造业技术水平的不断提升和柴油发动机的换代升级,柴油发动机润滑油也不断发展进化,目前最高的美国石油协会(API)标准已经达到CJ-4。经过反复的实验,壳牌坚信在不牺牲润滑油保护性能的同时,新一代的低黏度润滑油完全可以把发动机的燃油经济性能发挥到最大。在发动机制造商不断制造出更清洁更省油的柴油发动机的同时,也提出了对未来柴油发动机润滑油的更高要求:高清洁度、高耐久性和高燃
In the past 40 years, with the continuous improvement of the technical level of heavy-duty truck manufacturing industry and the upgrading and upgrading of diesel engines, the development of diesel engine lubricants has continued to evolve. At present, the highest American Petroleum Institute (API) standard has reached CJ- 4. After repeated experiments, Shell firmly believe that without sacrificing the protective properties of lubricants at the same time, a new generation of low viscosity lubricants can fully engine fuel economy to maximize performance. As engine manufacturers continue to create cleaner and more fuel-efficient diesel engines, higher demands on future diesel engine oils have also been raised: high cleanliness, high durability and high combustion
