壳牌早在2011年就启动了针对PC-11标准的产品研发工作,至今壳牌和其合作伙伴已经进行了约9 000项发动机测试,同时对400辆卡车进行了约3 219万km的道路测试。在发动机制造商不断制造出更清洁、更省油柴油机的同时,也对柴油机润滑油提出了更高要求——高清洁度、高耐久性和高燃油经济性。如何使未来的柴油机润滑油满足甚至超越这“三高”要求,目前美国石油协会(API)提出了第11种机油润滑油技术标准——Proposed Category 11(PC-11)。随着标
As early as 2011, Shell started product development for the PC-11 standard. To date, Shell and its partners have conducted about 9,000 engine tests and conducted road testing of about 42.19 million km of 400 trucks. As engine manufacturers continue to create cleaner, more fuel-efficient diesel engines, they also place higher demands on diesel engine lubricants - high cleanliness, durability and fuel economy. How to make the future diesel engine oil meet or exceed this “three high” requirements, the American Petroleum Institute (API) proposed the 11th technical standard of lubricating oil - Proposed Category 11 (PC-11). With the standard
