摘要
国Ⅳ排放法规的实施促使柴油发动机制造厂商改进发动机设计,增加后处理装置以适应环保的要求。柴油发动机的变化对润滑油产生了极大的影响,要求发动机油具有低硫盐灰分、低硫、磷元素,对产品配方及单剂提出了新的挑战。各OEM厂采用后处理技术各异,对发动机油要求也不尽相同,研制满足各发动机厂商国Ⅳ排放专用油是目前发动机油研发的一个重要方向。
The implementation of China Ⅳ emission legislation induces the diesel engine promotion and after-treatment systems development from engine manufacturers to meet enforced legal requirements.Changes of the diesel engine bring higher standards for lubricants.Low SAPS(lower levels of Sulphated Ash,Phosphorus and Sulphur) engine oils are required,and that will bring a challenging issue to develop high quality lubricant formula and additives.The demand of engine oils varies with OEMs technologies,so it is an impo...
