随着柴油机单缸功率的提高和油耗的降低,柴油机的腐蚀磨损情况也加重了。为了防止柴油机损坏,不少大型的柴油机厂宁可采用含有无灰分散剂和高碱度的润滑油。阿摩可化学公司现已研制出一种新型的添加剂,以配制高碱度(10TBN‘总碱性值’)的润滑油。这种润滑油可以满足现代船舶和机车用的柴油机以及其他固定式高负荷柴油机的最苛刻的要求。最近在美国通用电气公司和美国通用电机公司生产的柴油机上所进行的现场试验,证明了这种新型的阿摩可6555型柴油机润滑油添加剂具有如下的特点:
With the increase of single-cylinder diesel engine power and fuel consumption, diesel engine wear and tear also increased. In order to prevent diesel engine damage, many large-scale diesel engine plants prefer to use lubricants containing ash-free dispersants and high alkalinity. Amoco Chemical has now developed a new type of additive to formulate a high alkalinity (10 TBN ’Total Alkalinity’) lubricant. This lubricant meets the most demanding requirements of modern marine and locomotive diesel engines and other stationary, high-load diesel engines. Field tests conducted recently on diesel engines manufactured by General Electric Company of the United States and General Electric Company of the United States have proved that the new Amoco 6555 diesel engine lubricant additive has the following characteristics:
