Marine Cylinder Oil
DCA5070H
Product Introduction
PetroChina Lubricant Company’s DCA5070H Marine Cylinder Oil is produced from the deep refined base oil from XinJiang’s crude which undergoes precise
de-waxing process and a unique blending process by using our special overbased naphthenate as main additive and other additives such as anti-oxidation and etc. With its enhanced formulation, DCA5070H and has a better detergency with good dispersant capability, anti-corrosion, and oxidation stability is proven by the bench test. Its quality meets the international standard and requirement.
Applications
KunLun Marine DCA5070H Cylinder Oil is for use in low speed crosshead engine, burning heavy fuel oil with sulphur content less than 3.5%. It is an ideal lubricating oil for new generation of high efficiency, low speed crosshead marine diesel engine with long strokes.
Features
? Excellent detergency that cleans and maintains cylinder and piston
? Excellent oxidation stability at high temperature that prevents formation of unwanted oxides at high temperature
? Excellent anti-oxidation, anti-corrosion and good alkalinity that can reduce corrosion and damage of cylinder and piston from combusting of high sulphur content fuel
? Excellent dispersant capability to provide effective and efficient lubrication
? Excellent anti-wear property that reduces linear and ring wear under both high temperature and high pressure environment
Field Test and Result
? Approval from MAN B&W
? No formation of submerge particles, floating particles and insolubility and etc problems were experienced when mixing DCA5070H with any other types of similar marine cylinder oil
