Marine System Oil
DCC3008, 4008
Product Introduction
PetroChina Lubricant Company’s DCC3008 and DCC4008 Marine System 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. Its formulation has good detergency with great dispersant capability, anti-corrosion, and oxidation stability proven by the bench test. Its quality meets the international standard and requirement.
Applications
Kunlun Marine DCC3008 、 DCC4008 System Oil is for use in low speed crosshead engine, burning heavy fuel oil. It is an ideal lubricating oil for new generation of high efficiency crosshead marine diesel engine with cylindrical piston that combusts low sulphur content fuel with sulphur content less than 0.5%.
Features
? Excellent heat stability that cools piston and crank axle/shaft and is resistant to microbiological degradation resulting in longer oil life
? Effective sludge separation capability
? Excellent anti-oxidation and anti-corrosion that reduces oxidation and abrasion within the crankcase effectively
? Excellent anti-wear that provides effective and efficient lubrication at high temperature and high pressure environment
? Excellent water resistance and separation capability for easy removal of contaminated water by centrifuge
Field Test and Result
? Approval from MAN B&W.
? Cylinder and piston operate with no sign of abrasion and there is no deposit formation in the piston ring or piston. Less ash was observed at the exhaust and has good water shedding properties.
? No formation of submerge particles, floating particles and insolubility and etc problems were experienced when mixing DCC3008 and DCC4008 with any other types of similar marine system oil.
