DIESEL ENGINE OIL COMPOSITION FOR IMPROVING FUEL EFFICIENCY AND ENDURANCE PERFORMANCE |
摘要 |
Disclosed is a novel diesel engine oil composition for fuel efficiency and endurance performance. The diesel engine oil composition may maximize frictional resistance and wear resistance by facilitating the formation of a lubricating film on a metal surface, extend an oil change cycle with excellent engine protection ability, and improve fuel efficiency due to friction reduction. The diesel engine oil composition include: base oil; a calcium-based or magnesium-based sulfonate detergent dispersant; a viscosity index improver selected from the group consisting of a diene copolymer, a polystyrene-diene copolymer and a hydrogenated polystyrene-diene copolymer; and a low friction agent including molybdenum dithiocarbamate (MoDTC) and glycerol monooleate (GMO). |

1. A diesel engine oil composition, consisting of:
a base oil in an amount of about 75 to 85% by weight based on the total weight of the diesel engine oil composition; one or more of detergent dispersants selected from the group consisting of calcium sulfonate and magnesium sulfonate in an amount of about 5 to 20% by weight based on the total weight of the diesel engine oil composition; one or more of viscosity index improvers selected from the group consisting of a diene copolymer, a polystyrene-diene copolymer and a hydrogenated polystyrene-diene copolymer in an amount of about 1 to 10% by weight based on the total weight of the diesel engine oil composition; and a low friction agent including molybdenum dithiocarbamate (MoDTC) and glycerol monooleate (GMO) in an amount of about 0.5 to 2% by weight based on the total weight of the diesel engine oil composition. |
