Application Research on Long-Life Light-duty Diesel Engine Oil
Energy conservation and environmental protection have become the main driving forces for the development of the automotive industry.The requirements of small size,high power density,and extended oil change intervals(15,000 to 30,000 kilometers)pose significant challenges to lubricating oils in light-duty diesel engines.The research has independ-ently developed a 5W-30 C3+long-life light-duty diesel engine oil on the ACEA light-duty diesel engine oil technology platform and plans to conduct two 30,000-kilometer oil change interval road tests on China VI light-duty diesel vehicles.The test data shows that Kunlun's independent products can maintain good viscosity stability after fuel dilution,resist oxida-tion deterioration after long-distance oil change intervals,possess stable alkaline retention,and exhibit excellent anti-wear properties with low levels of wear metals.It meets the technical requirements of a 30,000-kilometer oil change inter-val,thereby saving maintenance costs for vehicle owners.
