The invention discloses environment-friendly and energy-saving diesel engine oil. The environment-friendly and energy-saving diesel engine oil consists of 85-90% of base oil and 10-15% of other additives. According to the invention, by compounding poly-alpha olefin (PAO) and dioctyl sebacate as the base oil, various functional additives are selected and predicted through an artificial neural network algorithm and an optimal formula is selected through a genetic algorithm so as to acquire diesel engine oil components with different specifications and cost performances. The diesel engine oil disclosed by the invention has the advantages of low viscosity, good cryogenic property, good viscosity-temperature property, low volatility, low traction coefficient, energy conservation, high viscosity index, good shear retardant property, good lubrication cooling performance, good thermal oxidation stability, good control performance to high-temperature sediments, good detergency, high-temperature foam resistance, corrosion resistance, abrasion resistance and good degradability; and meanwhile, the power of a diesel engine is increased, the reliability and the fuel economy are improved, and the oil draining period and the service life of the diesel engine are effectively prolonged. |
