Description

technical field [0001] The invention relates to the field of chemical industry, and relates to a diesel engine oil, in particular to an environment-friendly energy-saving diesel engine oil and a preparation method thereof. Background technique [0002] Diesel engine oil refers to a type of vehicle lubricating oil used in diesel engines of trucks, trucks and buses to lubricate, reduce friction, clean, cool, seal, and prevent rust and corrosion. Diesel engines are generally used as the power of trucks and trucks, and their operating conditions range from on-off city driving to high-speed driving on highways between cities. Therefore, the engine oil should not only have good high-temperature oxidation stability and wear resistance , should also have excellent ability to inhibit and disperse low-temperature sludge; in addition, due to the wide operating range of diesel engine oil, for example, the temperature in cold regions can reach -40°C or even lower, and if the viscosity is...
