Abstract

The invention relates to the field of engine lubricating oil, particularly to energy-saving diesel engine oil and a preparation method thereof. The energy-saving diesel engine oil is characterized bycomprising the following components in percentage by weight: 60-70% of base oil, 0.1-5% of antifriction additive, 1-10 % of a clearing agent, 2-25% of a dispersing agent, 0.1-5% of an antioxidant and1-20% of a viscosity index improver, wherein the base oil is formed by compounding 95-85% of poly alpha olefin and 5-15% of alkyl naphthalene, and the antifriction additive is a co-doped complex of 50-60% of tungsten disulfide and 40-50% of molybdenum disulfide. According to the invention, the friction force of the engine oil is reduced by improving the components of the diesel engine, so that theoil-saving effect is achieved.

Description

technical field [0001] The invention relates to the field of engine lubricating oil, in particular to an energy-saving diesel engine oil and a preparation method thereof. Background technique [0002] Fuel economy, emission regulations and extended oil change period are the three key factors to promote the development and upgrading of engine oil. Less research has been done on economics. Energy-saving engine oil is also an urgent need for users to reduce costs. According to research, fuel costs account for 50% of the daily operating costs of heavy trucks (excluding initial purchase costs). Using energy-saving engine oil to reduce fuel consumption can effectively improve market competitiveness. Studies have shown that the cost of improving fuel economy by 1% through engine technology upgrades is about $1150, and the cost of improving fuel economy by 1% through powertrain optimization is about $1450, while using energy-saving lubrication Using oil to improve fuel economy by ...
