Problems solved by technology

The use of low-sulfur diesel fuel in diesel fuel can greatly reduce the emission of particulate matter (PM) caused by sulfur elements and aromatic hydrocarbons, and greatly prolong the service life of exhaust gas catalysts. The aggressive substances will be removed along with the sulfur reduction process, which will have varying degrees of influence on diesel lubricating performance, combustion performance, low temperature flow performance and detergency performance

Abstract

The invention provides a low-sulfur diesel oil additive composition. The low-sulfur diesel oil additive composition is composed of a dispersing agent, a diesel oil lubrication improver, a pour point reducer, a cetane number improver and a low-sulfur solvent according to the proportion of parts by weight of 1:0.5-10:0.5-50:0.5-100:0.5-200. The low-sulfur diesel oil additive composition provided by the invention is used as an additive for the low-sulfur diesel oil, introduces no new sulfur element, can meet the environment protection rules, not only can avoid harm to vehicles caused by the new sulfur element introduced in the normal low-sulfur diesel oil additive, but also can obviously improve the lubricating property of the diesel oil, reduce attrition of a fuel injection system and prolong the service life of an engine, can improve the cetane number of the diesel oil, can enhance the combustion performance of the diesel oil, can reduce discharge of the pollutants, such as coking materials, particles, incomplete combustion discharge and CO, reduce carbon deposition of the engine, prolong the service life of the engine and improve the thermal efficiency of the engine, and also can lower the oil consumption.

Description

technical field [0001] The invention relates to the technical field of energy combustion, in particular to a low-sulfur diesel oil additive composition and a preparation method thereof. Background technique [0002] As a product of petroleum refining, diesel oil occupies a relatively high share in the fuel structure of various countries. In addition, diesel engines for automobiles are more fuel-efficient than gasoline engines (about 30v%), and the CO and HC emissions of diesel engines are lower than those of gasoline engines with the same performance. 2 It is also less than gasoline engines, which is conducive to energy saving and environmental protection. Therefore, the trend of diesel vehicles at home and abroad is accelerating, and the demand for diesel will increase in the future. [0003] Sulfur content is an important indicator of the properties of vehicle diesel, which is used to characterize the corrosion performance of vehicle diesel and its influence on exhaust co...
