Abstract

The invention discloses a diesel oil additive and a preparation method thereof. The diesel oil additive includes a multifunctional agent and aviation kerosene with a mass ratio of 1:1-5, in parts by mass, wherein the multifunctional agent includes the following components : 60-100 parts of 2-ethylhexyl nitrate, 1-20 parts of light solvent naphtha, 1-20 parts of heavy solvent naphtha, 0.1-10 parts of 1,2,4-trimethylbenzene, 1, 0.1-10 parts of 3,5-trimethylbenzene, 0.05-8 parts of naphthalene, 0.05-8 parts of n-propylbenzene, and 0.05-5 parts of cumene. The diesel additive of the present invention can clean the carbon deposits in the fuel injector, make the combustion more complete, improve the fuel utilization efficiency, increase the power, restore the good atomization effect of the fuel, improve the difficult condition of cold start, and can effectively improve the stability of diesel oil. Fully compatible.

Description

technical field [0001] The invention belongs to the technical field of fuel oil additives, and in particular relates to a diesel oil additive and a preparation method thereof. Background technique [0002] Compared with gasoline, the content of unsaturated hydrocarbon impurities in diesel is higher, which makes it difficult for diesel to burn completely. Therefore, diesel engines are prone to black smoke and carbon deposits, which are more likely to form carbon deposits at the engine nozzle, which affects The engine works normally, resulting in increased fuel consumption, worsened exhaust emissions, and shortened engine life. Diesel is one of the non-renewable energy sources. With the reduction of natural oil storage, improving the cleanliness of diesel and making diesel fully combustible is a matter of great concern in the chemical industry and the automobile industry. Especially in the diesel currently used in my country, catalytic cracking The proportion of diesel oil is ...
