Problems solved by technology

[0003] A large number of long-term studies have shown that fuels such as gasoline or diesel are burned in a very short moment in the engine combustion chamber, that is, they are discharged, such fuels are not completely burned, and the remaining fuel is burned as intermediate products of combustion or even unburned. This will not only reduce the efficiency of fuel use, but also cause a large amount of harmful gases, such as hydrocarbons and intermediate products of incomplete combustion of fuel oil, to be discharged into the air and pollute the atmosphere
Therefore, the quality problems of the existing fuel itself and the shortage of locomotive engine manufacturing limits make the existing fuel not only low in combustion efficiency, but also unable to protect the engine and prolong the service life of the engine.

Abstract

The invention discloses a fuel oil additive. The fuel oil additive is composed of the following raw materials, by weight, 6-12 parts of polyisobutene amine, 5-10 parts of urotropine, 20-40 parts of lauric isopropanolamide, 5-15 parts of cosolvent, 0.5-1.0 part of sucrose acetate iso-butyrate, 0.8-1.0 part of glycol distearate and 10-25 parts of combustion improver. The invention also discloses a preparation method for the fuel oil additive. The fuel oil additive has functions of raising the combustion efficiency, cleaning carbon, removing dirt, saving energy and reducing emission.

Description

technical field [0001] The invention relates to a fuel additive, in particular to an energy-saving and emission-reducing fuel additive and a preparation method thereof. Background technique [0002] Oil resources are tight and energy is in short supply. How to solve the energy shortage has become a research topic that countries all over the world pay attention to. As an important fuel, fuel oil has become the main power fuel for large equipment due to its advantages of high power and low price. Fuel, such as gasoline or diesel, needs to introduce an oxidant (usually oxygen in the air) when burning in the combustion chamber of an internal combustion engine. The expansion caused by the high-temperature and high-pressure gas produced after combustion directly generates driving force, driving the moving parts of the engine such as the piston , making it move to generate effective mechanical energy. Modern cars all use internal combustion engines. Volatile gasoline or diesel is...
