Description

Gasoline detergent composition
Technical Field
The invention belongs to the technical field of gasoline additives, and particularly relates to a gasoline detergent composition.
Background
With the increasing concern of the environmental pollution and the energy consumption problem all over the world, the continuous progress of the automobile technology is promoted, and the application of various new technologies to automobiles also puts higher requirements on the quality of the automobile gasoline, and especially puts strict requirements on the cleanliness of the automobile fuel. Gasoline vehicles currently in use mostly use engines with electronically controlled direct fuel injection technology. The complex chemical reaction of hydrocarbon which is not completely burnt out by gasoline can cause the generation of sediment, carbon deposit and the like in a combustion chamber, further the carbon deposit and coke are generated in an engine, the working condition of the engine is seriously influenced, and the power is reduced, the emission of tail gas pollutants is increased and the oil consumption is increased. Research shows that the olefin (especially the conjugated olefin) is easy to cause the generation amount of the deposit of the fuel nozzle to increase and has certain influence on the generation of the deposit of the combustion chamber; while the aromatic hydrocarbon has a more significant effect on the deposits at the intake valve, the combustion chamber, etc., the increase in the content of the aromatic hydrocarbon (particularly the high boiling components therein) tends to cause an increase in intake valve deposits and combustion chamber deposits. Based on the above, gasoline detergents are available in the market and are added into fuel oil, so that the power performance can be improved to a certain extent and the emission period pollutants can be reduced.
For example, in chinese patent CN200410069126, a gasoline detergent composition is introduced. The components of the composition comprise: a polyisobutylene amine; more than one polyether with alkylphenol and/or dihydroxy and more than two polyoxyethylene ethers; the composition can effectively remove oil sludge and gel deposit formed by a fuel system of a spark ignition type automobile engine, and can inhibit the generation of gel deposit at the parts. In Chinese patent CN200710152389.1, a gasoline detergent capable of reducing the deposit in the combustion chamber of a gasoline engine is introduced, the gasoline detergent comprises polyisobutylene amine with high surface activity, polyether carrier liquid with excellent oil solubility, cosolvent, antioxidant, antirust agent, preservative and demulsifier, and the detergent is added into the commercially available vehicle gasoline according to the dosage of 400-600 ppm, so that the gasoline detergent can inhibit and clean the oil nozzle and the air inlet valve of the fuel intake system of the automobile engine, and can obviously reduce the deposit in the combustion chamber of the gasoline engine.
The gasoline detergents on the market at present can have the advantages of improving the fuel combustion efficiency, eliminating or inhibiting the generation of sediments, reducing the emission of harmful substances and the like, but still have the defects that when the gasoline detergents are added into gasoline for use, the diameter of the wear-scar of the mixed gasoline is increased under the reciprocating work of an engine, namely the abrasion resistance and the lubricity of the mixed gasoline are deteriorated.
