Problems solved by technology

Since the end of the 1990s, a variety of fuel additives have been introduced at home and abroad, all of which have certain limitations in practical application. Most of them only have a cleaning effect on the carbon deposits in some parts of the engine, or are flammable and explosive products, which are not suitable for long-distance transportation

Abstract

The invention relates to an automobile fuel oil system cleaning additive. The automobile fuel oil system cleaning additive is finally prepared by using high-activity polyisobutene amine, polyetheramine, monoisobutylene succinylimine, 2,6-tert-butyl-4-methylphenol, isooctyl stearate and N,N-dimethyl formamide as raw materials according to a proper weight proportion; the finally prepared automobilefuel oil system cleaning additive and gasoline are added according to a certain proportion; the automobile fuel oil system cleaning additive can fast permeate inside deposited carbon of an engine andbetween the deposited carbon and a substrate; the deposited carbon is peeled from the substrate, so that the goal of clearing the deposited carbon is achieved; the cleaning effect is high; the effecttaking is fast. The automobile fuel oil system cleaning additive has the advantages that the deposited carbon of an engine fuel oil system, an air inlet system and a combustion system can be effectively cleared; the automobile fuel oil system cleaning additive is suitable for electronic injection and direct injection engines; the automobile fuel oil system cleaning additive does not contain inflammable and explosive ingredients, so that the storage and the transportation are convenient.

Description

technical field [0001] The invention belongs to the technical field of fuel cleaners, and in particular relates to an automotive fuel system cleaning additive and a preparation method thereof. Background technique [0002] Carbon deposits are the residues deposited in the combustion chamber after the fuel is burned. It is formed by the accumulation of small molecules. It can also be said that it is the deposit produced by the incomplete combustion of the mixture of fuel and lubricating oil. The carbon deposits in the engine block can be clearly seen through the endoscope used for automobile inspection. As the number of kilometers traveled by the car increases, more and more carbon deposits will accumulate. Too much carbon deposits will cause cold start difficulties, and the vehicle will vibrate when idling. Carbon deposits are very harmful to the engine. Unstable idling speed, engine overheating, increased fuel consumption, decreased power, increased exhaust emissions, and ...
