Abstract

The cleaning agent for fuel oil system includes: 5-20% of macromolecular cleaning dispersing agent which can be one of polyisobutyramide, polyether amine, polyalkylphenol, alkylpolyuerthane and polyisobutylene succimide, 10-30% of breakout oil which can be one of alkylpolypropylene glycol ether, alkalpolybutaglycol ether, engine oil, base oil, liquid paraffin and vegetable oil, 5-20% of water-removing agent which can be one or two kinds of main group phenol polyethenoxy ether, octadecyl polyethenoxy ether, Peregral, dodecyl alcohol amide, Tween-80 and Span-80, 15-35% of polar solvent which can be one or several kinds of isopropanol, isobutanol, ethylene glycol monomethyl ether and ethylene glycol monobutyl ether and 30-65% of diluting agent.

Description

(1) Technical field [0001] The invention belongs to a gasoline vehicle fuel system cleaning agent. (two), background technology [0002] Impurities in gasoline, external moisture, and oxidation products of gasoline olefins will gradually deposit in fuel tanks, oil pipes, carburetors, etc. Colloids are deposited in the carburetor, intake manifold, intake valve, and combustion chamber, and further oxidized into carbon deposits. These deposits will cause the mixed gas to deviate from the ideal value, accelerate the corrosion of metal parts, poor air intake, and combustion Defects such as reduced heat conduction parts in the chamber, increased compression ratio, early combustion, increased fuel consumption, increased exhaust gas, and decreased power. Therefore, people use different methods to clean the deposits in the fuel system. The conventional method is to manually scrub the car or soak it in strong alkali solution, which will cause metal corrosion and damage the inherent ...
