Embodiment 1

[0019] Take 9 parts of polyisobutylene amine, 6 parts of tetrahydrofurfuryl nitrate, and 5 parts of polyetheramine into a closed mixing tank, and mix well, then add 3 parts of polyisobutylene isobutyl carbamate, polyisobutadiene 0.5 parts of ethylenediamine, 8 parts of ethylene glycol dimethyl ether, stir for 10-15 minutes and mix well, then add 4 parts of 4,4'-dihexyldiphenylamine, 4-hexyl-4'-octyl 1 part of diphenylamine, stirred for 15-20 minutes to mix uniformly to obtain the lubricating gasoline detergent and dispersant of the present invention.

Embodiment 2

[0021] Take 9 parts of polyisobutylene amine, 9 parts of tetrahydrofurfuryl nitrate, and 5 parts of polyetheramine and add them into a closed mixing tank. After mixing well, add 5 parts of polyisobutylene isobutyl carbamate, polyisobutadiene 0.5 parts of ethylenediamine, 5 parts of ethylene glycol dimethyl ether, stir for 10-15 minutes and mix well, then add 4 parts of 4,4'-dihexyldiphenylamine, 4-hexyl-4'-octyl 3 parts of diphenylamine, stirred for 15-20 minutes to mix uniformly to obtain the lubricating gasoline detergent and dispersant of the present invention.

Embodiment 3

[0023] Take 12 parts of polyisobutylene amine, 6 parts of tetrahydrofurfuryl nitrate, and 3 parts of polyether amine and add them into a closed mixing tank. After mixing well, add 5 parts of polyisobutylene carbamate, polyisobutadiene 0.5 parts of ethylenediamine, 5 parts of ethylene glycol dimethyl ether, stir for 10-15 minutes and mix well, then add 4 parts of 4,4'-dihexyldiphenylamine, 4-hexyl-4'-octyl 3 parts of diphenylamine, stirred for 15-20 minutes to mix uniformly to obtain the lubricating gasoline detergent and dispersant of the present invention.

Abstract

The invention belongs to the field of gasoline additives, and particularly relates to a lubricating gasoline detergent dispersant. The lubricating gasoline detergent dispersant is composed of polyisobutylene amine, tetrahydrofurfuryl nitrate, polyetheramine, polyisobutylene isobutyl carbamate, polyisobutyl diene ethylidene diamine, glycol dimethyl ether, 4,4'-dihexyldiphenylamine and 4-hexyl-4'-octyl diphenylamine according to the specific proportion. The polyisobutylene amine, tetrahydrofurfuryl nitrate, polyetheramine, 4,4'-dihexyldiphenylamine and 4-hexyl-4'-octyl diphenylamine can be synergically combined to prevent and remove the carbon deposit in the oil injection nozzle of the direct-injection engine, thereby achieving the effect of removing the carbon deposit in the oil injection nozzle. The polyisobutyl diene ethylidene diamine and polyisobutylene isobutyl carbamate have the effects of purging and dispersion, and can prevent the carbon deposit in the engine intake system and combustion chamber due to the multicomponent addition.

Description

technical field [0001] The invention belongs to the field of gasoline additives, in particular to a lubricating gasoline detergent and dispersant. Background technique [0002] The direct-injection gasoline engine adopts the oil supply technology similar to that of the diesel engine, and provides the required pressure of more than 100 bar through a piston pump, and supplies gasoline to the electromagnetic injector located in the cylinder. Then the fuel is directly injected into the combustion chamber at the most appropriate time through the computer-controlled injector. Through the design of the internal shape of the combustion chamber, the mixture can generate a strong vortex to fully mix the air and gasoline. Then the area around the spark plug can have a richer mixture, and the other surrounding areas have a leaner mixture, ensuring that the lean combustion can be achieved as much as possible under the condition of smooth ignition. However, due to problems such as direct...
