Problems solved by technology

[0006] (3) The oil solubility of fuel detergent is poor, resulting in low solubility of organic salts in fuel
When there are organic salts in the additive, not only is it easy to wear the cylinder during combustion, but also gelatinous matter and carbon deposits will appear after combustion, which will easily block the oil passage and reduce the fuel saving rate, thus affecting the promotion of detergents.
[0007] (5) At present, the role of additives in fuel detergents is relatively single, resulting in an overly complex formula, which will lead to antagonism between some additives

Embodiment 1

[0050] 1.1 Production of sample

[0051](1) Material selection instructions: choose water as the dirt wetting agent and the initiator of gasoline "secondary atomization". Triethanolamine is used as a dirt dispersant and corrosion inhibitor on metal surfaces, as a hydrogen sulfide absorbent and as an anti-corrosion agent for oil products to prevent oil products from stink. N-butanol is a gasoline modifier to improve its anti-knock performance and because it is in the middle of hydrophilic and lipophilic solvents, it acts as a phase solvent. Detergent (6501), nonylphenol polyoxyethylene (4) ether, and nonylphenol polyoxyethylene (8) ether are surfactants, which are used for wetting, penetrating, solubilizing, dispersing, cleaning, corrosion inhibition, and reducing The surface tension and synergistic properties of fuel oil improve carbon removal efficiency. Ethylenediamine is a carbon removal agent and an acid gas absorbent in gasoline. Ethylene glycol monobutyl ether is a solu...

[0079] 2.1 Production of sample

[0080] (1) Description of material selection:

[0081] 1) For the functions and efficacy of water, triethanolamine, n-butanol, ethylene glycol monobutyl ether, nonylphenol polyoxyethylene (4) ether, nonylphenol polyoxyethylene (8) ether, and detergent 6501, see "Implementation Example 1 Recipe" instructions.

[0082] 2) Methanol is selected as a material to utilize the characteristics of complete combustion of methanol and a higher volume increase ratio than gasoline, so that the internal combustion engine has a wide range of ignition limits in a leaner mixture state, and the operating conditions have a greater degree of freedom. The amount of methanol added to the detergent is more suitable at 20-25 parts. If the amount of methanol is too high, it is easy to cause corrosion of internal combustion engine parts.

[0083] 3) The choice of fatty alcohol polyoxyethylene (3) ether is to use its oil-soluble surfactant to reduce the surface tension...

Abstract

The invention relates to a fuel-cleaning agent and a preparing method for the agent, which comprises by weight water 5 portions, triethanolamine 3 portions, methanol 13 portions, n-butanol 16 portions, ethylene glycol monobutyl ether 39 portions, ethylenediamine 7 portions, polyoxyethylene nonyl phenyl (4) ether 7 portions, fatty alcohol (3) ether 4 portions, dodeca ammonia poly oxy ethylene ether 3 portions, and oil thanol amide 3 portions. The agent is prepared by the following procedures: adding the 5 portions of water into a vessel; adding 39 portions of ethylene glycol monobutyl ether, 3 portions of triethanolamine, 12 portions of methanol, 16 portions of n-butanol while agitating; adding 7 portions of polyoxyethylene nonyl phenyl (4) ether after agitating, 3 portions of fatty alcohol (3) ether, 3 portions of dodeca ammonia poly oxy ethylene ether, and 7 portions of ethylenediamine; adding 3 portions of oil thanol amide after reaction; agitating, and keeping still. The invention has an obvious and rapid cleaning speed, is good for reducing oil consumption, improving fuel utilization, and reducing the emission of harmful substance in the tail gas, and is energy saving and environmental friendly.

Description

technical field [0001] The invention relates to a fuel oil detergent and a preparation method thereof. Background technique [0002] According to the statistics of the environmental protection department, 70% of the pollution sources that cause the "greenhouse emission effect" come from the exhaust emissions of motor vehicles. Not functioning properly, resulting in inefficient use of fuel, so fuel detergent must be added to the fuel. However, if inferior fuel detergents are used, the amount of harmful exhaust gases emitted by the vehicle will more than double, and at the same time there will be adverse effects such as increased fuel consumption and abnormal damage to the engine. [0003] The additives that play a major role in existing fuel detergents are specific high-molecular organic amine compounds and surfactants. The principle of action is as follows: first use demulsification technology to form a non-emulsified environment in gasoline, and then use carbon removal tec...
