Description
Technical field
The present invention relates to a kind of gasoline cleaning agent, preparation method and its usage.
Background technology
Along with the fast development of automotive industry, the recoverable amount of China's automobile is increasing sharply.While bringing convenience to people's production, life along with automobile, also increase the consumption of petroleum resources and the discharge of tail gas objectionable impurities.How to allow motor car engine be in good work condition state for a long time, fuel gasoline is burnt fully, reduce oil consumption, improve discharge.This just necessarily requires the fuel oil inlet system long-lasting cleanliness of motor car engine.For this reason, effective gasoline cleaning agent must be added in clear stipulaties motor spirit in national environmental standard.
And in Hyundai Motor technology, fuel electron spraying system (PFI) instead of the automobile of carburettor comprehensively, direct spray petrol engine in cylinder (GDI) technology is also popularized gradually, the fuel injector aperture of these engines is very little, working temperature is higher, be easy to be completely clogged with soot, cause the problems such as atomization badness, fuel feeding are not smooth, oil consumption increase, deterioration of emission.Along with the development of modern engine machine technology, the application of turbo-charging and discarded recirculation system is increasingly extensive, the thermal load of engine is increasing, the deposit problems of engine intake valve is also more and more serious, and inlet valve deposits causes cylinder seal not tight, causes engine mixed gas to leak, cylinder drops, power reduction, has a strong impact on the fuel economy of engine, dynamic property and the feature of environmental protection, and the overall performance of engine is declined.The not good increase that also can cause deposition of combustion chamber of engine of performance of gasoline cleaning agent, the total settling of gasoline engine combustion chamber significantly increases, the compression ratio of engine can be made to increase, and not easy heat radiation, raised by the gas temperature causing burning in interior compression, OR Octane Requirements increases, and increases the mechanical disturbance between top land and cylinder cap time serious, produce " carbon engine knock ", finally will cause engine consumption increase, deterioration of emission.Therefore higher requirement is had to the performance of gasoline cleaning agent.
Prior art has open a kind of fuel oil additive, and the polyetheramine of the ethylene glycol of the sanitas by 10%, the octane enhancer of 10-20%, 5-20%, the acetone of 10-20%, 3-5%, all the other are solvent composition.Wherein octane enhancer is the xylene mixture of 4:4:6:1:1 by mass ratio: MTBE(dimethyl tertiary butyl ether): decane: ferrocene: octanol forms, solvent is dimethylbenzene.Dynamic performance can be improved to a certain extent and reduce exhaust contaminant content, but it removes the DeGrain of engine nozzle, combustion chamber and inlet valve carbon distribution, and owing to employing xylene aromatic hydrocarbons, this type of material is not only harmful, and distinctive unsaturated link(age) is oxidizable, colloid in fuel is increased, makes carbon distribution increase on the contrary.The ferrocene simultaneously contained in additive generates ferric oxide after combustion and stays in combustion chamber and also not easily taken out of, adds the wearing and tearing of engine.Also have open in order to suppress prime the fuel system to produce settling, can effectively clean vehicle in use nozzle burner, the sedimental gasoline cleaning agent that intake valve and combustion chamber have produced, comprise the high surface polyetheramine of 10-85%, the high surface PIBA of 5-20%, 5 ~ 35% carry oil, the solvent oil of 0-30% and the oxidation inhibitor of 1.0-3.0%, the rust-preventive agent of 0.5-1.5%, the sanitas of 0.5-1.0%, the emulsion splitter of 0.1-0.5%, its solvent oil is selected from trimethylbenzene, durene, alkylbenzene, aromatic hydrocarbon oil, kerosene, isooctyl alcohol, glycol ether equal solvent, can the automatic cleaned engine oil nozzle of free removal, intake valve, fuel oil room settling, motor car engine is made to be in good working order for a long time, and keep clean, improve the quality of motor spirit, motor car engine is burnt more abundant, improve thermo-efficiency.But its solvent oil selected such as trimethylbenzene, durene, alkylbenzene, aromatic hydrocarbon oil is not only harmful, and distinctive unsaturated link(age) is oxidizable, colloid in fuel is increased, carbon distribution is made to increase on the contrary, make its de-carbon not reach ideal effect, and it use a large amount of functional additives, cost is also higher, the gasoline cleaning agent addition in the oil of preparation is generally 1000ppm-3000ppm, and addition is larger.
Summary of the invention
Undesirable and the technical problem that cost is high, usage quantity is large of the clean de-carbon effect that the invention solves existing gasoline cleaning agent, provide a kind of can more effective removing engine nozzle, combustion chamber and inlet valve carbon distribution; Improve fuel economy, reduce oil consumption, prevent the wearing and tearing of engine; Increasing service life of engine, reduces maintenance cost and cost is low, less usage quantity can reach ideal effect in the oil gasoline cleaning agent, Its Preparation Method And Use.
First object of the present invention is to provide a kind of gasoline cleaning agent, comprise and there is surface-active polyetheramine, the octane enhancing additive of gasoline and alkane solvents oil, with the volumn concentration of gasoline cleaning agent for benchmark, the volumn concentration of described polyetheramine is 30-70vol%; The volumn concentration of the octane enhancing additive of described gasoline is 3-20vol%; The volumn concentration of described alkane solvents oil is 25-60vol%.
Second object of the present invention is to provide the preparation method of above-mentioned gasoline cleaning agent, comprise by the polyetheramine of high surface, the octane enhancing additive of gasoline and alkane solvents oil, room temperature or be no more than 60 DEG C condition under be uniformly mixed.
3rd object of the present invention is to provide the purposes of above-mentioned gasoline cleaning agent, joins in gasoline by 500-2000ppm dosage.
The present inventor surprisingly finds, by of the present invention, there is surface-active polyetheramine, the octane enhancing additive of gasoline and the mixing of alkane solvents oil three kinds of essential substance, there is stronger clean-up performance, the more effective removing engine nozzle of energy, combustion chamber and inlet valve carbon distribution; Improve fuel economy, reduce oil consumption, prevent the wearing and tearing of engine; Increasing service life of engine, reduces maintenance cost, and need not by the functional additive of costliness, and cost is low, and less usage quantity can reach ideal effect in the oil simultaneously, even only can realize the strong cleaning effect of the present invention with interpolation 500ppm.Inferring may because the interaction energy between three materials significantly improves its clean de-carbon performance; And there is surface-active polyetheramine itself carbon distribution also can be prevented to be deposited on body surface shield, also can be coated by the soot particles in oil, prevent soot particles from continuing increase and play compatibilization; The octane enhancing additive of gasoline itself can improve the octane value of gasoline simultaneously, good with the consistency of polyetheramine and alkane solvents oil, can play its capability of antidetonance preferably, reduces the vibrations of engine, makes sound; Particularly not only cost is low for alkane solvents oil, pollution-free, and specific heat of combustion is high, and burning liberated heat is large, and the greasy filth of combustion chamber, carbon distribution can be made under high-temp combustion to become ash content, and then discharges engine, and noresidue, de-carbon effect is more obvious.Simultaneously the consistency of gasoline cleaning agent of the present invention and various gasoline is good, can be applicable to various model petrol motor and various trade mark gasoline and various weather condition.Method of the present invention is simple and easy to realize, easy large-scale production and application.
