Abstract

The present invention relates to a liquid fuel additive. The additive is prepared in a mode that a small amount of succinimide, amine oxides, synthetic ether, Paradyne, dialkyldiphenylamine, cresyl diphenyl phosphate N-Methyl-O-Phenylenediamine, zinc dialkylthiosulfate and N, N'-disalicylidene-1, 2-diamino cyclohexane; all components rapidly react with fuel oil at a high temperature and under high pressure to lead 'microexplosion reaction', which leads the sufficient combustion of the fuel; great pressure is generated to push a cylinder piston, and therefore, engine power is improved, and the discharge amount of CO and HC in tail gas is decreased. The liquid fuel additive is widely used for gasoline vehicles, diesel vehicles and all machines using liquid fuel, such as gasoline, diesel, etc.; the liquid fuel additive can prevent pollution, save fuel, improve the power of motor vehicles and extend the service life of engines.

Description

Liquid fuel additive

The invention belongs to the additive of machine, be specifically related to a kind of liquid fuel additive that can improve the liquid fuel combustion performance with liquid fuel.

Machine liquid fuels such as gasoline, kerosene, diesel oil and heavy oil are in use often owing to insufficient a large amount of wastes, the seriously contaminate environment of discharging of burning.Especially serious is, raising along with people's lives, expanding economy, the motor vehicle quantity of urban road sharply increases, a large amount of motor vehicle that these travel on urban road, continuously outwards a large amount of dischargings contain the tail gas of pollutent, the environment around seriously having polluted, meanwhile, also wasted a large amount of energy.

In order to solve the pollution of motor-vehicle tail-gas to environment, people once added additive to improve combustion efficiency of fuel oil in oil fuel, reduce the generation of pollutent; Or adopt the mechanism cleaning of off-gas, reduce the discharging of the pollutent of burning generation.But existing fuel dope as the gasoline antiknock tetraethyllead, though can improve combustionproperty, has polluted environment; Also have the what is called " emulsion fuel " of water mixing in gasoline or diesel oil to come fuel-economizing and reduce exhaust pollutant, but effect is undesirable, but also can cause that engine gets rusty, so do not see so far and promote the use of; And exhaust gas cleaner, though can reduce the discharging of pollutent in the tail gas, oil consumption increases on the contrary.

The object of the present invention is to provide a kind of liquid fuel additive, add a spot of this additive in the liquid fuel within, just can very improve liquid fuel combustion efficient effectively, thereby reach the purpose of saving fuel oil, reducing exhaust emissions.

Liquid fuel additive of the present invention is characterized in that its compositing range is:

100 liters of gasoline, diesel oil or kerosene,

Succinimide 0.02--0.06 gram,

Nacap (trade(brand)name) 3--6 gram,

Trimethylolpropane tris oleic acid ester 0.5--1.5 gram,

Paradyne (trade(brand)name) 0.5--4 gram,

Dialkyl diphenylamine 0.1--0.5 gram,

Cresyl diphenyl phosphate 0.02--0.05 gram,

N-Methyl-O-Phenylenediamine 0.1--0.3 gram,

Dialkyl dithio zinc sulfate 0.05--0.1 gram,

N, N '-two salicylidene-1,2 diamino-cyclohexane 0.3--0.8 gram,

Succinimide in the above-mentioned component can clean, disperse in-engine carbon distribution or incrustation as ashless detergent; Amine oxide (as the imported product of commodity Nacap by name) is an ignition dope, impels full combustion of fuel; Synthetic ester such as trimethylolpropane tris oleic acid ester are a kind of anti-wear agents, can prevent the engine component wear; Dialkyl diphenylamine is used to replace traditional deleterious metal detonation suppressor tetraethyllead as nonmetal octane promoter, improves the octane value of fuel oil, improves incendiary stability; Cresyl diphenyl phosphate is a smoke suppressor, can reduce the generation of harmful smog in fuel combustion process; Antioxygen scorch retarder N-Methyl-O-Phenylenediamine can prevent fuel oxidation coking in combustion processes; Dialkyl dithio zinc sulfate is thermal stabilizer, can prevent from high temperature to produce unsettled harmful material; Metal passivator N, N '-two salicylidene-1,2 diamino-cyclohexane can prevent the corrosion of engine metal parts; Paradyne (the importor name of an article) is a kind of additive that is used to improve the fuel combustion performance.

Above component joined respectively in 100 liters gasoline, diesel oil or the kerosene, in the presence of agitator, stirred at normal temperatures and pressures 3 hours, make it thorough mixing, liquid fuel additive of the present invention.

In use, in the oil fuel of each thousand volume that uses, only need to add about volume liquid fuel additive of the present invention, can in use bring about the desired effect.Be added with the oil fuel of liquid fuel additive of the present invention, under the High Temperature High Pressure of operating mode, the each component and the oil fuel of liquid fuel additive of the present invention interact rapidly, cause " microexplosion reaction ", make full combustion of fuel, and produce immense pressure, promote steam cylinder piston, increase engine power, reduce the quantity discharged of CO, HC in the tail gas.

Liquid fuel additive of the present invention, production technique are very simple, and both noiseless in the production process does not produce secondary pollutant yet; All use the machinery of liquid fuels such as gasoline, diesel oil, kerosene and heavy oil to be widely used in gasoline car, diesel vehicle and train, steamer, power station, oil-firing boiler etc., both can prevent to pollute, again can fuel-economizing, increase the power of motor vehicle, prolong the life-span of engine.
