Abstract

The present invention relates to vehicular fuel, and is especially one kind of clean gasoline fuel capable of replacing gasoline for use in vehicle. The clean gasoline fuel is mixture of additive 9-22 %, methanol 20-80 % and light oil, naphtha, solvent oil or gasoline 5-62 %. The clean gasoline fuel meets the standard of no-lead gasoline, has CO exhaust and hydrocarbon exhaust 46.2 % and 69.8 % lower than that of gasoline separately, and may be used in replacing vehicular gasoline.

Description

A kind of clean gasoline fuel

Technical field

The present invention relates to a kind of vehicle fuel, particularly a kind ofly can substitute the buy car in installments clean gasoline fuel of a use of GB gasoline.

Background technology

Because petroleum resources non-renewable and to the continuous exploitation utilization of petroleum resources, by the oil preparation the GB petrol delivery growing tension that seems, thereby caused the various appearance that are used for substituting the vehicle fuel of GB gasoline.But more or less all there is certain defective in these vehicle fuels, do not reach the standard of national white gasoline as some technical indicator of alternative fuel, perhaps alternative fuel burning back exhaust emissions can not up to standardly cause environmental pollution, some the structure alternative fuel that perhaps needs to change vehicle motor could normally be used etc., does not promote the use of so that these vehicle alternative fuels so far can be general.

Summary of the invention

The purpose of this invention is to provide a kind of every technical indicator and all meet national white gasoline standard, and carbon monoxide and the low clean gasoline fuel of hydrocarbon emission amount, make it can substitute existing GB gasoline fully as vehicle fuel.

Clean gasoline fuel of the present invention is prepared by following method:

Detonator with 11～29%, 10～21% solubility promoter, 39～62% power toughener and 9～22% mutual solvent mixed at normal temperatures and pressures additive, the lightweight oil of this additive of 9～22%, 20～80% methyl alcohol and 5～62% or petroleum naphtha or solvent oil or GB gasoline are mixed, described per-cent is weight percentage again.

The weight percent that is used to prepare each material of additive is:

Detonator 20% solubility promoter 15% power toughener 50% mutual solvent 15%.

The weight percent of described additive, methyl alcohol and lightweight oil or petroleum naphtha or solvent oil or GB gasoline is:

Additive 12% methyl alcohol, 50% lightweight oil or petroleum naphtha or solvent oil or GB gasoline 38%.

Described detonator is an octane, and solubility promoter is a hexanaphthene, and the power toughener is second-methylbutane, and mutual solvent is a polyethylene vinyl acetate-2.

Chinese People's Liberation Army logistics engineering detecting center is that No. 93 clean gasoline fuel of the present invention is checked to model, inspecting standard: GB/T5487, GB/T 8017, GB/T380, GB/T5096, GB/T11132, GB/T260, GB/T259, GB/T509, GB/T3536, GB/T511, GB/T8020, GB/T8017, GB/T8018, GB/T1792, SH/T0174, assay such as table 1: " survey report " (2005) quality inspection (oil) word 341-2 number.

Conclusion: when clean gasoline fuel of the present invention uses at vehicle 46.2% of the quantity discharged average out to same model GB gasoline of CO, 69.8% of the quantity discharged average out to same model GB gasoline of HC.

In sum, the every technical indicator of clean gasoline fuel of the present invention all meets the standard of national white gasoline, uses the Vehicular exhaust carbon monoxide and the hydrocarbon emission amount of clean gasoline fuel of the present invention low than GB gasoline.

Clean gasoline fuel of the present invention also has following advantage:

One, sufficient combustion, its octane value height, so powerful, if use proper, (car) oil consumption saves 10～20% than GB gasoline on high compression engine, and (oversize vehicle) oil consumption saves 5～10% than GB gasoline on low compression ratio engine, and some dirts and carbon distribution in solubilized automobile oil circuit and the cylinder, guarantee the engine works better, prolong the work-ing life of vehicle.

Two, directly add in the automotive oil tank and can use, need not change, and need not clean fuel tank vehicle motor.

Three, can use separately, also can mix use by arbitrary proportion with the GB gasoline and the ethanol petrol of same model; Its anti-water, antifouling property are strong, and water repelling property reaches 3～5%, and antifouling property reaches 1～3%; Good stability is deposited eight months no turbid phenomenon.

Four, no rubber corrosion, easily start winter, the Rhizome of Decumbent Corydalis air-resistance phenomenon.

Five, raw material is easily purchased, and is with low cost, and its cost (No. 93) is about 4780 yuan/ton, far below 6920 yuan/ton of GB gasoline (No. 93) retail prices, 6300 yuan/ton of wholesale prices.
