Abstract
The invention belongs to a fuel substitute for internal combustion engine and relates to a high-proportion methanol diesel for vehicle. The invention is made of 70 weight percent to 85 weight percent of methanol, 10 weight percent to 25 weight percent of diesel and 5 weight percent to 10 weight percent of additive. The invention has the advantage that the coalified fuel of methanol is used as the main raw material; thus the invention can reduce the excessive dependence on petroleum and reduce the emission of harmful substances in the combustion process of diesel in the internal combustion engine.
Description
Technical field
The invention belongs to oil engine alternative fuel class, relate to a kind ofly through the miscible vehicle high-ratio methanol diesel oil of additive, promptly 70% (W) forms to the additive (comprising the priming mixture of market purchasing, combustion-supporting purification agent, tensio-active agent, cosurfactant, Fatty Alcohol(C12-C14 and C12-C18), corrosion inhibition for metal inhibitor and lubricant) of the diesel oil and 5% (W) to 10% (W) of the methyl alcohol, 10% (W) to 25% (W) of 85% (W) is fused.
Background technology
At present, the both at home and abroad employing changes diesel motor structure such as fuel dual system more, spark-ignition system, and the burning high-ratio methanol diesel oil is mixed in enforcements such as exhaust cycle system.But do not change engine structure, directly use 85% (W) high-ratio methanol diesel oil, compression-ignition, and good in economic efficiency, methyl alcohol substitutes the diesel oil ratio and reaches 1.4, does not appear in the newspapers.
The low heat value of methyl alcohol only diesel oil 46%, its theoretical mixture gas calorific value is a little less than diesel oil.The air-fuel ratio of diesel oil is 2.26 times of methyl alcohol air-fuel ratio, and the low heat value of diesel oil is low-calorie 2.14 times an of methyl alcohol; Make methyl alcohol and diesel oil have same equipower, the consumption of methyl alcohol must be more than the twice of diesel oil.The theoretical calorific value of diesel oil is 1.03 times of the theoretical calorific value of methyl alcohol, and this is under the equal volume condition, does not change engine structure, reduces the alternative prerequisite than (nail alcohol substitutes diesel oil) of methyl alcohol.
2. under the normal temperature, methanol diesel-oil is than the easy layering of methanol gasoline, and high-ratio methanol diesel oil is than the easier layering of gasoline of high proportion methanol; Methyl alcohol is being blent (blending), storing, easily moisture absorption in metaideophone and the driving process, and easy layering when water-content 〉=0.2% reduces (environment) use temperature than the water-content easier layering that exceeds standard; Different methanol diesel-oil ratios have variation because of water content is different with use temperature, additive composition and methanol diesel-oil ratio are not suitable for also can layering.Satisfy water-content simultaneously and reach 5% to 10%, use (environment) temperature to reach-10 ℃ to-35 ℃, need to increase additive amount or cost, adjust additive and form, can reach the suitability price ratio.
3. diesel engine belongs to compression-ignition, is limited to 48 under its cetane value, and the methyl alcohol cetane value is 3, and its hot spontaneous ignition temperature is 470 ℃, far above 220 ℃ to 270 ℃ of the hot spontaneous ignition temperatures of pure diesel oil; Use for diesel engine diesel oil, its compression-ignition (i.e. compression end) temperature 〉=750 ℃, high-ratio methanol diesel oil, its compression-ignition (i.e. compression ends) temperature 〉=950 ℃; The gasification latent heat of methyl alcohol is 4.4 times of diesel oil, its theoretical gasification temperature (no external heat source) is-122 ℃, when testing at normal temperatures, frost appears in the basal surface of carburettor, methyl alcohol almost can not gasify in inlet pipe, be difficult to form inflammable mixture, the flash-point of methyl alcohol is 11 ℃ to 12 ℃, almost is difficult to light under this temperature.85% (W) high-ratio methanol diesel oil MH85 cetane value is 9.5, about 140 ℃ of its theoretical gasification temperature.As seen by above-mentioned, high-ratio methanol diesel oil is directly used in the diesel engine compression-ignition, and especially cold start-up is unusual difficult, or even impossible; Not changing engine structure, use high-ratio methanol diesel oil to realize compression-ignition, is our times scientific workers' biggest obstacle.
4. high-proportion methanol makes the alcohol hydrocarbon fuel viscosity degradation, easily causes component wear.The viscosity that requires high-ratio methanol diesel oil is near diesel oil; Require alcohol hydrocarbon fuel to avoid crossing and lowly flow into housing bottom and lubricating oil forms diluted emulsified machine oil because of cylinder temperature.
5. methyl alcohol has corrodibility to metallic substance such as copper, iron, aluminium, zinc, lead, non-metallic material such as the pipeline of fuel transfer system, sealing member, Equipment In Oil Service Station is had swelling action, even cause be full of cracks.These problems are used on the automobile very dangerous if do not solve.
Summary of the invention
1. influence the low heat value of being not only fuel of engine operation, and be the calorific value of gas mixture.The compression ratio of diesel engine is far above petrol motor, and compression ratio improves a unit, and rate of economizing gasoline improves 4 units; The thermo-efficiency of diesel engine is far above petrol motor, and thermo-efficiency improves 4-5 unit, and rate of economizing gasoline also can improve 4-5 unit; Under same compression ratio, the power the during work of MH85 lean-burn increases by 8%～15% than petrol motor, and the consumption minimization rate is than petrol motor low 3%～5%.
2. engine structure need be do not changed, the GB diesel oil of corresponding label can be directly substituted.
3. mutual solubility is good, even water content reaches 5%, also not stratified below-25 ℃.
4. can promote diesel quality, as: 0# ,-10# diesel oil, after dissolving each other to 85% (W) methyl alcohol with 70% (W) in proportion, can promote for be equivalent to-10# ,-25# diesel oil.
5. environment protecting is good: diesel motor uses noxious emission CO, the HC of methanol diesel-oil and NOx content all obviously to reduce, methanol diesel-oil emission smoke intensity fall surpasses 80%, be to solve automobile pollution, particularly solve one of effective way of city environmental pollution.
6. stand rate of economizing gasoline: press 0# GB diesel oil configuration MH85, be 17, with power with diesel engine bench comparative test result under the working condition be at compression ratio through the 16.2KW diesel engine: the alternative ratio that methanol diesel-oil (MH85) substitutes diesel oil is: 1.4: 1.
