Abstract
The invention discloses a compound diesel additive. The additive is prepared from the following components in parts by mass: 6-10 parts of 2-ethylhexyl nitrate, 1-3 parts of metal deactivator, 3-8 parts of antiwear agent, 15-22 parts of dispersing agent and 8-18 parts of cold flow improver. The compound diesel additive is prepared through mixing the components at the ratio and stirring for 15-30 minutes at a temperature of 20-25 DEG C. The metal deactivator is combined N,N-metal deactivator; the antiwear agent is fatty acid-fatty acid ester-fatty acid amine mixture; the dispersing agent is tetralin; the cold flow improver is ethylene-isobutyl acrylate.
Description
Technical field
The invention provides a kind of diesel-dope, relate in particular to a kind of composition diesel-dope that can improve the multiple performance of diesel oil.
Background technology
Along with being widely used of diesel engine, the positive increase year after year of the consumption of diesel oil.But a large amount of consumption of diesel oil also will inevitably cause the further aggravation of vehicular discharge nuisance.Because discharge has a strong impact on ecotope, human health and Economic development, national governments have formulated strict Abgasgesetz in succession, the noxious emission of restriction diesel vehicle.Therefore the oil consumption and the pollution that, further reduce diesel-engine road vehicle are current problem demanding prompt solutions.In numerous solutions, use the method for diesel-dope not changing vehicle and engine structure, do not increase under the condition of equipment yet, by changing the physical property of fuel, make fuel be able to abundant burning, thereby realize energy-conservation and emission abatement.
Improve diesel motor fuel burning quality a lot of with the method for minimizing tail gas pollution, using additive is one of economy and effective means.At present, diesel-dope of the prior art exists function singleness,, exhaust emissions objectionable impurities large to the corrodibility of engine interior to reduce the shortcomings such as not obvious.
Summary of the invention
For overcoming problems of the prior art; the invention provides a kind of composition diesel-dope; described additive can overcome the various problems existing in diesel combustion process simultaneously; diesel-engine vehicles is reached protection engine behaviour, realizes the more perfect of diesel oil and burning more completely, thereby reach decarbonizing, save fuel oil, reduce discharge, strengthen effect of power etc.
For achieving the above object, the present invention adopts following technical scheme:
A kind of composition diesel-dope, is made up of following components in mass portion:
Above-mentioned each component is mixed in proportion, and 20 ~ 25 ℃ are stirred 15 ~ 30min, obtain composition diesel-dope.
2-ethylhexyl nitric ether can improve diesel-fuel cetane number, thereby improves the combustionproperty of diesel oil.
In technical scheme of the present invention, described metal passivator is combination N, N-bis-salicylidene propylene diamine.In diesel oil can there is catalytic oxidation in the metallic compound such as dissolved copper of contained trace, and contained acidic impurities component in oil, in refining, storing and use procedure, contact with the metal parts such as copper in mechanical means, reaction generates the metallic compounds such as the micro-copper of solubility.Therefore, in technical scheme of the present invention, add metal passivator, the metallic compounds such as the copper in diesel oil are converted into inner complex, make it not generate the compound with catalytic activity, thus passivation or inactivation.
In technical scheme of the present invention, described anti-wear agent is lipid acid-fatty acid ester-fatty acid amine mixture.Anti-wear agent add the wearing and tearing that can prevent diesel injection system.
In technical scheme of the present invention, described dispersion agent is tetraline.Because crackate component in current diesel oil accounts for quite large share, in standing storage process, unavoidable oxidation generates insoluble colloid, residue and lacquer deposit.These impurity are easy to blocking filter and nozzle etc., and cigarette ash in exhaust is increased, and cause power to decline.Adding of dispersion agent, can make insoluble substance in diesel oil, keep dispersion suspension state, so as not to the key position of engine capable become lacquer deposit, also can guarantee that combustionproperty is good simultaneously, reduce free air delivery, reduce and pollute.
In technical scheme of the present invention, described low temperature flow promoter is ethylene-acrylic acid isobutyl ester.Ethylene-acrylic acid isobutyl ester has a significant effect to improving diesel oil at low-temperature use properties.It has the three-dimensional effect that covers shielding and disperse, and it is added in diesel oil, can the wax nucleus or the trickle crystal grain that form at low temperatures be wrapped up very completely, even if temperature reduces, crystal grain can not be grown up again.And the crystal grain dispersion of being wrapped up by solid is fine, can effectively reduce the condensation point of diesel oil, improve the low-temperature fluidity of diesel oil.
Than prior art, composition diesel-dope provided by the invention is made up of various ingredients, and Each performs its own functions for each component, but have synergy.Composition diesel-dope provided by the invention can effectively improve the combustionproperty of diesel oil, keeps cylinder clean, reduces incomplete combustion, reduces the discharge of the objectionable impuritiess such as CO, NOx, HC and soot in diesel motor exhaust, reaches the object of energy-saving and emission-reduction.
