Abstract
The invention discloses a diesel additive, which consists of the following components in percentage by mass: 60 to 75 percent of a cetane number improver, 5 to 12 percent of benzotriazole, 3 to 8 percent of diphenylamine and diphenylcarbamide, 5 to 10 percent of naphthenic acid and 5 to 10 percent of iso-octyl alcohol. The diesel additive is prepared by proportionally mixing the components and stirring the components for 30 to 60min at 20 to 25 DEG C. The cetane number improver consists of the following components in parts by mass: 25 to 30 parts of amyl nitrate, 25 to 30 parts of ethyl nitrate and 10 to 15 parts of 2-ethylhexyl nitrate.
Description
Technical field
The invention provides a kind of diesel-dope, relate in particular to a kind of diesel-dope that can improve diesel cetane-number.
Background technology
In recent years, the day by day increase of international community to diesel oil demand, and limited diesel oil resource reduces increasingly, and occurred that diesel oil is under-supply, the trend of price increase.Because the alkane molecule amount of diesel component is larger, in the time of internal combustion engine, the rate of combustion of diesel oil is not high enough in addition, and combustionproperty is good not, and this has not only increased oil consumption, and has deepened the pollution level of exhaust to air.Therefore the problem such as use and environment protection of diesel oil, receives people's concern.Fuel oil scientific and technological industry circle strengthens the research and development dynamics to diesel-dope one after another both at home and abroad, to improve the combustioncharacteristics of motor spirit, reaches energy-conservation and object environmental protection.
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.Therefore, developing efficient, energy-conservation diesel-dope is subject to people's attention.
Summary of the invention
The object of the present invention is to provide a kind of diesel-dope; described additive can reach protection engine behaviour to diesel-engine vehicles, realize the more perfect of diesel oil and burning more completely, thereby reaches decarbonizing, saves fuel oil, reduces discharge, strengthens effect of power etc.
For achieving the above object, the present invention adopts following technical scheme:
A kind of diesel-dope, is made up of by massfraction following component:
Above-mentioned each component is mixed in proportion, and 20 ~ 25 ℃ are stirred 30 ~ 60min, obtain diesel-dope.
In technical scheme of the present invention, described cetane number improver is composed of the following components by mass parts:
25 ~ 30 parts of amyl nitrates
25 ~ 30 parts of ethyl nitrates
10 ~ 15 parts of 2-ethylhexyl nitric ethers
Diesel-dope provided by the invention is mainly used in improving diesel-fuel cetane number.Diesel cetane-number is the important indicator of evaluating the quality of diesel oil.Improve diesel-fuel cetane number and can shorten diesel oil delay period, improve the starting characteristic of diesel oil; The spontaneous ignition temperature of diesel oil, improves flammability.
Main component in additive provided by the invention is nitrate compound, this compounds has heat sensitivity, easily resolves into free radical or oxygenatedchemicals under high temperature, and in the time of diesel combustion, makes hydrocarbon oxidation, improve chain trigger rate, thereby improve the fire behaviour of fuel.
Than prior art, diesel-dope provided by the invention has improved diesel-fuel cetane number, and the diesel-fuel cetane number that has made to add diesel-dope of the present invention can meet international standards; And due to adding of pentanoic and diphenyl urea, improve the stability of diesel-dope of the present invention, made the burning of diesel oil safer; Make diesel-dope provided by the invention can reach the effect of decarbonizing, saving fuel oil, reduction discharge, enhancing power etc.; And diesel-dope consumption provided by the invention is little, additive in mass ratio: diesel oil is that 1:1000 use can make cetane value reach required standard.
