Description

A kind of efficient emission-reducing state IV diesel quality elevators
Technical field
The present invention relates to a kind of fuel oil additives, particularly a kind of quality-improving agent for state's IV diesel oil.
Background technology
At present, frequent haze weather has become the main atmosphere pollution problem that China faces.The generation of haze with it is motor-driven The nitrogen oxides of vehicle discharge（NOx）, fine particle（PM2.5）Wait pollutants directly related, the wherein NO of emission of diesel enginexIt is close The 70% of vehicle mass exhaust total quantity, particulate matter are even more more than 90%.The consumption of diesel oil just increases year by year, and a large amount of diesel consumption causes The discharge of vehicle nuisance is further exacerbated by.Therefore diesel emission abatement is the most important thing that haze is administered.Do not change vehicle with Engine structure under conditions of also not increasing equipment, can change the physical property of fuel using diesel fuel additives, fuel is made fully to fire It burns, so as to fulfill energy saving and purification discharge.Therefore, the diesel fuel additives for developing efficient emission-reducing is the emphasis studied from now on, is solved One of Main way of haze weather.
Diesel fuel additives both domestic and external is broadly divided into three classes：First, energy saving additive, main purpose is to improve The power of engine reduces oil consumption；Second is that environment protection additive, main purpose is the discharge of purifying engine, reduces pollution； Third, comprehensive additive, content not only energy saving but also that harmful substance in engine exhaust can be reduced.Due in conventional diesel engine Burning be difficult to take into account PM2.5 and NOxDischarge improves diesel quality performance, while it is gentle to reduce PM2.5 by quality-improving agent State pollutant emission simultaneously saves the method that fuel oil is worth exploration.Due to particulate matter and NO in diesel engine combustionxGeneration It mutually restricts, is only possible to obtain comprehensive efficient emission-reducing effect using composite additive.At present, applied to state's IV bavins Oil can reduce HC, CO, PM2.5 and NO simultaneouslyxAdditive have not been reported.
Invention content
The present invention seeks to fill a hole in the market, a kind of diesel oil addition of high-performance high-quality for state's IV diesel oil is provided Agent.
Technical solution disclosed by the invention is：This quality-improving agent for state's IV diesel oil includes following parts by weight Compound：
3-8 parts of isooctyl ester nitrate
5-10 parts of lubricant
12-18 parts of polyisobutene succinimide
10-15 parts of polyetheramine
8-12 parts of plastic of poly vinyl acetate
10-25 parts of dimethyl carbonate
5-10 parts of polymethoxy dimethyl ether
5-10 parts of dispersant
16-24 parts of solvent naphtha.
The wherein described lubricant is one or more of monooctyl ester, the own ester of acetoacetate, aphthenic acids, hexyl oleate；Point Powder is one or more of vinyl alcohol butyl ether, triethylene tetramine, triethylamine, vinyl alcohol butyl ether and Span-80；Solvent naphtha is 120#, 200# solvent naphtha one or two therein.
The preparation method of this quality-improving agent for state's IV diesel oil, have main steps that by the component of aforementioned weight according to Heating is reacted 20 minutes under the conditions of 40 DEG C in secondary addition reaction kettle.
The application method of this quality-improving agent for state's IV diesel oil is by the aforementioned diesel quality elevator prepared According to diesel quality elevator:State IV diesel oil=1:The volumetric ratio acceding state IV diesel oil of 1000-2000, stirs evenly.
Compared with prior art, product of the present invention is in neutrality, and any acid and alkali corrosion will not be caused to diesel engine.Product Fuel efficiency can be effectively improved, while reduces the greasy property that frictional dissipation in cylinder improves diesel oil, promotes fuel economy；From And reach while reduce PM10, PM2.5, CO, HC and NOxDischarge and reduction fuel consumption, increasing service life of engine, have Important actual application value.
Specifically, the present invention has following features：
1st, this product contains series polymeric body organic matter, without the harmful components such as metal and phosphorus, chlorine, contains dispersant, product tool There are good " intersolubility " and " anti-corrosive properties ".
2nd, the addition of isooctyl ester nitrate can improve the Cetane number of diesel oil, improve the combustibility of diesel oil, improve diesel oil hair Fire shortens ignition time, reduces burning point, improves locomotive thermal condition dynamic property.
3rd, polyisobutene succinimide has the surfactant of amphiprotic group, passes through hydrophilic radical and lipophilic group Collective effect promotes fuel spray finer and smoother, unit interval oil spout particle flux is made to attenuate, so that its total specific surface area increase, makes Micro-droplet of oil accelerated expansion under high temperature action gasifies, and make combustion gas mixing uniform, so as to accelerate its evaporation rate, ignition temperature It reduces, so that increased flame speeds, make flame propagation velocity orderly, burning is more abundant, and fuel thermal efficiency improves, and reduces combustion Oilconsumption.
4th, the addition of polyetheramine, dimethyl carbonate makes fuel oil adequately all burn, and reduces the generation of carbon particle, improves Burning velocity makes thermal discharge reach cycle thermal discharge.It is mainly shown as enhancing power, reduces oil consumption, reduces exhaust emission row High-volume.
5th, the addition of plastic of poly vinyl acetate makes cold vehicle easily start, reduces noise, extending the service life of engine； Due to the addition of polymethoxy dimethyl ether, diesel oil oxygen content can be improved, increases the Cetane number of diesel oil, improves that engine is cold to be opened Dynamic property achievees the purpose that combustion-supporting reduction smoke intensity.
6th, the addition of polyisobutene succinimide can be removed effectively and inhibit engine fuel system and combustion chamber deposit Substance（Such as carbon distribution, colloid）, the service life of engine fuel oil system parts is improved, prevents fuel feed pump plunger, oil burner Phenomena such as sintering, occurs.
