Abstract
The diesel oil additive consists of: dodecyl methacrylate and diethylamino acrylate copolymer as clear dispersant 40-45 wt%; N,N'-desalicyl-1,2-propane diamine as antioxidant and metal deactivator 0.8-2 wt%; isooctyl nitrate as cetane number improver 7-10 wt%; phosphate as smoke eliminating agent 1-3 wt%; magnesium sulfonate as combustion assistant 11-14 wt%; lubricating antiwear agent 8-12 wt% and kerosene as diluent 22-27 wt%. It can save diesel oil by about 5 %, prolong the service life of diesel engine, improve lubrication, reduce wear, reduce tail gas and protect environment.
Description
The present invention relates to a kind of liquid fuel additive, particularly disclose a kind of diesel-dope, belong to the petrochemical technology field.
Production at diesel oil, transportation, storage, in the use, impurity is arranged in the diesel oil unavoidably, colloid and moisture, the crude oil in China structure belongs to high cured low sulfur type (with different) abroad, oilness is relatively poor in diesel engine work environment, do not burn owing to diesel oil is abundant in the diesel engine use, cause in nozzle and the combustion chamber carbon distribution increasing, influence the normal performance of its power, low-sulfur diesel-oil is bigger to the wearing and tearing of high-pressure pump, influence its work-ing life and cause environmental pollution and energy dissipation, the synthol that a kind of water and diesel oil are arranged, the physical index of this synthol is similar to diesel oil with chemical index, and saying so has no side effect to engine, and rate of economizing gasoline reaches 35～40%, with what this gave birth to many water-base diesel-oil additives and process patent arranged, routine Chinese patent application numbers 95100043.8; 95101011.5; 94116942.1; 94108047.1, do not say the effect of these additives, the water-base diesel-oil synthol has corrosive nature after all to engine, though the benefit of fuel-economizing effect 35～40% is arranged, benefit-risk balance still is more harm than good, therefore can't be in the same way.
Purpose of the present invention discloses a kind of diesel-dope, can fuel-economizing about 5%, reduce the exhaust emissions smoke intensity of diesel engine, and reduce environmental pollution, improve the mechanical output of diesel engine, prolong the work-ing life of diesel engine.
The present invention realizes like this, diesel-dope, it contains the multipolymer of detergent-dispersant additive lauryl methacrylate and diethylamino vinylformic acid ethyl ester (hereinafter to be referred as detergent-dispersant additive, antioxygen and metal passivator N.N1 two bigcatkin willows 1.2 propylene diamine, cetane number improver isooctyl ester nitrate, smoke suppressor phosphoric acid ester, ignition dope sulfonic acid magnesium, diluent kerosene down together),, its feature also contains lubrication anti-wear agent machine oil treatment agent at it, and the proportioning of each component is: (weight percent)
Detergent-dispersant additive: 40～45%
Antioxygen and metal passivator: 0.8～2%
Cetane number improver: 7～10%
Smoke suppressor: 1～3%
Ignition dope: 11～14%
Lubrication anti-wear agent: 8～12%
Thinner: 22～27%
Each component of diesel-dope stirs mixed at normal temperatures by proportioning.
Embodiment 1: a kind of diesel-dope, its each component and set of dispense ratio are: (weight percent)
Detergent-dispersant additive: 42%
Antioxygen and metal passivator: 1%
Cetane number improver: 8%
Smoke suppressor: 2%
Ignition dope: 12%
Lubrication anti-wear agent: 10%
Thinner: 25%
Said components stirs mixed at normal temperatures by proportioning, the quality standard that generates the diesel-dope product is: outward appearance: clear amber in color.
Density: 0.85～0.90
40 ℃ of kinematic viscosity: 8～10
Flash-point (remaining silent):＞55 ℃
Embodiment 2: a kind of diesel-dope, its component and set of dispense ratio are: (weight percent)
Detergent-dispersant additive: 44%
Antioxygen and metal passivator: 2%
Cetane number improver: 6%
Smoke suppressor: 1%
Ignition dope: 14%
Lubrication anti-wear agent: 8%
Thinner: 25%
After the said components proportioning, stir mixedly at normal temperatures, generate the product of the quality standard identical with embodiment 1.
The diesel-dope product of embodiment 1, embodiment 2 uses 0.5% through Shanghai water transport energy utilization monitoring center in No. 0 solar oil.Additive of the present invention also moves after 3 hours diesel engine bench comparative test result when not adding its additive, the average rate of economizing gasoline of four kinds of operating modes (50%, 75%, 90%, 100%) except that 25% load: propulsive characteristics is 1.34%, and part throttle characteristics is 1.46%; Real ship detects: rate of economizing gasoline 4.6%.
Product of the present invention removes the carbon distribution that has in cleaning oil nozzle and the combustion chamber, makes diesel oil atomization better, and it is more abundant to burn, and improves the diesel oil calorific value, improves oilness at the situation of diesel engine, improves mechanical output.Its result of use is to save diesel oil about 5%, prolongs the mechanical work-ing life of diesel engine, the lubricated improvement, and wearing and tearing reduce, and reduce the smoke emission of diesel engine vent gas simultaneously, the protection environment.
