Description
Technical field
The present invention relates to a kind of ashless additive for diesel motor and application thereof, belong to diesel-dope technical field.
Background technology
The energy be the mankind depend on for existence and development important substance basis one of, the vital issue that the world today faces be fossil energy shortage, the importance of green strategy improves efficiency of energy utilization and environment protection two broad aspect exactly.
Compared with petrol motor, diesel engine combusts efficiency is high, wearing quality good, maintenance requires low, therefore diesel vehicle has numerous advantage to save energy, reduction energy security risk and minimizing greenhouse gas emission, but diesel oil also can't neglect as power fuel Problems existing, the particulate pollutant (PM) that diesel engine is discharged and NO
xbecause output is large, control techniques is complicated and become current research emphasis.
For the problems referred to above, concerning the vehicle come into operation, mainly adopt diesel-dope, to improve fuel qualities to improve combustionproperty, to reduce hazardous emission, this is considered to one of convenient, effective technological treatment.Current diesel-dope has diesel oil emulsifier, has grey additive and ashless additive.Although the object of energy-saving and pollution-reducing can be reached after adding diesel oil emulsifier, still there are the technological difficulties of the aspects such as profit stability and corrosion; Grey type additive is had containing metallic element, due to adding of metallic element, make cylinder, nozzle many places cause dust stratification, affect the performance of engine, its products of combustion can cause secondary pollution (comprising the discharge of metallic particles thing and toxic metals compounds) simultaneously, makes it apply and falls under suspicion.
Summary of the invention
One is the object of the present invention is to provide to have the multi-functional ashless diesel-dopes such as peace and quiet, dispersion, combustion-supporting and environmental protection, diesel automobile in use engine can be applied to, play the effect promoting diesel oil perfect combustion, reduce pollutant emission, to solve the deficiencies in the prior art.This ashless additive as a kind of anhydrous, without the diesel-dope of metal, can be used for improving the combustionproperty of diesel oil, reaching the object of discharge of poisonous waste amount after saving diesel oil and reducing burning.
For an ashless additive for diesel motor, the mass percentage of its each component and each component is: ethyl lactate 50% ~ 83%, the peroxidation-2-ethylhexyl carbonate tert-butyl ester 17% ~ 50%.
Preferably, the mass percentage of described ethyl lactate is 60.3%, and the mass percentage of the described peroxidation-2-ethylhexyl carbonate tert-butyl ester is 39.7%.
Present invention also offers the application of described ashless additive as diesel-dope, it is characterized in that: in massfraction, the add-on of described ashless additive in diesel oil is 1/499 ~ 1/249 of diesel oil.
Preferably, in massfraction, the add-on of described ashless additive in diesel oil is 2/623 of diesel oil.
The present invention realizes as follows: the oxygen element in additive serves combustion-supporting effect in combustion, especially in the place that diesel oil concentration is higher, improve the probability that diesel oil contacts with oxygen, diesel oil is more fully burnt, thus reaches the effect of fuel-economizing and reduction CO, HC and smoke emission; This ashless diesel-dope contains organo-peroxide in addition, after it joins diesel oil, provides free radical molecule, changes the elicitation procedure of chain reaction, accelerate combustion process, reaches the object of fuel-economizing and reduction pollutant emission.
Preparing ashless diesel-dope method of the present invention is take ethyl lactate and the peroxidation-2-ethylhexyl carbonate tert-butyl ester respectively by said ratio, and ultrasonic stirrer mixes, and makes transparent solution, obtains described ashless diesel-dope.
The present invention is according to GB/T18297-2001 (motor car engine method for testing performance), engine test bench characteristic and load-characteristic test are carried out to diesel oil and additivated diesel oil, after in process of the test, different fuel switches, the steady running sufficiently long time, to eliminate the impact of residual fuel in prime the fuel system.Under all structural parameter of diesel engine condition without any changes, fuel oil consumption 1.5% ~ 3.4%, the CO that declines discharges decline 20% ~ 55%, HC discharge and have dropped 70% ~ 89%, NO
xdischarge have dropped 5% ~ 20%, and smoke intensity declines 15% ~ 33%.
Produce the equipment that uses for the ashless additive of diesel motor provided by the present invention and technique simple, raw material is simple and easy to get, addition is little, close with the physical and chemical index of diesel oil itself, easy to use, oil soluble is good, good stability, and secondary pollution is not produced to environment, is extensively suitable for and gives the passenger-cargo truck, train, boats and ships, tractor etc. that diesel oil is fuel.
