Abstract
The invention relates to an ashless additive for a diesel engine and the application of the ashless additive, and belongs to the technical field of diesel additives. The ashless additive for the diesel engine comprises the following components in percentage by mass: 50 to 83 percent of ethyl lactate and 17 to 50 percent of tert-butyl peroxy-2-ethylhexyl carbonate. The ashless additive can be used for improving the combustion performance of diesel and fulfilling the aims of saving the diesel and reducing the emission of harmful substances after combustion used as an anhydrous metal-free diesel additive.
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 is one of mankind important substance basis of depending on for existence and development, and the vital issue that the world today faces is fossil energy shortage, and the importance of green strategy improves efficiency of energy utilization and environment protection two broad aspect exactly.
Compare with petrol motor, diesel motor efficiency of combustion is high, wearing quality good, maintenance requires low, therefore diesel vehicle has numerous advantages to save energy, reduction energy security risk and minimizing greenhouse gas emission, but the problem that diesel oil exists as power fuel also can't neglect, particulate pollutant (PM) and NO that diesel engine is discharged
xbecause output is large, control techniques is complicated, become current research emphasis.
For the problems referred to above, concerning the vehicle having come into operation, mainly adopt diesel-dope, to improve fuel qualities to improve combustionproperty, to reduce hazardous emission, that this is considered to is convenient, one of effective technological treatment.Diesel-dope has diesel oil emulsifier, has grey additive and ashless additive at present.Although add the object that can reach energy-saving and pollution-reducing after diesel oil emulsifier, still have the technological difficulties of the aspects such as profit stability and corrosion; Contain the grey type additive of having of 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 metal compound) simultaneously, and its application is fallen under suspicion.
Summary of the invention
The object of the present invention is to provide a kind of multi-functional ashless diesel-dopes such as peace and quiet, dispersion, combustion-supporting and environmental protection that have, can be applied to using diesel car engine, play the effect that promotes diesel oil perfect combustion, reduces 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 diesel oil combustionproperty, reach the object of discharge of poisonous waste amount after saving diesel oil and reducing burning.
For an ashless additive for diesel motor, the quality percentage composition of its each component and each component is: ethyl lactate 50%～83%, peroxidation-2-ethylhexyl carbonic acid tert-butyl ester 17%～50%.
Preferably, the quality percentage composition of described ethyl lactate is 60.3%, and the quality percentage composition of described peroxidation-2-ethylhexyl carbonic acid tert-butyl ester is 39.7%.
The present invention also provides 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 diesel oil 1/499～1/249.
Preferably, in massfraction, the add-on of described ashless additive in diesel oil is diesel oil 2/623.
The present invention realizes as follows: the oxygen element in additive has played combustion-supporting effect in combustion processes, especially in the higher place of diesel oil concentration, improved the probability that diesel oil contacts with oxygen, diesel oil can more fully be burnt, thereby reach 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, and accelerate combustion process reaches fuel-economizing and the object that reduces pollutant emission.
Preparing ashless diesel-dope method of the present invention is to take respectively ethyl lactate and peroxidation-2-ethylhexyl carbonic acid tert-butyl ester by said ratio, and ultrasonic agitation device 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), diesel oil and additivated diesel oil are carried out to engine test bench characteristic and load-characteristic test, 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 decline 1.5%～3.4%, CO discharge decline 20%～55%, HC discharges 70%～89%, the NO that declined
xdischarge has declined 5%～20%, and smoke intensity declines 15%～33%.
Produce the equipment using 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 environment is not produced to secondary pollution, extensively applicable passenger-cargo truck that diesel oil is fuel, train, boats and ships, the tractor etc. of giving.
