Molecular material has good compatibility；It is not degradable and because constituting indane ring structure, therefore there is good thermal stability,
Ageing resistance, mobility can cook anti-friction agent, reduce piston with the frictional force between cylinder wall, and instantaneous fuel economy acts on,
Good operating condition is kept, is prolonged the service life.
The technical principle of the embodiment of the present invention is as follows：
Burning is the exothermic reaction between the oxygen in a kind of fuel oil and air.If fuel oil is not atomized well before ignition
Or oxygen needed for burning is inadequate, will lead to incomplete combustion.When burning complete, the hydrocarbon in fuel oil passes through several with oxygen
Step chemical reaction is oxidized to hydrocarbon and hydrocarbon.
Hydrocarbon+O2---CO+OH (fast reaction)
CO+OH---CO2+H2O (slow reaction)
It will increase carbon monoxide, sulfur dioxide and nitric oxide production discharge when incomplete combustion.The carbon monoxide of assembly
It can be accumulated in combustion chamber and make oxidation reaction incomplete, so as to cause smoldering, generating cigarette ash and other problems.The oil of deposition
Cigarette and cigarette ash will lead to electronic spark advance, and oil circuit pollution and exhaust system are obstructed.
Oil circuit cleaning agent proposed by the present invention contains α-MS cyclodimerization body activating agent, and it is anti-to accelerate rapidly carbon monoxide
It should be at the slow oxidation process of carbon dioxide.
CO+OH+ activating agent --- reactive intermediates (fast reaction) reactive intermediates --- CO2+H2O
It can thus be seen that fuel system multiple-effect non-dismounting cleaning agent proposed by the present invention can make fuel oil that more complete oxygen occur
Change process.This not only makes engine obtain more effective energy, but also can also greatly reduce carbon monoxide and carbon in tail gas
Remaining carbon distribution in hydrogen compound and combustion chamber and exhaust system.
Fuel oil dirt：There are many reason of booty on fuel oil spray head is formed, and (inferior quality, the content of wax, engine adjustment are improper
Deng) these booties will affect the spray pattern that fuel oil enters combustion chamber.Therefore lead to non-uniform burning.This result will lead to
Increase in tail gas for the hydrocarbon and carbon monoxide of burning, to seize up, oil consumption increases engine, and power is reduced.
The polyisobutylene amine contained in fuel system cleaning agent proposed by the present invention can be reduced with polyetheramine dispersant
The assembly of paraffin particles, various problems caused by eliminating because of dirt.Meanwhile efficient cleaning action is able to maintain sprayer cleaning, promotees
Good into fuel-oil atmozation, burning is complete, to largely reduce in tail gas as the hydrocarbon of burning and the content of carbon monoxide.
Wherein, the mechanism of action of several main components is as follows：

In the process of running, intake valve is easy to produce deposit to petrol engine, and intake valve is caused viscous valve, absorption combustion occur
Oil, phenomena such as being not closed completely with valve ablation；Atomizer generates deposit, it may appear that the bad shape such as fuel flow loss and atomization
Condition, easily causes that engine cold-start is difficult, it is out of strength to accelerate, is short of power, the deterioration of oil consumption raising and exhaust emissions.By to gasoline
Middle addition gasoline cleaning agent can thoroughly avoid this problem.
Nonyl phenol polyethers amine, isobutene alkyl phenol alkylamine are oil soluble surfactant, can be obtained after being added in gasoline
With uniform dissolution, structure is made of polar group and non-polar group.Non-polar group ensures its in the oil good molten
Solution, polar group make it that can smoothly be adsorbed on the surface of metal and deposit, are formed " molecule barrier film ".Insatiable hunger in gasoline
It is easy to be condensed and be precipitated at high temperature with hydrocarbon and heavy nitrogen/sulphur compound, is attached to metal surface and forms deposit, " molecule resistance
Diaphragm " can prevent the attachment of deposit intermediate in the dense proper alignment of metal surface, be allowed to can not form deposit.It is another
Its oil-soluble and dispersibility can be improved in the absorption of deposit surface in aspect, surfactant, makes it gradually entrained by fuel oil,
It eventually enters into combustion chamber and participates in burning.Amine is to belong to alkalinity, it can aoxidize the acid generated with neutral lubrication oil, prevents it further
Condensation, thus heavy polymer is reduced, while corrosion of these acidic materials to engine components can also be prevented.
2,1,1,3-trimethyl-3-phenyl indan effect
α-MS cyclodimerization body is allowed to and many macromolecule materials since the methyl in molecular structure makes phenyl ring generate induced dipole
Material has good compatibility；And because constituting indane ring structure, not degradable, thermal stability and antioxygenic property are good, can
For special occasions.The magnetic resonance for adding hydrogen Oxygenation to generate with automobilism occurs, gradually penetrates oil molecule, interrupts gasoline
Strand.Under the action of α-MS cyclodimerization body activating agent, hydrogen-oxygen energy is largely supplemented to engine chamber, reaches abundant
Atomizing keeps engine charge, compression, work done, exhaust four stroke circulation more thoroughly more perfect, makes no clean-burning vapour
Oily full combustion.It should be noted that：The concentration of α-MS cyclodimerization body has large effect to using effect, it is proposed that according to the country
Fuel oil quality, concentration is slightly denseer, to obtain optimum efficiency.
