Description
Technical field
The invention belongs to fuel oil fields, and in particular to a kind of preparation method of fuel oil additive.
Background technology
Gasoline and diesel oil etc. are the common liquid fuels for internal combustion engine.The work temperature of the fuel engines intake valve of automobile
Degree is about 200 ~ 300 DEG C, under this temperature condition, fuel oil（Particularly gasoline）In the alkene that contains, may be because of it
It is unstable and generate oxidation, generate gelatinous carbon distribution and be attached to the intake valve back side；Fuel oil（Particularly gasoline）In the virtue that contains
Hydrocarbon through burning generation carbon distribution and may deposit in the combustion chamber.It, can when the carbon distribution total amount increase of fuel engines combustion chamber
It is able to can increase the compression ratio of fuel engines, and not easy heat radiation, gas temperature liter when ending so as to cause burning interior compression
Height, OR Octane Requirements increase, the machine being also possible to when serious between the top land and cylinder cap that can increase fuel engines combustion chamber
The phenomenon that tool interferes, generation " carbon engine knock ", causes engine consumption to increase.After fuel oil additive is added in gasoline, can into
The gas handling system surface of air valve forms layer protective layer, prevents from generating a large amount of deposition in engine interior especially gas handling system
Object makes the engine of automobile keep cleaning during entire use.The main function of fuel oil additive is exactly to prevent fuel oil from firing
The carbon distribution generated after burning is attached to engine surface, can effective decarbonizing, promoted power, save fuel oil, reduce noise, prevent
Engine failure caused by fuel oil.
When engine operates, atomizer temperature is at 100 DEG C or so, and intake valve temperature is between 200 ~ 300 DEG C.Such
At a temperature of, the labile element in fuel oil easily generates oxidative dimerization, generates colloid and carbon distribution, be deposited in intake valve and
On atomizer, advanced high blower engine and the engine using GDI fuel direct injection technologies are more prone to carbon distribution.It is deposited in
Deposit on intake valve can cause inlet channel sectional area to reduce, and intake efficiency reduces, and power drop can make valve when serious
Door slow movement, is not closed completely.Atomizer carbon distribution can make oil spout not smooth, and fuel-oil atmozation quality declines, and fuel oil is caused to enter burning
Behind room, it is difficult to which completely burned causes engine start difficult, and unstable idle speed and oil consumption increase, and exhaust emissions deteriorates, especially
In winter, these situations are more obvious.Traditional solution is cleaned after engine is disassembled, not only time-consuming, heavier
What is wanted is that advanced supercharging technology and GDI technologies make engine more accurate, and many subsequent ask may be brought by disassembling cleaning
Topic, thus can in order to avoid the fuel system protective agent of demolition clean is the generally acknowledged new development trend in the whole world, Europe and the U.S. into
For mainstream.
Fuel oil additive is generally selected containing peroxide such as hydrogen peroxide or ketone peroxide at present, can certain journey
Decarbonizing on degree.It is that the hole of carbon distribution is pierced by very strong surface-active to clean principle, destroys its structure, and to these
Soot particle is split encirclement, gradually these soot particles is dissolved down from metal surface, the high-temp combustion together with fuel oil
It is discharged afterwards by tail gas.But fuel oil additive contains peroxide, easily causes machine surface and is corroded and existing
Fuel oil additive containing substances such as sulphur, phosphorus, causes environment pollution mostly.Therefore, a kind of environment amenable fuel oil is produced
Additive is very urgent.
