Description
[technical field]
The present invention relates to a kind of fuel oil additive and preparation method thereof, relate in particular to a kind of GDI engine energy-conserving and environment-protective carbon remover fuel oil additive and preparation method thereof that dewaters, belong to chemical technology field.
[background technology]
Aspect combustion engine energy-saving and green technology, GDI(gasoline in-cylinder direct-jet) engine is with its higher fuel efficiency, and lower gas exhausting property, is applied in various mainstream car design rapidly.Although GDI engine is more advanced, but owing to being subject to, fuel qualities is poor, lubricating oil use in the impact of each factor such as sulfur-bearing phosphorus antioxidant, urban road congestion, automobile travelled after for some time, inlet system, the firing system of engine still can produce colloid carbon deposit, in the oxygen sensor of exhaust system, ternary catalyzing unit, still can adhere to obstruction chemical complex, thereby cause the problems such as automobile fuel consumption increases, power declines, tail gas exceeds standard, therefore, after the certain mileage of running car, GDI engine is the same with PFI engine will clean maintenance.But because GDI engine and PFI engine fuel and blowdown system have larger difference, some problems below self existing in application, if do not note the rational operation and maintenance of vehicle (fuel qualities requires higher), more easily cause GDI prime the fuel system and discharge etc. to occur abnormal working order.GDI engine characteristics and problems is as follows:
1. adopted the combustion mode such as stratified combustion and homogeneous combustion at the GDI of use engine (as popular TFSI engine), oil thrower is different from PFI engine, require atomization quality to require higher, general Suo Te mean particle size (SMD) should not be greater than 25Lm, 90% fuel oil granularity (DV90) is no more than 45Lm, in order to keep suitable penetration degree, injection oil pressure should maintain between 4～13MPa simultaneously.The oil thrower of GDI engine is placed in cylinder, and injection oil pressure is low relatively, and spray orifice does not have self-cleaning ability, is easy to fouling, causes fuel charge minimizing, spray characteristics to degenerate, and then makes the burn deterioration of engine, affects power stage and the discharge of engine.
2.GDI prime the fuel system has adopted high-pressure pump (band oil pressure adjusting valve), and petrol-feed pump and oil thrower power requirement are high, and on market, the oilness of gasoline is poor, and the impurity such as water, sulphur are more, should improve by additive.
3.GDI petrol motor, in the time of ultra-lean burn, easily causes carbon distribution because high temperature lacks fire.The steam raising of fuel makes cylinder temperature on the low side in addition, and after igniting, flame weakens gradually in communication process, causes flame-outly, and gas mixture can not fully be burnt, and produces carbon distribution.
4. under medium and small load, the discharge of unburned carbon hydrogen (UBHC) is more, during because of employing stratified mixtures, easily causes extinguishing of Xiang Xi district of flame Cong Nong district, and rare air-fuel ratio working conditions causes cylinder temperature on the low side, is also unfavorable for the continuation oxidation subsequently of unburned carbon hydrogen.In addition easily cause GDI engine particulate emission to have more increase than traditional intake port injection petrol motor in the situation that of underload, transient running and cold start-up, therefore easily make ternary catalyzing unit and oxygen pass the emission control systems such as device and lost efficacy.
Gasoline is very large on motor performance impact, and the technological lag that fuel oil is produced is in the speed of development of automobile, and domestic gasoline dope research also far lags behind developed country.Be subject to the restriction of outdated equipment and state of the art, China is current more than 80% is catalytic gasoline, and olefin(e) centent is higher.Fuel oil specification current index in the world's is lower than 10% (alkene), and China is up to 35%.
The maintenance such as gasoline dope and engine cleansing agent is various in style, and purposes is also not quite similar, according to applied links, and the additive that the additive, transport that can divide the application of Oil Production process and stock's link are used, the additive of automobile terminal user use.In the maintenance product using at user vehicle, on market, the clean-out system such as the cleaning oil thrower of simple function, cylinder or valve carbon distribution, ternary catalyzing unit is more.Mostly marketable gasolines additive is by the packing of clean kept type product, needs each interpolation to play certain effect of keeping a public place clean to vehicle; But the carbon distribution that firing system has been produced, is difficult to effectively clean.The technical solution of some additive, is that for PFI engine, even carburettor class vehicle was designed originally, and improper use can increase the combustion chamber deposit (CCD) of GDI engine, affects engine normal service life.From entirety, the additive research of the raising gasoline performance using with petrochemical industry fuel oil production process is more, for automobile terminal user's engine maintenance articles for use, mainly for the work of PFI engine and constructional feature and develop, the product research that is applied to GDI engine is less.
