The multi-function gasoline additive composition comprises (A) a large number of diluent solvent, (B) carrying oil, (C) at least one detergent and/or an anti-deposition agent, (D) at least one antioxidant and/or a metal purifying agent, (E) at least one an anti-rust agent and (F) at least one demulsifying agent. The additive composition is characterized in that the cleanness of fuel air-intake systems, such as a carburetor, a hole type fuel injector, an intake valve, etc. can be kept when the additive composition is added into gasoline to be used for an engine, so the service life or the maintenance period of additive composition can be prolonged, and the fuel intake systems can be guaranteed to effectively work synchronously; thereby, the fuel is obviously saved and the contents of exhaust pollutants are obviously reduced.
Description
The composite additive for gasoline that the present invention relates to is mainly used in the Fuel Petroleum that the automobile spark plug spark ignition engine is used, and to improve its performance, belongs to field of fuel additive technology.
As everyone knows, fuel saving and minimizing exhaust contaminant are the strategic objectives that whole world automotive industry is improved engine design always.The eighties, the port fuel injectors (PFI) that the car petrol engine of external industrially developed country is extensive use of electronic calculator control replaces original vaporizer, state in realization and obtained major progress on the target, but, hydro carbons in the Fuel Petroleum oxidation generation paint film, carbon deposits under the environment for use condition influence the vaporizer of motor spirit inlet system, or the problem of normal runnings such as port fuel injectors, intake valve is also more outstanding.Thereby make gasoline cleaning agent and anti-deposition agent be used widely and develop.The U.S. is defined in whole gasoline of domestic sale, from January 1 nineteen ninety-five, must add purification agent and anti-deposition agent; In Britain, white gasoline is obtaining before Automobile Associations confirms, should have the vaporizer of making, fuel injector and intake valve and keep clean and eliminate sedimental performance; Also there is similar requirement in France.The Car Manufacturers Institute (CMI) of US and European has considered that also gasoline product increases the technical requirements of detergency aspect at present.
China's late nineteen eighties is to the external car of the nineties import, and major part has adopted the port fuel injectors of electronic calculator control for prime the fuel system.The car of new generation of domestic main automobile manufacturing company production and light truck all adopt and maybe will adopt port fuel injectors for prime the fuel system.Santana's 2000 type cars as Shanghai Volkswagen, Audi's 100 type 2.6E cars that First Auto Group is produced, the lucky spectrum of the Cherokee of new generation car that the luxury bearing-Citroen car of car wind motor corporation and the joint production of French PSA group and Beijing automobile factory produce etc.It should be noted that in China's gasoline product, the catalytically cracked gasoline component accounts for about 70%.Olefin content in gasoline is more much higher than external gasoline.Therefore the tendency of the gasoline of China oxidation generation colloid, paint film and carbon deposits under the environment for use condition is more serious.Particularly after 2000, China will use in most of city the white gasoline more than No. 90, and the detergency problem of gasoline will be more outstanding.Hence one can see that, and gasoline cleaning agent and anti-deposition agent also have application promise in clinical practice in China.
Therefore, the objective of the invention is: a kind of composite additive for gasoline is provided,, can satisfy vaporizer is housed, or the port fuel injectors engine is to the requirement of gasoline cleanliness by adjusting ratio and the composition consumption between each component in the composition.Gasoline is had keep cleaning such as vaporizer, fuel injector and intake valve in the motor spirit inlet system and remove sedimental ability.
Because the envrionment temperature of spark ignitor formula engine vaporizer, fuel injector, intake valve and combustion chamber is different.The present invention is to each components selection in the composite additive for gasoline, should consider the characteristic functions excellence of each component, consider that again they have thermostability preferably at the higher position of intake valve equitemperature, and after entering combustion chambers burn with fuel, reduce at the combustion chamber internal surface as far as possible and form settling, avoid the generation adverse influence.To emphasize to consider that as diluting solvent each component is easily dissolved in the compositions of additives, be suitably employing dimethylbenzene; Carry oil and will help to be insoluble in the components dissolved of solvent or gasoline.But consider to reduce at combustion chamber internal surface formation settling after it enters combustion chambers burn with fuel as far as possible.Therefore should select aromaticity content less, paraffinic base lighting end mineral oil that hydrogen richness is higher and the less polyisobutene of molecular weight; Other molecular weight ratio solvent or the big binder component of petrol molecule amount, except that considering their self character function excellences,, hydrogeneous higher as one of principle of selecting also no aromatic ring structure.Should especially consider also that for the selection of purification agent and anti-deposition agent they are not only in the fuel injector of temperature lower (about 100 ℃) performance better action, and good heat-resistant quality, the effect that continues to bring into play are arranged at the intake valve of temperature higher (more than 180 ℃).To limit their content in composition to other relatively poor component of heat-resistant quality.
In case of necessity, also need add an amount of deicing agent in the composition.
