The present invention relates to a kind of novel engine fuel dope, belong to field of fuel additive technology.Fuel dope proposed by the invention is made up of compositions such as detergent-dispersant additive, power-lift agent, antioxidative stabilizer, tensio-active agent, combustion-supporting promotor, sanitas, base solvent, fuel dope involved in the present invention can be applied to engines such as gasoline, diesel oil, thereby the efficiency of combustion that improves motor spirit is improved engine power performance, the pollutent that clean burning produces and clean the settling of oil circuit, combustion chamber plays the function of fuel-economizing, environmental protection, automobile maintenance.
Background technology
Although automotive engineering has had very big progress, Automobile Motor Design as much as possible improves firing system, to improve the efficiency of combustion of fuel, still fuel incomplete combustion in engine is still failed thoroughly to solve in total aspect, produces the phenomenon of settling and obnoxious flavour.
Fuel is multicomponent mixture as the composition of gasoline or diesel oil, and non-complete combustion of fuel can produce NO, NO
2, SO
2, SO
3Deng gas, these gases are deleterious, can pollute air.
Secondly, SO
3The moisture formation that produces with burning has corrosive mineral acid, and engine metal is produced corrosion, reduces engine life.
The 3rd, fuel composition carbonization meeting produces the carbonaceous deposits thing under non-complete combustion of fuel or the high temperature, this class settling reduces the duty of engine, influences motor efficiency attached to engine combustion chamber interior walls, in-line and exhaust line, makes the oil consumption increase cause waste.
Four, the material that comes from the additive of fuel at high temperature also can produce gelatinoid, hinders the perfect combustion of fuel.
At the problems referred to above, all there is a large amount of patents to propose different solutions both at home and abroad with document.
English Patent, Chinese application number 94108930.4, having proposed with kerosene is carrier, reduces non-complete combustion of fuel with aliphatic amide and Fatty Alcohol(C12-C14 and C12-C18) and produces NO, NO
2, SO
2, SO
3Deng the method for metallic corrosion in gas and the control additive, fuel carbonization settling is not handled but relate to.
Chinese patent, China's application number 200810002847.8, having proposed with mineral oil is carrier, eliminates the method for combustion deposit with compositions such as terpenes, alkylene glycol ether, acetone, binary methyl ester and ethoxylized nonylphenols, but does not relate to the processing to engine corrosion.
Japanese Patent, Chinese application number 90108990.7 has proposed to add in the fuel with the seawater extract, with incendivity and the efficiency of combustion of improving fuel, but does not relate to fuel deposits and engine corrosion processing.
United States Patent (USP), China's application number 200810179914.3, proposed to control effectively the method for sedimentary formation in intake valve, port fuel-injectors and the combustion chamber, do not improved the etch-proof processing of fuel combustion and efficiency of combustion and engine but relate to Mannich reaction products.
In sum, although the patent of having delivered or having applied for has proposed different imaginations and scheme from different angles to the improvement of fuel dope separately, but also need further to improve in this field, particularly, need be improved all sidedly the employed fuel dope performance of engine, novel fuel dope should have the settling that clean burning produces, obnoxious flavour, prevent from engine is produced corrosion, improve fuel combustion efficiency simultaneously, play comprehensive effect of energy-saving and environmental protection, maintenance engine.
The fuel dope that the present invention proposes has solved the problems referred to above comprehensively.
