Description
Technical Field
The invention relates to the technical field of gasoline additives, in particular to a composition for removing deposits in an engine fuel oil circuit.
Background
With the increasing strictness of environmental regulations, how to reduce vehicle emissions becomes a focus of attention of all parties. Various large automobile manufacturers have been able to meet this demand by developing new engine technologies and exhaust gas aftertreatment technologies when designing and producing automobiles. However, since the vehicle gasoline (including alcohol gasoline) contains unstable substances, oxidation and polymerization can occur during the normal use of the vehicle, so that deposits such as colloid and carbon deposition are formed at the oil passage, the fuel nozzle, the air intake valve, the combustion chamber and the like of the engine, the normal operation of the vehicle is affected, and the problems of vehicle shaking, power reduction, fuel consumption, emission increase and the like are caused.
In order to solve the problems, the common proposal comprises adding a gasoline detergent into the gasoline, and cleaning an oil path by using the gasoline additive for a long time; or periodically using a large amount of deposit cleaning agent in gasoline to rapidly clean the deposits.
In Chinese patent CN201010517664, a gasoline detergent prepared by using aromatic amine polyoxypropylene ether is introduced, and when the gasoline detergent prepared by using the aromatic amine polyoxypropylene ether as a main component is used in gasoline, the generation of deposits in a fuel intake system of a gasoline engine can be obviously reduced.
In Chinese patent CN201010517654, a gasoline detergent prepared by using fatty amine polyoxypropylene ether is introduced, and when the gasoline detergent prepared by using the fatty amine polyoxypropylene ether as a main component is used in gasoline, the generation of deposits in a fuel intake system of a gasoline engine can be obviously reduced.
In chinese patent CN200710152388, a gasoline detergent capable of significantly reducing the deposits in the combustion chamber of a gasoline engine is introduced, which comprises a polyether amine with high surface activity, a polyether carrier liquid with excellent oil solubility, and a cosolvent, an antioxidant, an antirust agent, a preservative and a demulsifier functional agent thereof.
The patent CN201010274722.8 discloses a gasoline detergent with a cleaning function and a preparation method thereof, wherein the gasoline detergent comprises polyetheramine, polyisobutylene amine, carrying oil, solvent oil, an antioxidant and other auxiliary agents, and provides an engine deposit cleaning function.
The compositions obtained in these patents function primarily to clean and inhibit deposits from the engine's oil supply system and, under certain conditions, to reduce the amount of deposits in the engine's combustion chamber. However, with the development of alternative energy sources in recent years, it is required to use additive products that can be used for alcohol gasoline. The products of the patents have the problem of solubility in part of oil products when the adding amount of the products in the alcohol gasoline is larger. In addition, a large number of users exist in the market, and due to the fact that the users are convenient to use, the users hope that the deposits in the oil way can be quickly cleaned only through one-time adding and using, in the prior art, a large number of gasoline cleaning agents capable of achieving quick cleaning through one-time adding are achieved, and even if the gasoline cleaning agents can be quickly cleaned, the cleaned deposits are difficult to discharge along with fuel combustion in a short period in the daily running process of a vehicle, and the deposits in a combustion chamber can be increased in a certain period.
