Problems solved by technology

CN101230298A discloses a gasoline detergent that can significantly reduce deposits in the combustion chamber of a gasoline engine. This patent uses a solution of polyetheramine and polyether. The detergency of polyetheramine alone is not strong, and a relatively large dose is required to achieve a certain level of cleanliness. cleanliness
CN101230297A discloses a gasoline detergent that can reduce deposits in the combustion chamber of a gasoline engine. This patent uses polyisobutenylamine and polyether as the main raw materials, and has certain detergency, but the cleaning function is not strong, and it is easy to cause combustion when used in large doses. increase in chamber deposits
[0004] In modern automobile technology, electronic fuel injection system (PFI) has completely replaced carburetor cars, and gasoline direct injection (GDI) technology is gradually becoming popular. The fuel injectors of these engines have small apertures and high operating temperatures. It is easy to be blocked by carbon deposits, causing problems such as poor atomization, poor oil supply, increased fuel consumption, and worsened emissions.
With the development of modern engine technology, the application of turbocharging and waste recirculation systems is becoming more and more extensive, the heat load of the engine is increasing, and the deposit problem of the engine intake valve is becoming more and more serious. The intake valve deposits cause The cylinder is not tightly sealed, resultin...

Abstract

The invention relates to a gasoline detergent with cleaning function and a preparation method thereof. Gasoline containing the detergent can clean deposits in an oil injection nozzle, an air inlet valve and a combustion chamber of a gasoline engine. The detergent comprises at least one type of high-activity polyetheramine, at least one type of high-activity polyisobutene amine, base oil serving as carrying oil, other solvent oil and functional agents such as an antioxidant, an anti-rusting agent, a preservative and a demulsifying agent. Specifically, the detergent comprises the following components in percentage by mass: 10 to 80 percent of polyetheramine, 5 to 20 percent of polyisobutene amine, 5 to 35 percent of carrying oil and 5 to 35 percent of solvent oil and other functional agents. After being added into commercially available motor gasoline according to the dosage of between 1,000 and 3,000 ppm, the detergent of the invention can suppress and clean the deposits of the oil injection nozzle, the air inlet valve and the combustion chamber of an oil-fired air inlet system of the gasoline engine. The motor gasoline containing the detergent of the invention can clean the deposits of the oil injection nozzle, the air inlet valve and the combustion chamber in which the deposits are generated.
