Problems solved by technology

[0003] There are few types of special cleaning agents for EFI throttle cleaning in China. In the past, carburetor cleaning agents were generally used to clean the throttle valves, which easily caused corrosion of throttle parts. At present, some maintenance personnel in the automobile maintenance industry still use carburetor cleaning agents
Although some solvent-based throttle cleaners on the market overcome the disadvantages of carburetor cleaners being corrosive to parts, they pose potential dangers to storage, transportation and use due to the use of flammable and explosive propellants sex
There are also some special cleaning agents for throttle valves that are water-based cleaning agents. If they are not completely dried after cleaning, it is easy to cause corrosion of the engine intake system and affect the service life of the engine.

Abstract

The invention provides an aerosol throttle cleaning agent. The cleaning agent is composed of the following raw materials, by weight, 40-65 parts of aliphatic hydrocarbon solvent, 6-20 parts of ester solvent, 4-15 parts of ether solvent, 2-5 parts of cleaning dispersant, 0.05-3 parts of organosilicon surfactant, 0.05-1 part of antiwear agent, 8-15 parts of tetrafluoroethane and 0.5-2 parts of nitrogen. The provided cleaning agent has characteristics of strong decontamination capability, safety, environmental protection, stable performances and easy operation.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to an aerosol-type cleaning agent for cleaning automobile engine throttle valves. Background technique [0002] The throttle valve controls the amount of air entering the engine according to the load of the engine. It is an important part of the engine system of an EFI car. It is connected to the air filter at the top and the engine block at the bottom. Whether the acceleration of the car is flexible is closely related to the cleanliness of the throttle valve. When the car has unstable idling speed, poor acceleration, increased fuel consumption, and difficulty in starting, the throttle valve should be checked and cleaned. [0003] There are few types of special cleaning agents for EFI throttle cleaning in China. In the past, carburetor cleaning agents were generally used to clean the throttle valves, which easily caused corrosion of throttle parts. At present, some main...
