Description

Combustion catalyst for internal combustion engines {EXAUST GAS ABATEMENT MATERIALS FOR INTERNAL COMBUSTION ENGINE}

The present invention relates to a combustion catalyst for internal combustion engines, and more specifically, to provide a combustion catalyst capable of promoting combustion in the engine of an internal combustion engine, and to adjust the catalyst injection amount and air injection amount for each vehicle when injecting the combustion catalyst. It relates to a combustion catalyst for an internal combustion engine capable of providing an injection device.

In general, the gas emitted by an internal combustion engine is called exhaust gas, and contains countless harmful substances such as carbon dioxide, carbon monoxide, hydrocarbons, sulfur oxides, hydrogen sulfide, nitrogen oxides, and ammonia. Since carbon monoxide is created due to a lack of oxygen during combustion, it will not be generated if the mixture is diluted to more than 148%, which is the stoichiometric air fuel ratio of a gasoline engine (the ratio of air and gasoline that the mixture completely burns). The generation of hydrocarbons is minimal, but if it is diluted beyond the theoretical air-fuel ratio, the propagation of the flame stops, causing incomplete combustion, and carbon monoxide increases.

Nitrogen oxides are created when oxygen and nitrogen in the air react at high temperatures, so they reach a maximum around the stoichiometric air-fuel ratio.

The internal combustion engine confines a mixture of fuel and air in a sealed cylinder, compresses and ignites it, and rapidly burns the carbon in the fuel.

After combustion, the gas is discharged to the outside and a fresh mixture is brought in again, and the gas that is discharged to the outside is the exhaust gas.

Among the internal combustion engines, most of the exhaust gases combusted and emitted from engines such as gasoline or diesel used in automobiles.

The exhaust gases emitted from these vehicles contain components that pollute the air and are harmful to the body, and have become a social problem due to new pollution.

As the problems of environmental pollution and resource depletion emerge as described above, fuel efficiency improvement agents such as smoke reduction agents or smoke reduction devices are continuously being developed.

However, even recently developed smoke reduction compositions only reduce smoke by 30 to 40% and improve fuel efficiency by only 5 to 10%. Although vehicles with improved fuel efficiency are being developed, the progress of environmental pollution and resource depletion is significantly faster, and the development of compositions with excellent smoke reduction effects is in progress.

Previously, technology related to combustion promotion and smoke reduction compositions has been disclosed in Korea Intellectual Property Office Registered Patent Publication Nos. 0690553, 1716174, or Publication No. 2017-0110137.

However, conventional combustion promotion and smoke reduction compositions had the following problems.

(1) Since the catalyst composition must be supplied in large quantities to be effective, it is consumed very quickly and must be replaced frequently.

(2) It is very inconvenient because installation is complicated when installed on the intake or exhaust side, and a very complicated process is required when replenishing.

(3) Since the customized input amount cannot be adjusted for each vehicle, the efficiency varies depending on the type of vehicle.

In order to solve the above problems, the present invention includes a basic powder prepared by stirring and mixing white clay, lacquerware, tourmaline, zeolite, and pozzolan in the same weight ratio; Rare earth metal water prepared by dissolving 1 to 50 g of citric acid, ruthenium, and magnesium hydroxide per liter of water; Activated clay water, which prepares a liquid floating at the top over time after mixing white clay powder in water; Rock powder water is prepared by mixing 300 g of shungite powder, 200 g of nephrite powder, and 400 g of olivine powder in equal weight per liter of water, adding them to water and stirring them, and then preparing a liquid floating on the top after the powder settles; Prepare a polyvinyl solution formed by mixing 200 g of polyvinyl alcohol (PVA) and 30 g of silver nano powder per liter of water,

For each liter of the above main material, 1 kg of basic powder and 1 liter of activated clay water are stirred and then allowed to settle at room temperature for 30 days to completely settle in a stationary state to form a secondary material.

It is characterized in that 300 g of the primary material and 500 g of the secondary material are mixed with 1 liter of the activated clay water, stirred, and aged at room temperature for 30 days.

According to the combustion catalyst for an internal combustion engine formed in a preferred embodiment of the present invention, the following effects occur.

(1) In order to prevent the rapid diffusion of combustion catalysts, polyvinyl liquid is used, so even a small amount can have the effect of a combustion catalyst (gas phase) for a long time.

(2) It can be installed very simply because only the intake connection hose needs to be connected to the front end of the air filter.
