Description

FUEL CONVERTER OF VEHICLES USING PLATED CATALYST}

TECHNICAL FIELD The present invention relates to an improvement of a fuel converter for reducing exhaust gas and increasing engine power of a vehicle using a catalyst. More particularly, the present invention relates to a fuel converter of a vehicle, which enables the vehicle to reduce emissions significantly.

In vehicles, there has been a method of encouraging the complete combustion of fuel by incorporating secondary air into the fuel mixer, but there is a drawback that the power output of the engine cannot be improved.

As an example of solving this disadvantage, Korean Patent Publication No. 93-349, "Automobile Exhaust Gas Reduction and Power Increase Device Using Alloy Catalyst," changes the composition ratio of the vehicle fuel supplied by using an alloy catalyst. Disclosed is an apparatus for inducing complete combustion to increase exhaust gas output of an engine, that is, energy consumption efficiency.

In Korean Patent Publication No. 93-349, almost complete combustion rate is increased in the engine, so smoke is reduced by 10-20% than in a conventional automobile, and the combustion efficiency is increased, the load on the engine itself is reduced, and noise is about 10-30%. There is a reduction effect. In addition, the engine output is increased by increasing the combustion efficiency, so even if you press the accelerator less during operation, the speed is the same. Therefore, the fuel is saved as you step on the gas. It is reported to be reduced by about%.

However, the prior art, such as Korean Patent Publication No. 93-349, uses an alloy catalyst containing precious metals such as silver (Ag), platinum (Pt), gold (Au), and the like. In addition, fluctuations in the price of precious metals such as platinum, gold, and silver pose a threat to the production of related parts.

Therefore, if a device that achieves a much lower price than the alloy catalyst and obtains a far lower reduction rate than the existing 10-20% reduction rate to meet the low-carbon green growth that is in the global trend these days, it will receive great response from the consumer. You will get

In addition, the biggest culprit of air pollution in large cities is the emissions of automobiles. In Seoul, which represents Korea, gas emitted from automobiles accounts for 80-90% of the air pollution. Therefore, the reduction of automobile smoke in the city is very important to create a clean urban environment, clear skies, and pleasant air in the city. If a device is developed to improve and achieve a higher smoke reduction rate, it will be a national policy or local smoke. It can also be a great help in car management and enforcement.

Therefore, an object of the present invention is to use a much cheaper catalyst than using an alloy catalyst, the emission reduction rate of the vehicle is much higher than using an alloy catalyst, and to increase the engine output or improve fuel efficiency to be equal to or better than using an alloy catalyst. To provide a fuel converter of a vehicle using a plating catalyst.

The present invention for achieving the above object is obtained by forming a platinum plating catalyst, a gold plating catalyst, a silver plating catalyst, a tin catalyst in the form of a spring and a pin and then integrally assembled, the catalyst body in a tubular catalyst case It is mounted to configure a fuel converter, the fuel converter is installed in the supply pipe between the fuel tank of the vehicle and the engine,

It is a fuel converter of a vehicle using a plating catalyst characterized in that the composition of the surface area ratio is composed of 1 ~ 9% to convert the composition of the gasoline fuel to be contacted to reduce the soot smoke and improve fuel efficiency.

In addition, the present invention, after the platinum plating catalyst, golden plating catalyst, silver plating catalyst, tin catalyst formed in the form of a spring and fins to obtain a catalyst body integrally assembled, the catalyst body is mounted on a tubular catalyst case to constitute a fuel converter And, the fuel converter is installed in the supply pipe between the fuel tank of the vehicle and the engine,

It is much higher than using the engine, and the engine output and noise sensitivity are similar to those of using the alloy catalyst, and the fuel economy of the vehicle is also improved by 10-20%. In particular, when the fuel converter of the present invention is installed, the emission reduction rate of the vehicle compared to the conventional vehicle is about 50 to 90%, which is much higher than the emission reduction rate of 10 to 20% using the existing alloy catalyst, thereby drastically reducing the air pollution in large cities. It is expected to be able.

Tables 1 and 2 below show an example in which the fuel supplied from the vehicle is converted into dozens of components of the fuel by a chemical reaction while contacting the catalyst body 10 of the fuel converter 2 including the plating catalyst.

Table 1 is a table related to gasoline as fuel of an internal combustion engine, and Table 2 is a table related to diesel. In the case of LPG fuel, it was not attached as data because there was a difficulty in testing the conversion of the composition of the fuel as a test item.However, similar to gasoline and diesel, vehicle emissions were significantly reduced compared to before the fuel converter 2 was installed. The result was confirmed.

The test vehicle mentioned in Table 6 is a vehicle that runs about 4 years after shipment and has a mileage exceeding 200,000 km, but after the fuel converter 2 of the present invention is installed, it satisfactorily satisfies the acceptance criteria and has no vehicle emissions. It is shown.

As described above, the reduction rate of the exhaust gas of the vehicle equipped with the fuel converter 2 of the present invention is superior to 50 to 90% compared to the case where the fuel converter 2 is not installed, so that the atmosphere of a large city It is anticipated that pollution will be greatly reduced.

In addition, the present invention increases the engine output and vehicle fuel efficiency is also included or further increased to the existing alloy catalyst, which can be confirmed through the fuel efficiency improvement results as shown in Table 7 below before and after the fuel converter (2) of the present invention.

The test vehicle mentioned in Table 7 is a passenger vehicle using LPG for private taxi and the model is NEW EF Sonata LPG.

As can be seen in Table 7, when the fuel converter 2 according to the embodiment of the present invention is mounted, fuel economy is improved by about 10 to 20% compared to before the fuel converter 2 is mounted.
