Wuling light, three way catalytic converter to launch 474, how much

Hello, the repair shop 350 to 400 dollars will do.

Wuling Hongguangof the original carThree-way catalytic converterThe market price is about 800 yuan.

The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system, which can convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide through oxidation and reduction.

Water and nitrogen. When the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of CO, HC and NOx, and promote it to carry out a certain oxidation-reduction chemical reaction.

Among them, CO is oxidized at high temperatures to become colorless and non-toxic carbon dioxide gas.

HC compounds are oxidized to water (H20) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. The three harmful gases become harmless gases, so that the exhaust gas of the car can be purified.

Working principle: three-way catalytic reactor.

Similar to a muffler. Its outer part is made of a double layer of stainless steel sheet to make a barrel. In a double-layer sheet interlayer is installed an insulating material - asbestos fiber felt. The inside is filled with a purifying agent in the middle of a mesh partition. The purification agent consists of a carrier and a catalyst.

The carrier is generally made of aluminum oxide.

It is made in the form of spherical, polygonal and mesh partitions. The purifying agent actually acts as a catalyst and is also known as a catalyst. The catalyst is made of platinum, rhodium, and palladium. Spraying one of these on the carrier constitutes a purifying agent.

The market price of the three-way catalytic converter of Wuling Hongguang original car is about 800 yuan, I hope mine can help you.

Wuling Hongguang S National VI, 2019, how much is the original three-way catalytic converter.

This auto part is not very expensive, you can buy it for about two hundred yuan.

ThisThree-way catalytic converterIt is relatively expensive, basically about 1500 to 2000 yuan. For this, it is recommended to go to the four S store to replace the original one.

Safety hazard: The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system, which can remove the automobile exhaust gas.

Harmful gases such as CO, HC and NOx are converted into harmless carbon dioxide through oxidation and reduction.

Water and nitrogen. Make a good code hole in the appropriate position of the exhaust pipe at the front end of the catalytic converter and connect a pressure gauge.

Start the engine at idle.

and 2500r min, respectively, the exhaust back pressure is measured, and if the exhaust back pressure does not exceed the limits specified by the engine, it indicates that the catalyst carrier is not blocked.

Hello, if the Wuling light van is replaced with a three-way catalytic converter, it is generally about 1500 yuan.

Sell more than 100 or 200 online, and the normal ** to the repair shop is three times, that is, five or six hundred yuan, the working hour is 150-200 yuan, and the normal price is 600 to 800 yuan, and the 4S shop is a dry yuan. If you know the car and understand the accessories, 180 yuan + 15o yuan labor a total of 330 yuan, if you have tools, you will be 200 yuan. If you don't understand anything, go to the 4S store and spend a lot of money.

Replace more than 200 three-way catalysis. If you want 1000 or 2000, it's not a regular repair shop, think about it, it's only 2200 for another engine, how much can a three-way catalysis cost? Is a three-way catalysis more expensive than an engine?

I changed it to say that it was 350 yuan from the original factory, I don't know if it's true or not, but I have passed the annual inspection after the annual inspection.

Three-way catalytic converterIn the first section of the car exhaust header bulge,The shape resembles a marching kettle. The three-way catalytic converter is installed in the exhaust system of the automobile, and it is an external purification device that is very important in the exhaust system.

There are two interpretations of the "ternary" in a three-way catalytic converter. One theory is that this catalytic converter can convert the three main harmful substances produced after the combustion of the engine into harmless substances at the same time, so it is called ternary.

The three main substances are:

CO (carbon monoxide.

HC (hydrocarbons), NOx (nitrogen oxides.

There is also a saying that because this catalytic converter lapat contains platinum (Pt), rhodium (Rh), and palladium (PD), it is called ternary.

These three kinds of *** can promote the three main harmful gases produced after the combustion of the cavity engine to react with each other, and finally produce harmless carbon dioxide.

Nitrogen dioxide, water.

The ** of the three-way catalytic converter is based on the brand and positioning of the vehicleAs well as the channels of product purchase and sales are different, their ** is not the same, but under normal circumstances, the ** of three-way catalysis is basically maintained above 1500.

Due to the counterfeit and shoddy three-way catalysis, not only can not meet the emission reduction standards of automobile exhaust, but may even cause a sharp increase in emission pollutants.

When the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of CO, HC and NOx, and promote it to carry out a certain oxidation-reduction chemical reaction, in which CO is oxidized to become colorless at high temperature.

Non-toxic carbon dioxide gas; HC compounds are oxidized to water (H20) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. The three harmful gases become harmless gases, so that the exhaust gas of the car can be purified.

How three-way catalysis works:

1. In normal three-way catalysis, the pores of the internal porous ceramics should be evenly arranged and the size should be consistent, and the porous ceramics should be clean and white.

2. The porous ceramics in the three-way catalysis are used as the carrier, and the assembly of the outer tank should be strong and firm, and there should be no loosening (even if it is slightly loose).

Precautions for three-way catalytic converters:

1. If there is mechanical damage, thermal sintering, and the mileage exceeds 200,000 kilometers, and the situation of lead poisoning, the cleaning effect is not large.

2. If the engine is turned off in the middle of cleaning, immediately disconnect the connecting hose between the engine and the equipment, and close the flow valve. Restart the engine and reconnect it after the idle speed is stable.

Hello friend. Like you, if you say three-way catalysis, if you buy the original factory. The three-way catalytic ** will be about 2,000 yuan, and friends will be more than 2,000 yuan.

If the national standard is used, if it can be inspected annually, this three-way catalysis is also more than 600 yuan. If you personally suggest it, you can buy a national standard, you don't need to buy this original factory, the original ** is too expensive.
