Can the three way catalytic converter cleaning equipment clean diesel vehicles?

The three-way catalytic converter for automobiles can be cleaned with hydrochloric acid. Non-dismantling cleaning, that is, by "hanging bottles" or adding cleaning agent to the fuel tank, the specific method of "hanging bottles":

1. Start the engine, extinguish the engine after the water temperature is normal, pour the product into the special equipment, and connect the equipment output joint with the vacuum tube.

2. Start the engine, control the speed at about 2000 rpm, open the flow control valve, and slowly drip the product into the air inlet for about 30 minutes;

3. After cleaning, keep the engine speed for 3-5 minutes to drain the residual liquid.

Extended information: The cleaning method of the three-way catalytic converter is, the first one is to remove it for cleaning; the second is to use chemical products to dissolve and remove; The third is direct replacement. It is mainly a honeycomb substance composed of a combination of many rare metals, and its main function is to purify the air.

The three-way catalytic converter is a purification device of the engine, and its normal operation determines the fuel consumption, power, emissions and other working conditions of the engine.

If it gets clogged or malfunctions, then the first thing to do is that the exhaust emissions will exceed the standard. In addition, it will also affect the performance of the engine, which is often manifested as increased fuel consumption, weak acceleration, abnormal sound of exhaust pipes, and unpleasant exhaust smell.

Explain how to clean the three-way catalytic converter.

Hello, you can't clean it yourself, and even some repair shops don't have this equipment. It is recommended to find a repair shop that has the equipment cleaned. I hope my answer can help you. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello: Wash with dilute hydrochloric acid. Have a nice ride! [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

The answer is generally recognized by car owners or repair shops is to use oxalic acid solution for cleaning, and the effect is also obvious, but this method needs to disassemble the three-way catalytic device, and there are certain requirements for the exchange ratio and soaking time of oxalic acid solution, and the internal structure will be damaged if it is not used properly. The second is dismantle-free cleaning, that is, by "hanging the bottle" or adding cleaning agent to the fuel tank, but the effect of this method is not as obvious as the first one, and it is suitable for the use of three-way catalytic slight blockage.

Attached: The specific method of cleaning the three-way catalysis by hanging the bottle:

1. Start the engine and extinguish the engine when the water temperature is normal;

2. Pour this product into the special equipment and connect the output joint of the equipment with the vacuum tube;

3. Start the engine, control the speed at about 2000 rpm, open the flow control valve, and slowly drip the product into the air intake for about 30 minutes;

4. After cleaning, keep the engine speed for 3-5 minutes to discharge the residual liquid.

Three-way catalytic converter blockage and blockage fault performance:

1. The first stage is the slight blockage stage. At this stage, the chemical complex is adsorbed on the surface of the catalyst. It is only manifested as a decrease in the exhaust gas purification function. Exhaust emissions exceed the standard.

2. The second stage is the moderate blockage stage. Chemical complexes have accumulated on the surface of the catalyst to a certain extent, at which point the exhaust backpressure increases. Fuel consumption increases and power decreases.

3. The third stage is the stage of severe blockage. Due to severe clogging, the operating temperature of the "three-way catalytic converter" increases. A high-temperature sintering jam is formed at the front end of the three-way catalytic converter.

Can be washed.

Detection and judgment of the blockage method of the three-way catalytic system:

The three-way catalytic converter is affected by its own harsh working environment and its conversion performance characteristics, and there will be various faults in the process of use. For example, due to the blockage of the three-way catalytic converter, the engine power decreases, the flameout or the start is difficult, and the exhaust gas exceeds the standard, which is likely to interfere with our fault judgment.

1.Check whether the voltage of the front and rear oxygen sensors of the three-way catalytic converter is consistent. If it is consistent, it means that the three-way catalytic converter is damaged, that is, it is blocked or the three-way is burned because of the engine misfire.

2.Reach over to the exhaust pipe to see if you can feel the airflow, if you can't, it's blocked.

3.Take off the air filter. Step on the gas pedal on the spot. When I look at it, black smoke comes out of the air filter.

4.The temperature difference between the front and back of the thermosensitive three-way catalytic converter is used to determine whether it is blocked.

5.The maximum speed was not reached during the test drive, and the acceleration was poor.

Answer: The three-way catalytic converter can be cleaned, with the growth of the car's use time, it will breed a lot of carbon deposits, including throttle carbon deposits, fuel injectors, and three-way catalytic converters will have carbon deposits, if not cleaned, it will cause some failures of the car, affecting the performance, and regular cleaning is to restore the performance of the car.

It is recommended that you try Carbon King three-way catalytic deep cleaning agent, which is used to strongly remove carbon, sulfur, phosphorus, manganese, iron, and zinc compounds on the surface of the three-way catalytic converter, prevent clogging, dredge the microporous channels of the catalytic converter, restore the activity of the catalytic converter, and prolong the service life.

Explain how to clean the three-way catalytic converter.

The advantage of completely disassembling and cleaning, and cleaning the hanging bottle is that it is convenient and fast, without disassembling the exhaust pipe. However, in many cases, the effect of this cleaning method is not ideal, and the three-way catalytic converter needs to be completely disassembled for cleaning. This method is more thorough, after dismantling the cleaning agent after flushing, open the spray gun can filled with water and spray more than three bottles in a row, it is best to use the high-pressure spray gun of the cleaning car to clean the grille to ensure that the mud between the gaps between the ternary grilles can flow out completely.

Rinse with a hose and then use high-pressure gas.

After the <> is cleaned, the car significantly improves the fuel atomization performance, improves the combustion efficiency, reduces fuel consumption, and saves fuel by 5-20%; Improve the low-temperature cold start ability and reduce noise; Improve the power performance, prolong the service life of the engine and the three-way catalytic converter, so that the vehicle can be properly maintained. First of all, it is necessary to deal with the fuel injector, and the oil circuit can be cleaned, so it is recommended to use the fuel mate fuel injector jargon before testing, then it is necessary to change the element catalysis**.

There are many reasons why the exhaust gas is not up to standard, there will be problems with the nitrogen and oxygen sensor, and the urea will be unqualified, and the three-way catalysis will not cure the symptoms, if the particulate matter is unqualified, it is related to the particle trap (the diesel car is equipped with a particle trap, and the gasoline vehicle is called a three-way catalytic converter), and the particle trap may need to be cleaned or replaced. Direct cleaning, we are easy to clean the blockage material on the surface to the inside of our three-way catalysis, but it will cause our three-way catalytic interior to be blocked again, so many times we use a no-dismantling cleaning machine after the three-way catalytic blockage is serious.

The reaction will adhere to the surface of the three-way catalyst sulfur, phosphorus chemical complex, gasoline combustion incomplete products, into two, if the three-way catalytic converter is found to be damaged, the owner is better to replace it, and it is best to buy the original, because many so-called auxiliary factories say that the good thing is counterfeit, it is likely to affect your future car review results. You can't toss around like a teacup or bowl. The best way to clean is according to its working principle, because it works at high temperatures, and if there are debris residues, especially carbon deposits, nothing can be washed, including strong acids and alkalis, and organic solvents.

Explain how to clean the three-way catalytic converter.

Start the engine, when the coolant is normal, turn it off immediately, and then pour in the cleaning agent specially for cleaning the three-way catalytic converter, start the engine immediately, maintain it to 2,000 rpm, and then wait for the cleaning agent to come out slowly.

Cleaning this three-way catalytic converter must be carried out in a professional auto repair shop, don't blindly clean it yourself, and the damage outweighs the loss.

Whether it is a diesel vehicle or a gasoline vehicle, the three-way catalytic converter should be disassembled before it can be cleaned. And you need to use a professional cleaner to clean it.

It must be cleaned with a special potion, otherwise the part will be damaged, which will cause more danger.

What is the role of three-way catalysis in automobiles. Why do many second-hand car dealers have to do it.

At present, there are two mainstream cleaning methods of three-way catalysis: additive cleaning and hanging bottle cleaning, whether it is additive cleaning or hanging bottle cleaning, the cleaning effect of the three-way catalytic converter is not very high. If you want to clean the three-way catalytic converter more thoroughly, you can only disassemble and clean it, but because this method is relatively troublesome, time-consuming and laborious, it is generally not available in 4S shops and repair shops.

Although the store does not provide dismantling and washing services, we can still DIY the operation by ourselves, and the specific operation steps are as follows:

1. First of all, use a lift to lift the vehicle and completely disassemble the three-way catalytic converter.

2. Use oxalic acid solution (1:10 ratio to water) to soak and clean the three-way catalytic converter, and then rinse the three-way catalytic converter with clean water.

3. Load the cleaned three-way catalytic converter back into the vehicle and start the test run.

Additive cleaning:

Additive cleaning is to add a special three-way catalytic cleaning agent to the fuel tank, and when the vehicle is started, the cleaning agent will enter the combustion chamber with the gasoline, and finally be discharged through the exhaust pipe and exhaust gas, and when it passes through the three-way catalytic converter, the cleaning agent will have a certain cleaning effect on it.

The advantages of this method: affordable and easy to operate; Disadvantages: The cleaning effect is very limited.

Hanging bottle cleaning: Hanging bottle is currently the most mainstream, and it is also a cleaning method strongly promoted by 4S shops and repair shops. In this method, a hose is connected to the engine vacuum pipe, and the cleaning agent in the hanging bottle is sucked into the engine with the help of negative pressure in the hollow pipe, and the three-way catalytic converter is cleaned when it is discharged with the exhaust pipe.

Advantages of this method: easy to use, good cleaning ability; Cons: Expensive.

As one of the most important components in the exhaust purification system of gasoline vehicles, the three-way catalytic converter undertakes the catalytic reduction of harmful gases such as carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides NOx in the exhaust gas: the three main harmful gases of CO, HC and NOX are catalytically reduced into non-toxic and harmless water (HO), carbon dioxide (CO2), nitrogen (N2) and oxygen (O2) discharge.

In the process of long-term use of the three-way catalytic converter, there is no lack of carbon deposits and other substances attached to the porous ceramic carrier in the vehicle exhaust gas, and in the long run, it may be blocked.

The three-way catalytic converter for automobiles can be cleaned with hydrochloric acid. No disassembly and cleaning, that is, by "hanging the bottle" or adding cleaning agent to the fuel tank, the specific method of "hanging the bottle": 1. Start the engine, extinguish the engine after the water temperature is normal, pour the product into the special equipment, and connect the output joint of the equipment with the vacuum tube.

2. Start the engine, control the speed at about 2000 rpm, open the flow control valve, and slowly drip the product into the intake tract for about 30 times
