What is the difference between Xiongchuang automobile exhaust comprehensive treatment system and thr

Hello, this one is different, mainly in the way the chemical reaction takes place.

Hello, three-way catalysis is only one measure for tail gas pollution emission control.

One is the system, the other is the product, and the two need to be combined.

Let's first understand what is the role of the three-way catalytic converter of the vehicle: the role of the three-way catalytic converter: the three-way catalytic converter for purifying exhaust gas is the most important external purification device installed in the automobile exhaust system, which can convert harmful gases such as CO, HC and NOx discharged from the automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction.

This is because the catalytic converter converts the three main hazardous substances in the exhaust gas into harmless substances at the same time. With the increasingly stringent requirements for environmental protection, more and more cars are equipped with exhaust gas catalytic converters and oxygen sensor devices. It is installed in the engine exhaust pipe, through the redox reaction, carbon dioxide and nitrogen, so it is also called the ternary (efficiency) catalytic converter.

The common failure of three-way catalysis is that the internal grid is blocked, and the exhaust of the engine is not smooth, so the fuel consumption will increase and the power will decrease. Causes: It may be caused by the aging and damage of the materials inside the three-way catalysis after a long period of use.

Another fault is the damage of the three-way catalytic process, which leads to the damage of the three-way catalysis. Causes: The life of the three-way catalysis is up to the point of use, resulting in damage, and the three-way catalysis is damaged by external impact.

The occurrence of the above two faults will cause the engine fault to light up, and the fault code is generally a three-way catalytic performance failure. The vehicle will have an increase in fuel consumption and a decrease in power failure. Long-term failure to clean the three-way catalytic over-dirt will cause the engine failure light to light up.

Power decreases, fuel consumption increases. Causes: It may be that the three-way catalysis has not been cleaned regularly after long-term use, resulting in too many impurities, so the three-way catalytic engine fault lamp is lit, so the three-way catalysis of the vehicle needs to be cleaned regularly.

Not installing it has no impact on the vehicle, but it has an impact on the environment and people.

The three-way catalytic converter is actually an exhaust gas purification device, which is installed in the exhaust system of the car, and its main responsibility is to produce harmful exhaust gases including carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), etc. after the combustion of the engine, and finally generate non-toxic and harmless water, carbon dioxide and nitrogen, which is why sometimes we see water flowing out of the exhaust pipe of the car.

The combustion efficiency of current gasoline engines is only 20-30%.

Incomplete combustion of gasoline produces a variety of low-cost carbons.

Compounds, hydrosulfides and other harmful substances, three-way urging.

The role of the chemical device is to decompose these harmful substances to conform.

Automobile exhaust emission standards to protect the environment.

The catalyst in the three-way catalytic converter is rare metals such as palladium and rhodium.

It is also necessary for its normal operation to require a higher temperature.

What is the reason why the tail smell of the car is very strong after a cold start.

At this time, the exhaust temperature is low, and the three-way catalyst cannot work effectively.

Make. Can the three-way catalytic converter be dismantled? From the use.

I don't have any problems with it, and I still feel the hair.

The motivation is even stronger. If there is no three-way catalytic converter, the tail.

Air emissions can have a great impact on the environment and climate.

Passenger cars, commercial vehicles, etc., still retain the three-way catalytic converter.

Good BTW, race cars often don't have a three-way catalytic converter.

Domestic emissions from heavy-duty diesel vehicles are often substandard.

It is the main cause of automobile exhaust pollution.

Hello! Three-way catalysis refers to the catalysis of harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. The main component is a three-way catalytic converter, which is a piece of porous ceramic material that is installed in a special exhaust pipe.

It is called a carrier because it does not participate in the catalytic reaction itself, but is covered with a layer of precious metals such as platinum, rhodium, palladium, and rare earth coatings. It is the most important external purification device installed in the exhaust system of automobiles.

The working principle of the three-way catalytic converter is as follows: 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, hydrocarbons and NOx, and promote it to carry out a certain oxidation-reduction chemical reaction, in which CO is oxidized into colorless and non-toxic carbon dioxide gas at high temperature; Hydrocarbons 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.

The premise is that oxygen is still available, and the air-fuel ratio is reasonable. Hope it helps! Have a great day!

What does three-way catalysis do in a car?

The three-way catalytic converter is used to purify the exhaust gas, the three-way catalytic converter can reduce the pollutants in the exhaust gas, the three-way catalytic converter is good for protecting the earth, and the three-way catalytic converter will be installed on the exhaust pipe of every car. The three-way catalytic converter is installed at the head of the exhaust pipe, which is an important component for the car.

The exhaust pipe of the car is composed of three parts, which are the head section, the middle section, and the tail section.

The first section is the exhaust manifold, and the three-way catalytic converter is installed behind the exhaust manifold, and the exhaust gas of the engine passes through the three-way catalytic converter after it is discharged.

After the exhaust gas passes through the three-way catalytic converter, the content of pollutants and toxic substances decreases.

There are also two oxygen sensors in front and behind the three-way catalytic converter.

In front of the three-way catalytic converter is the front oxygen sensor, and behind the three-way catalytic converter is the rear oxygen sensor.

The front oxygen sensor is mainly used to detect the oxygen content in the exhaust gas, and the ECU can adjust the air-fuel ratio according to the signal from the front oxygen sensor.

The rear oxygen sensor is mainly used to detect whether the three-way catalytic converter is failing.

If the data transmitted to the ECU by the front and rear oxygen sensors is the same, it means that the three-way catalytic converter has failed.

If the three-way catalytic converter fails, the car's dashboard will light up a fault light to alert the driver.

If the three-way catalytic converter fails, it needs to be replaced immediately, otherwise it will affect the normal operation of the car engine.

How does a three-way catalytic converter work, and why do cars have to install it? Today is a long time to see.

Hello, the three-way catalysis is on the exhaust pipe, and its function is to purify the exhaust gas. 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. 】

It is the main cause of automobile exhaust pollution.

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, water and nitrogen through oxidation and reduction.

The service life of the three-way catalytic converter is roughly 8-100,000 kilometers of the car's journey in China, while it is generally 16-200,000 kilometers in foreign countries.

The maintenance of the three-way catalytic converter is generally to go to the 4S shop or a regular repair shop for cleaning and maintenance, and the maintenance cycle of the three-way catalytic converter should not be too long. If you pay more attention to the car when you use the car, it can better maintain the performance of the car and reduce the composition of harmful substances in the exhaust.

Pay more attention to the following points:

1. Cars equipped with three-way catalytic converters cannot use leaded gasoline. When the lead particles are discharged through the three-way catalytic converter with the exhaust gas, they will cover the surface of the catalyst, which will reduce the action area of the catalyst, thereby greatly reducing the conversion efficiency of the catalytic converter and leading to lead poisoning of the three-way catalytic converter.

2. The unburned mixture should be prevented from entering the catalytic converter. The temperature at which the three-way catalytic converter starts to work is around 200 degrees Celsius. After exceeding 1000 degrees Celsius, the *** component of the catalyst itself will also undergo chemical changes, so that the effective catalyst component in the catalytic converter will be reduced and the catalytic effect will be weakened.

Therefore, the following situations should be excluded during the use of the vehicle: first, idle idle for too long; second, the ignition time is too late; the third is that the individual cylinders do not work due to fire; Fourth, it is difficult to start; fifth, the mixture is too thick; Sixth, the engine burns oil, and seventh, the oxygen sensor fails; Eighth, the water temperature is too high caused by poor heat dissipation.

3. It is easy to break after a collision, and special attention should be paid when driving on uneven roads. Because most of the three-way catalytic converters are catalyst carriers formed by honeycomb pottery inside.

4. Abnormal working conditions. Stops should be stopped for inspection in a timely manner, as these conditions can lead to permanent damage to the catalytic converter.

5. Do not cut off the ignition switch when the vehicle is moving.

Three-way catalysis.

Converters and how they work.

Ternary (three-effect) catalytic converter refers to:

engine. Exhaust system.

specialized. Catalytic device.

It is capable of oxidizing hydrocarbons (HC) and carbon monoxide (CO) in the exhaust gas, and is also able to reduce nitrogen oxides (NOx) in the exhaust gas to harmless.

Nitrogen and oxygen. The catalytic converter must have a large enough surface area to ensure that enough exhaust gas is in contact with the active catalytic substances (mainly platinum, rhodium, palladium, or rare earth active substances) on the surface of the converter for a long enough time, which is generally used.

Honeycomb ceramic or metal.

Pore mesh carrier, surface coated with catalyst. Hydrocarbons (HC) and carbon monoxide (CO) with trace amounts of oxygen in the exhaust.

Oxidation reactions. Under the action of the catalyst, it will be easier to occur, i.e., the temperature at which the reaction takes place and.

The concentration of reactants will be greatly reduced. So catalytic converters can oxidize more than 90% of hydrocarbons (HC) and carbon monoxide (CO) into harmless.

water vapor and oxygen. When the oxygen concentration in the exhaust gas is very low, NOx reacts with HC and reduces to harmless oxygen and nitrogen. This is reflected in the fact that the conversion efficiency of more than 90% can be achieved under the right conditions.

Catalytic conversion efficiency is affected by a lot.

The most important factors are the concentration of oxygen in the exhaust gas (i.e. the air-fuel ratio of the mixture entering the cylinder) and the temperature of the catalytic converter. In addition, lead and sulfur, etc.

Elements can have a very negative effect on catalytic converters, as factors such as lead and sulfur interact with catalytically active substances to form new crystals.

structure or deposited on top of the catalytic substance, thereby destroying the catalytic substance.

Surface activity. This is the so-called catalytic converter poisoning, which is the most serious that affects the life of the catalytic converter.

Physical phenomena. Therefore, the premise of using a catalytic converter is:

Unleaded gasoline. Sulfur mainly has a great impact on the life of rare earth catalytic converters.

Hazardous substances. It is converted into a harmless substance, so it is called ternary.

The working principle of the three-way catalytic converter is: when the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance the three kinds of CO, HC and NOx.

The activity of the gas prompts it to undergo a certain oxidation-reduction.

Chemical reaction. Among them, CO is oxidized at high temperature to become five-colored, 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.

The three harmful gases emitted by automobile exhaust are reduced and converted into carbon dioxide and water discharge, reducing harmful gas emissions.

It's just an extra three-way catalytic converter.
