What is a three way catalytic converter?

The three-way catalytic converter can convert harmful gases such as CO carbon monoxide, HC hydrocarbons and NOx nitrogen oxides emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction, which plays an environmental role.

The working principle of the three-way catalytic converter is that when the high-temperature automobile exhaust passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of CO, hydrocarbons and NOx three gases, and promote it to carry out a certain redox chemical reaction, wherein 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.

The specific working process of the three-way catalytic converter is as follows:

As the high-temperature vehicle exhaust passes through the purification device, the catalyst in the three-way catalytic converter will enhance the activity of the three gases: carbon monoxide, hydrocarbons and nitrogen oxides.

It is prompted to carry out a certain redox-reduction chemical reaction on the surface of the catalytic converter: carbon monoxide is oxidized to colorless and non-toxic carbon dioxide at high temperatures, hydrocarbons are oxidized to water and carbon dioxide at high temperatures, and nitrogen oxides are reduced to nitrogen and oxygen. In this way, the three harmful gases have become non-toxic and harmless common gases, and the car exhaust gas can be purified.

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. Because this catalytic converter can simultaneously convert the main hazardous substances in the exhaust gas into harmless substances. 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 three-way catalytic converter is the most coarse and important external purification device installed in the automobile exhaust system, which can convert harmful gases such as CO carbon monoxide, HC hydrocarbons and NOx nitrogen oxides discharged from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction.

3. Because this catalytic converter can convert the three main harmful substances in the exhaust gas into harmless substances at the same time, it is called ternary.

Three-way catalytic converter is an important equipment used for automobile exhaust emission purification. It is a kind of catalyst that converts harmful gases (such as carbon monoxide, nitrogen oxides, unburned hydrocarbons, etc.) emitted by vehicles into relatively harmless water vapor, carbon dioxide and other substances to reduce the pollution of automobile exhaust to the environment. The three-way catalytic converter is mainly composed of a ceramic substrate, an active catalyst and a shell.

In general, carbon monoxide, hydrocarbons and nitrogen oxides (NOx) in vehicle exhaust are converted into carbon dioxide, nitrogen and water vapour. The catalysts used to catalyze the reaction are also different in different situations, including platinum, palladium, and ruthenium. During normal operation, the three-way catalytic converter is easy to operate and maintain.

However, long-term poor driving conditions, such as idle operation, too thick fuel, high temperature congestion and high noise congestion, improper use and other factors, may lead to the failure of the three-way catalytic converter, and the catalytic converter needs to be replaced.

Hello, the catalytic converter is a kind of equipment used to reduce the emission of residual gas in vehicle exhaust. It is installed above the exhaust pipe of the car and is used to purify harmful gases from the emissions. The main function of the three-way catalytic converter is to convert harmful substances such as carbon monoxide, nitrogen oxides, and hydrocarbons in the exhaust gas into environmentally friendly substances such as carbon dioxide, nitrogen, and water.

This process is achieved by coating a catalyst inside the vessel.
