What is a three-way catalytic converter?The role of three-way catalytic converter

threeYuanCatalytic converter is a purification device, its role is to reduce most of the exhaust pollutants emitted by the engine.Although the three-way catalytic converter is installed outside the body, the position of the chassis is not easy to observe, so it is almost difficult for usFindThe figure of the three-way catalytic converter, unless the vehicle is raised.

Three-way catalytic converter-a key component of automobile exhaust purification

The three-way catalytic converter is installed behind the exhaust manifold of the engine. Although the shape of a metal shell looks cheap, it is actually very expensive. The carrier component of the three-way catalytic converter is a porous ceramic material, and the surface is covered with a layer of platinum, rhodium, palladium and other precious metals and rare earth coatings. These precious metals are expensive and have also led to many criminals to steal the three yuan. Catalytic Converter.

With a three-way catalytic converter, when exhaust gas containing harmful gases such as carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) passes through it, it is oxidized and reduced to non-toxic under the action of platinum, rhodium, and palladium. Harmless water (H₂O), carbon dioxide (CO₂), nitrogen (N2) and oxygen (O2).

The most common fault of the three-way catalytic converter-blockage

With the prolonged use of the vehicle, the blockage of the three-way catalytic converter will become more and more obvious. If the fuel consumption of the vehicle is significantly increased, the power is reduced, the acceleration is weak, and the exhaust gas has an obvious smell, after eliminating other possible faults, it is likely to be three-way The impact caused by the blockage of the catalytic converter. Generally, regular cleaning can be used to alleviate the clogging of the three-way catalytic converter, but if you want to solve it completely, you can only choose to replace the three-way catalytic converter.

How to maintain the three-way catalytic converter?

1. A major factor that causes damage to the three-way catalytic converter is the fuel that the vehicle fills. If the fuel quality is poor, the three-way catalytic converter is easily damaged;

2. Do not idling the engine for a long time;

3. When driving through potholes, slow down the speed to avoid hitting the chassis with too fast speed, which can easily damage the three-way catalytic converter.
