Is three-way catalysis important to exhaust system?

Personally, three-way catalysis is very important for the exhaust system and even for the overall performance of the vehicle.

First of all, what is the use of three-way catalysis? Simply put, it is to convert the exhaust gas and harmful gas generated by our vehicle engine into harmless carbon dioxide, water and nitrogen through oxidation and reduction. Three-way catalytic converter is the most important purification device in China's automobile exhaust system.

After knowing what three-way catalysis is, let's talk about its importance to exhaust system and vehicles. Three-way catalysis can not only purify harmful air, but also improve the performance of vehicles through proper maintenance. Because the fuel quality in China is generally poor, the fuel contains sulfur and phosphorus, and the antiknock agent used contains manganese. When we use the vehicle for a long time, these chemical components will form chemical complexes with the exhaust gas after combustion on the surface of the oxygen sensor and inside the three-way catalyst. In addition, when the driver has bad driving habits or drives under bad conditions for a long time, the engine is often in an incomplete combustion state, which will form carbon deposits in the oxygen sensor and the three-way catalyst. Therefore, due to various factors, the damage of three-way catalysis will lead to the abnormal operation of the engine, resulting in problems such as increased fuel consumption, decreased power and excessive exhaust gas.

So at this time, we can see how important a good three-way catalysis is to the exhaust system and vehicle performance. The test in China shows that the performance, driving quality and acceleration performance of well-maintained and clean three-way catalytic converter vehicles have been improved, and the fuel consumption has also been reduced. The exhaust gas detection results including the exhaust system are also excellent.

? An excellent three-way catalyst can obviously reduce CO, HC and NO in automobile exhaust, especially NO, which can reduce fuel consumption, improve cold start ability, improve vehicle performance and even reduce noise.
