What is a three-way catalytic converter? A three-way catalytic converter is the most important external purification device installed in a car's exhaust system, which can remove CO from the car's exhaust Harmful gases such as HC and NOx are converted into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Simply put, they purify the exhaust gas. The working principle of a three-way catalytic converter is as follows: 1. When the engine exhaust gas is discharged through the exhaust pipe, due to the catalytic effect of the purifying agent in the three-way catalytic converter, the activity of C0, HC, and NOx is enhanced, leading to oxidation and reduction reactions. 2. C0 is oxidized to colorless and non-toxic C02 at high temperatures, HC compounds are oxidized to H20 and C02 at high temperatures, while NOx is reduced to N2 (nitrogen) and 02 (oxygen), thereby purifying the engine's exhaust emissions)

Method for installing a three-way catalytic converter

Method for installing a three-way catalytic converter: ① Use 8 bolts to install 2 heat shields on the new preheated three-way catalytic converter. ② Install the new gasket, protective ring, and sealing gasket onto the preheated three-way catalytic converter. ③ Use 3 bolts and 2 new nuts to install the preheated three-way catalytic converter with a tightening torque of 29N. m. ④ Use bolts and nuts to install the exhaust manifold bracket with a tightening torque of 42N. m. ⑤ Use bolts and nuts to install the No.1 exhaust manifold bracket with a tightening torque of 42N. m. ⑥ Connect the secondary oxygen sensor connector

From the feedback from Huapu's car enthusiasts forum, it can be seen that major problems are not common, and small problems are constantly a common problem. Here, I just want to say that there are also quite a few million BMW problems, and everything has problems that are not perfect. The 50000 yuan sedan, at such a low price point, is quite attractive. Based on the information I have learned, let me tell you about the Huapu Langfeng: the predecessor of the current sea area is the Langfeng, Later it was changed to a sea area, and now many of the sea areas on the forum are old models of the Langfeng. This car was once popular, but unfortunately it did not continue to develop. Even the Huapu brand was not retained, and now it has been changed to the UK, a joint venture brand. Currently, the Huapu Langfeng has been discontinued, and because it is an older model, many configurations are not as good as the current car. Therefore, it is recommended that those who purchase a second-hand Huapu Langfeng should change to a different model
