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

Mileage (overseas) introduce

Honda grandly launched its first generation of mileage in 1968. As the flag of the sedan series, mileage reflects the quality of luxury cars in many aspects. The interior is natural and elegant, and the materials are luxurious and elegant, creating a harmonious and pleasant cabin atmosphere. However, as a flagship car, mileage is not very well-known in China, It is obvious that Honda still lacks the strength to compete with world luxury brands in high-end cars. Although Honda has invested a lot of effort in mileage, it is not easy to enter the luxury car market. From the appearance, the mileage is still quite luxurious, but overall in pursuit of solemnity, it appears somewhat conservative. The design of the front headlights lacks modernity, and the body lines are too rigid. It is worth mentioning that the design of the radiator grille is somewhat innovative, Simple yet atmospheric. The body has a perfect curve and reliable quality
