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

Volkswagen Weilan New Energy introduce

In terms of interior design, both Volvo from Scandinavia and Volkswagen from Germany are based on simplicity. The Volvo V60 is designed with a simple yet luxurious feel, while the Volkswagen NIO maintains Volkswagen's stable T-shaped layout. It is worth mentioning that the biggest highlight of the all-new B8 in terms of interior design comes from the integrated front air outlet design, which is not a big change, but very clever. In terms of seats, The sports seat configuration of the Volvo V60 is obviously higher, with electric adjustment for both the driver and passenger seats, as well as seat memory function for the driver's seat. In contrast, the Volkswagen NIO has more options for seat adjustment. The electric backrest adjustment for the driver's seat allows for manual adjustment of the front and rear height of the seat. In addition, the front seats also have manually adjustable leg rests and headrests that can be adjusted up and down in four ways, although the configuration is not as good as the V60, However, it can provide a more comfortable sitting position. As a station wagon, storage space is equally important. In this regard, both models have their own advantages. Firstly, in terms of storage compartment settings, the Volkswagen Weilan has a more diverse storage compartment compared to the Volvo V60; In addition, in terms of practicality, the Volkswagen NIO also has advantages. Taking the storage compartment next to the rear door as an example, the Volkswagen NIO can easily accommodate two bottles of mineral water, while the V60 looks somewhat impractical; However, the advantages of V60 come from the design of some storage compartments, such as the layered design of the glove box and the multiple folding designs of the rear center armrest, which enhance the practicality of these two parts through design
