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: 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
As a brand new series within the Audi family, the Audi S5 is positioned in the passionate segment of high-end two door sports cars. This is a charming car series that perfectly combines Audi's usual dynamic design, exciting power and handling performance, and excellent manufacturing technology. It is a new interpretation of Audi's brand concept of "breaking through technology and inspiring the future" The S series is the most sporty car series in the Audi family. Although there is still some gap between it and the rarer RS series, as car enthusiasts, they still take pride in owning an S series. In the sunlight, this white S5, when paired with Roman style architecture, appears particularly pure and noble. In my eyes, what I see more is the artistic characteristics that Audi A6L and A4 do not have. The slender body, perfect body lines and surfaces, and the interplay of light and shadow, are lifelike, giving the car a sculptural sense of art. The advantages of Audi S5 are self-evident, as it pushes Audi's fashion design language to a new height
