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

Audi S8 introduce

The Audi S8 is the sporty performance version of the Audi A8. The all-new Audi S8 is only modified from the new A8 in terms of exterior and interior details. In terms of exterior design, the Audi S8 is not much more aggressive than the regular A8. In terms of power, the all-new Audi S8 is equipped with a 4.0TFSI twin turbocharged engine, with a maximum power of no less than 520 horsepower and a continuous torque output of 650N · m at 1700rpm-5500rpm. Audi launched the first generation S8 as early as 1994, As the sport version of Audi's top luxury car A8, it applied all of Audi's top technologies at the time, such as an all aluminum body frame and full-time four-wheel drive. Luxury cars were originally aimed at high-end demand, and most of them should be aimed at rear seat users, so the sport version S8 that leans towards driving pleasure is definitely only aimed at a few out of a few. Audi had been optimistic about this niche market for a decade, and now continues to make every effort to launch the new generation S8, And still playing the role of "Audi's cutting-edge technology collection"
