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

The Audi A6 is a luxury car produced by Audi, available in both sedan and station wagon models. The Audi A6's multitronic continuously variable/manual integrated transmission has achieved true continuously variable transmission for the first time in the history of luxury cars. It adopts a metal chain transmission method, completely replacing the traditional gear set transmission method, so the power output is completely free of jerks and smoother than ordinary automatic transmission, Moreover, it has the speed and sensitivity of a manual transmission, while also saving fuel and providing more comfortable handling. The newly added S gear improves acceleration ability and enhances driving pleasure. The most fascinating feature of the multi tronic continuously variable/manual integrated transmission is that it ultimately overcomes all the shortcomings of automatic and manual transmissions, surpassing their various performance in one go, and achieving a great leap in automotive transmission technology
