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

On July 31, 2008, Mercedes Benz China announced the launch of the Mercedes Benz CLS 63 AMG in China, which was also the fifth vehicle launched by Mercedes Benz in China The roaring power of the 6.3-liter V8 engine is the flagship model of the Mercedes Benz CLS sports car. The CLS 63 AMG adopts AMG's developed 6.3-liter V8 engine, with a power output of 378 kW/514 horsepower and a maximum torque of 630 Nm. The strong power gives the CLS 63 AMG excellent acceleration performance, with a 0-100 km/h acceleration time of only 4.5 seconds. In addition, the exhaust system of this high-speed, naturally aspirated engine is specially designed at the rear muffler, A pair of oval chrome plated dual exhaust pipes has become one of the distinctive features of the CLS 63 AMG
