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

As the oldest family of car manufacturers in the world, the Peugeot family has led the Peugeot company through the efforts of seven generations, experiencing various historical storms since the 18th century, and has come to this day. More than a century ago, when Armand Peugeot discovered in the UK that two wheelers had become an emerging means of transportation, he had long been producing coffee grinders, saws, and complete sets of tools, Peugeot, whose main business is women's skirts and steel wire skirts, is currently in a period of vigorous development. Following this, bicycles began to become popular in France, and Peugeot's bicycle production happened to replace the outdated steel wire skirts. From small and large wheeled bicycles to the first steam tricycle exhibited at the 1889 World Expo, and then to the world's earliest large-scale automobile production in 1890, The shift of the company's business focus ultimately led to the birth of Peugeot Automobile Company, leaving an important page in the history of world transportation. Since the early 20th century, Peugeot Automobile has galloped on the domestic and international automotive tracks, achieving remarkable results. Peugeot has launched numerous leading models (such as 201203404205 and 206), At the same time, it also achieved extraordinary victories in the field of competition (such as the World Rally Championship in 2000.2001 and 2002). After the 307 won the European "Model of the Year" title in 2002, the 607 achieved another market success. Peugeot began actively conducting business activities in China in the early 20th century. In March 1985, it established a representative office in Beijing. From 1985 to 1997, it established a joint venture with the Guangzhou Municipal Government and produced a total of 101000 sedans from 1985 to 1998, In April 2001, Peugeot returned to the Chinese market and sold imported cars in China through cooperation with five importers. The product series included 206CC, 307SW, 406607, and 807. In October 2002, PSA Group signed an expansion cooperation agreement with Dongfeng Motor Corporation of China, and will subsequently introduce Dongfeng Peugeot brand products to the Chinese market. In 2004, the 307 new sedan was first introduced to the Chinese market
