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

Guangzhou Peugeot introduce

As the earliest joint venture company in China, the Guangzhou logo has left many memories, but the biggest memory is this car. The Guangzhou 505 was the only "failed" car in the Chinese market. At that time, the 505 could be said to have unlimited glory, and the French brought their best car. Its excellent performance, luxurious equipment, and dynamic appearance allowed the Chinese people to experience luxury cars for the first time, Later, a travel model was put into production. It can easily accommodate 8 people running around. A 9-year-old 505 travel model can move at a speed of 200 kilometers per hour, demonstrating the outstanding performance of the 505! A 505 (still an unmaintained bus) that has been in production for over a decade can move forward at a speed of 80 kilometers per hour, which is quite impressive! This is 505, the earliest "good car" to enter China!
