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

Beijing Benz Automotive Co., Ltd. (referred to as Beijing Benz) was established on August 8, 2005. It is a Sino German joint venture jointly invested by Beijing Automotive Co., Ltd., Daimler AG, and Daimler Greater China Investment Co., Ltd. It integrates research and development, engine and vehicle production, sales, and after-sales service. Currently, Beijing Benz has become Daimler's global platform with three major vehicle models: front wheel drive, rear wheel drive, and electric vehicles, And a joint venture between engine and power battery factories has been established, and the export of core engine components and complete machines has become an important component of Mercedes Benz's global production network. Based on this, Beijing Benz has introduced the eight main models of Mercedes Benz: EQC pure electric SUV AMG A 35 L. Long wheelbase A-class sedan. Long wheelbase C-class car. Long wheelbase E-Class car. Long wheelbase GLC SUV GLB SUV and GLA SUV
