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
