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

The orange body color and black stickers complement each other, resembling a warrior appearing in the desert. You can also say that it is a standard large truck because the two are indeed very similar. Americans like this type of vehicle, which can not only load a lot of goods, but also enjoy the powerful push back feeling provided by the power. The great front and rear suspension distance, This provides the best guarantee for off-road performance. The center console in the car is a combination of orange, silver, and black, which looks very comfortable and bright. Orange is distributed in the central control function area, while black is distributed in areas that are easy to reflect, such as the top of the center console. The overall style is very sedan like, which is easy to accept and recognize. American cars pay attention to comfort, and indeed, this is true. The color matching is very exciting and the operation is also convenient
