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

BAIC Weiwang 407EV New Energy introduce

In terms of appearance, although this car is a pure electric box truck, its appearance tends to be designed in the style of a concept car. Because it does not need to collide with the wind and dissipate heat like an oil burning motor vehicle, the front face of the car only uses a banner style black paint decorative panel, which is integrated with daytime running lights, making the entire truck look full of texture. Although the rear end is relatively square, the rich line design gives the rear end a certain sense of hierarchy, The rectangular tail lights with a vertical bar style are also very stylish, and the lighting effect is stunning. According to the vehicle positioning, the Weiwang 407EV can not only enter through the rear door in crowded streets, but also through the sliding door on the right side. The tail door adopts a 4/6 ratio split design, making it more convenient and flexible to get off and transport goods. The entire trunk volume of the car is 4.5 cubic meters, and the load capacity can reach 810kg
