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 307 introduce

The Weiwang 307 is an extended version of the Weiwang 306, with a length of 4495mm and a wheelbase of 2920mm. As a result, the Weiwang 307 has a larger rear space. The front face of the Weiwang 307 has a more overall feel, and the two mesh grilles make the vehicle more refined and upgraded to a certain extent. The red BAIC logo is also quite festive. It has an additional window on the side that can be opened, which can be used by rear passengers for ventilation and breathability, The interior environment of the Weiwang 307 will become better. Of course, the interior design of the Weiwang 307 is mainly practical, with a simple and simple console design that has obvious Japanese micro car characteristics. The speedometer is a traditional scale, and information such as the tachometer, water temperature gauge, oil gauge, and time are displayed through the digital instrument panel on the right. The Weiwang 307 can be equipped with four rows of seats, and the maximum number of passengers in the car can be increased to 9. If only two rows of seats are selected, So most car owners plan to use this car as a truck. After removing the rear seats, the rear compartment forms a complete loading space. In addition, there are many small storage spaces available on the Weiwang 307, which is very convenient. In terms of power, the Weiwang 307 currently only has a 1.2L four cylinder engine, with a maximum power of 63.5kW and a maximum torque of 108Nm. It is equipped with a 5-speed manual transmission and adopts rear wheel drive. The low-end models do not have steering assistance, making it difficult to turn the wheels in place
