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

At the 2017 Shanghai International Auto Show, Land Rover officially released its latest model, the Range Rover Vein. The new car belongs to the Range Rover family and is positioned between the Range Rover Evoque and Range Rover Sport. The Range Rover Vein adopts the same platform development as Jaguar F-PACE, and has improved its lightweight level. In addition to traditional power models, it is also expected to be equipped with pure electric power. After integrating the Range Rover and Discovery product lines, the Land Rover brand has already launched a new generation of models. In Land Rover's view, the Range Rover, Range Rover Sport, and Range Rover Evoque series of products cannot meet the needs of segmented markets. This Range Rover Vein the future may not be able to meet the needs of the market segment. Direct competition from BMW X4, Mercedes Benz GLC Coupe, and others
