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

Tigong introduce

The Volkswagen Tiguan is a car produced by Shanghai Volkswagen, and its price was announced on March 26, 2010. This compact SUV was first introduced to consumers at the 2009 Guangzhou Auto Show. Once it appeared, it gained widespread attention and love. The appearance of the Tiguan broke the awkward situation of German cars without domestic SUV products, At the same time, it also provides consumers with more and better choices. The Shanghai Volkswagen Tiguan offers four versions, including the urban version, the fashion version, the elite version, and the flagship version, with seven models. They are equipped with Volkswagen's flagship 1.8TSI and 2.0TSI engines, which have excellent performance in both power performance and economy. Paired with a 6-speed manual transmission and an Aisin 6-speed automatic transmission, they can better exert power while enjoying the surging power, The emissions are also more environmentally friendly. Compared with the prototype Volkswagen Tiguan, the Tiguan has increased its length by 68mm and achieved a wheelbase of 2684mm, which is in the upper middle level among vehicles in the same class. The purpose is to meet the usage needs of the Chinese people. The luggage compartment of the Tiguan can freely change between 400L and 1530L, greatly improving practicality, which is also a point that must be paid attention to as an SUV model
