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 highly anticipated Volkswagen's first domestically produced SUV, the Tiguan, received reliable news in February 2010 and will announce its price on March 26, 2010. This compact SUV first met consumers at the 2009 Guangzhou Auto Show and gained widespread attention and love upon its appearance. The appearance of the Tiguan broke the awkward situation of German cars without domestically produced SUV products, At the same time, it also provides consumers with more and better choices. Currently, the Tiguan has been exhibited at Volkswagen 4S stores in Shanghai, Beijing, for consumers to further understand. Volkswagen Tiguan is equipped with a variety of safety features this time, and the entire series is equipped with an ESP body stability system as standard EBD electronic brake force distribution and ASR traction control, such as some rare EDS electronic differential locks The EPB electronic handbrake, automatic parking function, and TPR tire pressure monitoring system have all become standard features of the Tiguan, indicating that Volkswagen attaches great importance to safety. The front double airbags and front side airbags can ensure the driving safety of passengers, and the standard child lock also values the safety of children. In short, the Tiguan's sincerity in safety configuration is enough to impress the Chinese people
