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

Touran introduce

The Touan is a new car born on the Volkswagen PQ35 platform in 2003. This time entering the domestic market, Shanghai Volkswagen has specially created a new concept of MPS (Multi functional Sedan) for it. Although it is called different from SMPV, they are all multi-functional models born on the sedan platform, which have both the comfort of a sedan and the versatility of an MPV. The name of the Touan Touan comes from the combination of "Tour" (travel) and "- an" (representing multi-purpose), It is a multi-purpose (- an) vehicle that emphasizes comfortable travel (Tour). The Touan Touran is the first compact multifunctional sedan developed by Volkswagen in Germany, following the traditional MPV product line. It is also the first multifunctional sedan launched by Shanghai Volkswagen after long-term planning, filling the market gap between traditional sedans and MPVs, and ushering in the era of multifunctional sedans (MPS) in China The market positioning and unique design highlights of Touran's new generation of multifunctionality make it innovative in the product line of Shanghai Volkswagen. At the same time, its elegant design, versatile space, and advanced technology have also set new standards among cars in the same class
