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 popular S500 introduce

The Fengxing S500 is Dongfeng Fengxing's first all-around family 7-seater MPV, launched in 2015. It was officially unveiled at the Shanghai Auto Show in April 2015. With Fengxing's 15 years of deep cultivation in the MPV market, the Fengxing S500 breaks through traditional thinking and takes the lead in proposing the idea that "MPVs can also become the first family car" in the market, overturning the inertia of "consumers only buy MPVs when they buy the second car" in the market The S500 fully matches the purchasing needs of the "first car" in terms of exterior and interior design, spatial layout, configuration level, and power experience, creating the first choice for families to purchase. The 2019 Fengxing S500 has launched four models (new practical models), all equipped with 1.5L engines, with a price range of 59900 to 70900 yuan
