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: 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
As the top of the line model, the Mercedes A220L4MATIC has a 2.0T engine, four-wheel drive system, and independent rear suspension, with more luxurious interior and exterior configurations. Overall, it is the complete complement to the all-new A-Class The 019 Mercedes Benz A220L4MATIC has been launched and sold. The manufacturer's suggested retail price is 29.98 million yuan, and it is equipped with a 20T turbocharged engine with a horsepower of 190Ps. To some extent, the all-new Mercedes Benz A220L is more like a microcosm of Mercedes Benz's luxury lineage. Even if it is positioned as the most entry-level A-Class, you can still see the most cutting-edge and trendy designs in the Mercedes Benz family from it
