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 Mercedes Benz ML is a mid to large SUV class of Mercedes Benz cars, positioned higher than the GLK and lower than the G and GL classes. The Mercedes Benz M-Class is an SUV model that combines driving comfort and power performance. Unlike the G series, which emphasizes only off-road performance, the ML series emphasizes luxury and comfort, or can be said to be urban driving. The main competitors of the Mercedes Benz ML class are the BMW X5 and Lexus GX, which are better at sports style compared to their competitors, The Mercedes Benz ML Class has put a lot of effort into comfort. The interior materials are carefully selected and the configuration is very rich. There are four versions of the power system for the domestically launched Mercedes Benz ML Class: 3.0L V6.3.5L V6.5.5L V8 and 5.5T V8
