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

Mercedes Benz CLS260 introduce

A few days ago, Mercedes Benz launched a new CLS260 model in the Chinese market, which was equipped with a 1.5T engine for nearly 600000 yuan, becoming a hot topic in the automotive industry. Recently, official images of the new car have also been exposed on the internet. In terms of design, the appearance of the CLS260 is basically consistent with the current higher-level model, continuing the low and smooth body lines of previous models. The waistline of the new car has been greatly simplified, It looks very simple. The contour lines at the rear are very clean, and the trapezoidal slanted tail light group uses LED light sources, with no other unnecessary designs. As an entry-level model of the CLS, the CLS 260 maintains a high degree of consistency in appearance design with other versions, equipped with full LED headlights as standard. 19 inch double five spoke wheels, and AMG exterior sports components will be optional
