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 CLK introduce

The Mercedes Benz CLK is a new model of Mercedes Benz, and the CLK class sports car will be launched with a new face on the basis of the E-Class. Its interior space is more spacious, the wind resistance coefficient is lower, and the power is stronger. The model consists of a roof, electronic stability program, lighting system, head airbag, automatic rollover guard, sports package, and model overview. Due to the extended wheelbase of the 2003 CLK sports car, it is generally longer, wider, and higher than the old version, The cabin space is also wider. The strength of the car body has increased by 40%, and the drag coefficient has been reduced to 0.28cd. The side windows adopt frameless design technology, which can fully retract the doors and side body. The safety configuration of the 2003 CLK mainly includes front and side airbags, side window airbags, pre tension seat belts, and impact force limiting devices. The interior decoration materials can be selected from wood or aluminum according to personal preferences, but all CLK instruments are wrapped in chrome alloy. The rear seats are foldable, This can increase storage space. Other standard devices include wipers with sensing system, headlight assist device, and air conditioning control device. Optional parts include automatic cruise control system, xenon headlights, and voice controlled telephone. In 2010, with the release of the new generation of E-Class sedans, Mercedes Benz launched E-Coupe, which is no longer used in CLK class sports car models
