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

Peugeot 206 CC introduce

The Peugeot 206CC is the latest product showcased by Peugeot at the Paris International Auto Show. CC stands for Coupe Cabriolet, which means a dual-purpose sports car/convertible. Its feature is that it can open the roof cover and transform from a hardtop sports car to a convertible at any time. This electronic control system, controlled by five hydraulic pumps, can move the roof cover to the rear luggage compartment in just half a minute. What's more special is that, It does not need to be completely parked like other open top cars, as long as the speed does not exceed 10 kilometers per hour, the operation of opening the roof can still be carried out. The Peugeot 206CC combines the characteristics of both RVs and convertible cars, and is a very innovative compact sedan. This car was considered the most popular sedan at the Paris International Auto Show in France in October 2000
