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
The New Sail is an "international quality small car" developed by Shanghai General Motors and the Pan Asian Automotive Technology Center in China. It is an ideal family sedan developed by Chevrolet specifically for families with mechanical happiness. With affordable prices and complete configurations, it became the benchmark for family sedans at that time. There have been significant improvements in appearance, interior, and configuration, and the engine has been re tuned to be more fuel-efficient, with emissions meeting Euro 4 standards and Euro 5 standards, Make the new Sail more favored by consumers. The body size of Chevrolet's new Sail has also been slightly modified. The length of Chevrolet's new Sail S-RV is 4097mm, 71mm longer than the original Buick Sail S-RV, while the width remains 1608mm, the height remains 1448mm, and the wheelbase remains unchanged at 2443mm
