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

HONDA ACCORD introduce

Honda's initial goal in building the Accord was just to create a typical hatchback with a V6 engine. The original English meaning was coordination, and Honda also hoped to build a car that coexists harmoniously with people and society. The Accord was introduced in Japan in 1976 and has gone through more than 30 years of growth in 8 generations. It is a history of constantly upgrading the standards of sedans it has created. From the appearance, the changes in the new Accord are reflected in the concept, while the old Accord is stable and stable, The new Accord, on the other hand, is full of dynamism. The integrated headlights are triangular in shape, very aggressive, with curves sweeping from the front to the side. The surface of the car has a perfect trendy curve, and the body has a sense of fashion. Safety and quality are reliable, and the interior is elegant
