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

JAC iEVS4 introduce

The Jianghuai iEVS4 is an electrified upgrade based on the gasoline version of the Ruifeng S4. In terms of appearance, everyone should not be too unfamiliar with it. The overall appearance maintains the original design style of the Ruifeng S4, but makes some changes based on the characteristics of pure electric vehicles. The grille is no longer hollow, but adopts a fully enclosed design, with DC fast charging and AC slow charging interfaces below the middle cover plate. In terms of headlights, except for the lowest configuration model which uses halogen light sources, All other configurations use LED light source headlights and are equipped with lenses. The side dual cultivation creates a floating roof effect, with body dimensions of 4410/1800/1660mm in length, width, and height, and a wheelbase of 2620mm. The exterior rearview mirror only supports electric adjustment and does not support electric folding. In addition, the car does not have a 360 degree imaging function
