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

Dongfeng Xiaokang K07 II introduce

The Dongfeng Xiaokang K07 II is a van under the Dongfeng brand. It has been adjusted at the front grille, and the layered lines on the side of the body are more prominent. Compared with the old model, the exterior design of the Dongfeng Xiaokang K07 II has been slightly modified. The front grille has been adjusted, and the layered lines on the side of the body are more prominent. In terms of size, its length has increased by 80mm, The height has been reduced by 40mm. This time, we are introducing the lowest configuration model of the entire series - the 1.0L practical model. The front and rear bumpers of the car are black, priced at 29800 yuan. In terms of space, when a 176cm tall tester sits in the car, the front headroom is two fists, and the rear legroom is also two fists. The headroom is more than two fists, and the slight headroom has never been a problem. In terms of the trunk, its minimum depth is 1110mm, Folding the rear seats can expand to 1940mm, but folding them requires the use of tools, which is somewhat inconvenient. Due to the limited size of the body, the performance of the trunk can only be described as average compared to the other three models
