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

Wuling Rongguang Mini Card introduce

Wuling Rongguang small truck is a model specially produced by Wuling for the increasingly competitive small truck market. Wuling's vans are undoubtedly the king of their kind, which is well-known. However, Wuling's small trucks are far from as glamorous as Chang'an, with a low chassis and high accessory prices, The unsatisfactory cost-effectiveness has always led to low sales of Wuling series trucks. However, the Wuling Rongguang small truck launched in late 2011 broke this situation. Although there was still no improvement in the issue of low chassis, the 1.2-liter displacement and 2.75-meter cargo box matched it surpassed the Changan New Leopard, which has always been known for its large cargo box! The relatively cheap price allowed this model to achieve impressive sales results in just a few months after its launch. Based on our sales data, if we maintain this market situation, it may only take 5 years or even less. In terms of market share of small trucks, Changan will have to hand over the first place to Wuling
