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

China H330 introduce

On April 20, 2013, the Huachen Zhonghua H330 model will be officially launched at the Shanghai Auto Show The length, width, and height of the H330 body are 4510/1755/1460mm respectively; The new intake grille design continues the design of models such as H530 and V5, and the redesigned headlights are also designed in the same style as the H320. However, the bumper design of the H330 will be different, unlike the sporty style of the H320 model. The lower intake grille adopts a connected design, integrating the grille in the fog light area with the lower intake grille of the bumper, highlighting a more atmospheric and stable atmosphere The interior design of H330 and H320 are completely identical, mainly with significant modifications to the central control panel based on the FSV, continuing the design style of the previous H530 model, with a smoother transition to the transmission gear lever area. The new transmission panel is more aesthetically pleasing
