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

BYD L3 introduce

From the perspective of BYD's product system, the F3 is gradually moving towards the low-end, the G3 is moving towards the mid-range, and the L3 will be the first bullet in BYD's mid to high end models. The positioning of this car will be close to or slightly higher than the currently available compact car G3. With BYD's consistent high cost-effectiveness, it is expected to compete in the higher end automotive market and potentially impact the current compact car market dominated by joint venture brands The L3 front face features a wide and thick dual horizontal bar intake grille that is simple and atmospheric; The overall shape of the front headlights adopts a tear eye design, while the smoked black design adds a sporty style to the entire vehicle. The engine hood also adopts the popular raised design, making the overall style very linear and powerful. It can be seen that the L3 has surpassed the past in appearance design, forming a distinct style. The tail lights are designed with popular LED lights, which exude a grand, fashionable, elegant temperament, and reliable safety and quality
