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 introduce

The BYD Subaru is a new model launched by BYD after its brand strategic transformation. The biggest highlight of this car is its remote control driving technology, which allows drivers to control the vehicle within a visible range of 20 meters around the vehicle through the remote control key. The Subaru's remote control driving technology won the Best Leading Technology Award at the 2012 Beijing Auto Show. Equipped with a 1.5T turbocharged engine, the BYD Subaru has a maximum power of 154 horsepower, The acceleration from 100 kilometers per hour of this car is 8.9 seconds. As a premium model of BYD, BYD has invested more in the Sagitar and advanced towards a higher level of design philosophy. The interior of the car is relatively fashionable, atmospheric, and the exterior has perfect lines, ensuring safety, quality, and reliability
