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

JAGUAR XJ introduce

The Jaguar XJL Royal Extended Edition can be said to be a compromise made entirely for the consumption habits of the Chinese market. The car is only based on Jaguar's flagship model XJ, with an extended body and wheelbase. With a long history, the XJ series can be called the flagship of Jaguar's sedan series. The new Jaguar XJ series is an improved model launched in, with a more reliable engine and better quality, integrating technology and design, Significantly enhancing Jaguar's brand image, the all-new XJL series has been showcased in front of people after undergoing extensive technological innovations At first glance, the new Jaguar XJ still looks a bit like the old model, but upon closer inspection, you will notice that it has changed. Of course, this change is based on adhering to and preserving tradition, and the seemingly unremarkable appearance of this Jaguar can still be called a new milestone for the company's model
