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

Mercedes-Benz GLE400 introduce

The appearance of the Mercedes Benz GLE400 is very similar to that of the AMG GLE43, with a family style front face, LED daytime running lights, low beams, and high beams. The central grille adopts four hollow chrome decorative strips (similar to the GLE43), and the lower front bumper is also similar to the GLS450 GEL43. The overall line is very smooth, mainly made of chrome decorative materials. The welcome pedals are very Mercedes Benz style, and the five pairs of wheel rims are closer to the design of the AMG GLE43, But the overall effect is more stable without smoky black. In terms of configuration, it supports Android, Apple car play, full-time four-wheel drive, aluminum 20 inch wheels, electric 4-way lumbar support, smartphone connection, Harman sound, automatic air conditioning, ambient lighting, anti-theft alarm, colored heat-insulating glass, electrically folding rearview mirrors, electric sunroof, knee airbags, front side airbags, tire monitoring, blind spot monitoring, distance radar, automatic braking, parking assistance, multiple driving modes, fatigue driving Driving reminder, lane change assistance, 360 surround image, and so on. In terms of power: The 2019 Mercedes Benz GLE400 is equipped with a 3.0T twin turbocharged V6 direct injection gasoline engine, with a maximum horsepower of 333 and a maximum torque of 480 Nm. It is matched with a 9-speed automatic transmission, although not as aggressive as the AMG GLE43, the overall driving experience is full of power
