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

The large curved body surface, headlights, turn signals, and scattered front grille, as well as the huge wheel arches and hidden spare tire rack that affect the rear view, all inject new inspiration into the calm and stable SUV design The VehiCROSS series is equipped with a 3.5-liter 24 valve V6 engine, which is the most powerful engine equipped by Isuzu in SUVs, with a maximum power of 160kW and a maximum torque of 312Nm The VX-4 is equipped with an all aluminum engine and a 4-speed automatic transmission, and uses the "Instant Torque (TOD)" automatic full-time four-wheel drive technology, which can obtain the required power according to climate and road conditions. Under normal driving conditions, the TOD system behaves as rear wheel drive, but when the road conditions change, it will transmit torque to the front wheels as needed to provide sufficient grip TOD uses 12 sensors to detect the working status of each half axle, including vehicle speed, axle speed, throttle opening, braking, and ABS system status, to prevent tire adhesion loss
