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

HiLux introduce

The Toyota HILUX (imported) TOYOTA HILUX is an SUV that leans towards road performance. Toyota has always been a loyal supporter of SUVs, and compared to the LC series PRADO, HILUX places more emphasis on road performance. Although it has been rooted in the North American market for many years and has sold over 1.2 million vehicles (known as 4RUNNER in North America), most people who buy it will not use it to travel mountains and rivers, The spacious interior and powerful design make it a competent SUV. Although the TOYOTA HILUX SURF provides passengers with a luxurious road riding experience, it still has a certain ability to endure hardships. The secret is the non constant TORSEN variable four-wheel drive mode, combined with the latest technology, similar to Land Rover's HDC downhill control system, which has TOYOTA's deep off-road capabilities, The powerful power system is also its advantage. Although it still uses the previous generation power system, the top tier 3-liter diesel engine can reach a maximum torque of 35.9kgm, and the North American version of 4RUNNER is even equipped with a top tier 4.7 displacement 235 horsepower gasoline engine
