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

BAIC 212 introduce

BAIC 212 Series: Founded in 1958, Beijing Automotive Manufacturing Co., Ltd. is a representative of BAIC's independent brand. For more than 40 years, BAIC has focused on the development and production of light off-road vehicles and trucks, and has won the reputation of "off-road family". The BAIC BJ-212 was first developed in 1964, and in 1965, the BJ-212 series off-road vehicles were officially finalized. The BJ-212 at that time adopted a detachable soft top design, The BJ-212 Jeep is mainly used for commander riding, weapon transportation, and other purposes. It adopts front and rear steel plate spring non independent suspension, which has strong off-road capabilities. It finally achieved mass production in 1966. In terms of body size, its length, width, and height are 3910mm, 1760mm, and 1880mm respectively, with a wheelbase of 2310mm. In terms of power, the BJ-212 Jeep is equipped with a 2445cc inline four cylinder gasoline engine, which adopts four-wheel drive and front and rear drum brakes, Matched with the engine is a 3-speed manual transmission, which has a maximum power of 75 horsepower, a maximum torque of 172 Nm, a weight of 1395kg, a maximum speed of 120-130 km/h, and a fuel consumption of approximately 14L per 100 kilometers
