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: 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
After being launched in May 2011 and operating under the concept of "passenger truck" for more than half a year, Hagrid pickup trucks have gradually faded out of people's sight for some reason. They have been replaced by the name "Yujun", which some people understand as "driving the wind", hoping to one day surpass the wind. Later, Hagrid Automobile named their 4JB1TI diesel pickup truck "New Isuzu" pickup truck, which is manufactured by Chengdu Engine Factory, Originating from Isuzu Technology in Japan, it is named the "New Isuzu" pickup truck to distinguish it from other pickup truck products with Isuzu Technology engines on the market. However, the name "Yujun" is still used. Currently, the official name of this pickup truck product should be "Hagrid Yujun"
