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

Isuzu D-MAX introduce

The domestically produced Isuzu D-MAX pickup truck was officially launched on December 7th. The new car will be equipped with a 2.5T diesel engine and offer optional four-wheel drive models. A total of six models have been launched. The length, width, and height of the domestically produced Isuzu D-MAX are 5295mm/1860mm/1795mm, respectively, and the wheelbase has been extended to 3095mm, which is quite impressive. The double row seat design is very suitable for domestic users, and the standard 5-seat design can meet daily use needs. The domestically produced Isuzu D-MAX adopts a 5-seat design, The high-end models are also equipped with leather seats and electric adjustment functions, and the comfort configuration is not poor. The biggest highlight is still the rear seats, and legroom is usually the soft rib of a pickup truck. However, the D-MAX's rear seats are very spacious, and the backrest angle also has a certain tilt. The Isuzu D-MAX offers two body height models, and the four-wheel drive version has a minimum ground clearance of 205mm. In terms of power, the overseas version of the D-MAX has two versions of diesel engines, 2.5T and 3.0T, But the domestically introduced D-MAX will only be equipped with one 2.5T diesel engine, with a maximum power of 100kW (136PS) and a maximum torque of 320Nm
