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

Kia K3 new energy hybrid vehicle introduce

The Kia K3 PHEV has been launched at the Chengdu Auto Show, with two models priced at 166800 yuan and 175800 yuan respectively after subsidies. As a pure electric plug-in hybrid model with a range of up to 80 kilometers, the arrival of the Kia K3 PHEV not only expands Kia's new energy product line, but also brings considerable pressure to several competitors. As one of the few compact plug-in hybrid products in the domestic market, the Kia K3 PHEV is a joint venture, The car is not only equipped with a power battery pack with a capacity of 12.9kWh, which enables its pure electric range to reach 80km, but also is equipped with a Kappa 1.6 GDi engine with a thermal efficiency of up to 40%, which is integrated with a long endurance electric drive system, resulting in a comprehensive fuel consumption of as low as 1L/100km. This also means that when the K3 PHEV is in a full fuel and full charge state, the car's range can reach 1080 kilometers
