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

Fiesta introduce

In the summer of 1976, Ford Motor Company launched the first generation Fiesta to the market. The basic model was equipped with a 1.0-liter engine, with a power of 30 kilowatts. The entire vehicle weighed only 700 kilograms, making it the lightest among similar cars. The 1.2 cubic meters of cargo space was also the largest among similar cars. It had the best panoramic view and a drag coefficient of 0.42 compared to other cars at that time. The small drag coefficient greatly reduced fuel consumption, with a fuel consumption of only 5.6 liters per 100 kilometers at a speed of 90 kilometers per hour, At a speed of 120 kilometers per hour, the fuel consumption per 100 kilometers is 8.2 liters, and when driving in the city, the fuel consumption per 100 kilometers is 7.9 liters. Fuel economy was a key factor for the success of the Ford Fiesta in the era of energy crisis, but this was not its only advantage. Through strong technological innovation, the Fiesta proved that size is not the only measure of car value
