threeYuanThe catalyst contains three rare metals, palladium, rhodium, and platinum, and two rare earth metals. The rare earth metals are cerium and lanthanum. The three-way catalytic converter contains these metals, so the price will be more expensive, we must be cautious when purchasing.
When a vehicle drives on the road, it needs a continuous supply of gasoline to complete it. When gasoline is burned, it will produce some harmful gases, such as carbon monoxide, hydrocarbons, nitrogen oxides, and other gases. These gases require certain treatment to be discharged from the exhaust pipe. If it is not treated, it will cause great pollution to the environment, and our health will also be affected to a certain extent.
The three-way catalytic converter is a purification device that purifies the harmful gases generated when the car is burned. The three-way catalyst is installed in the exhaust pipe, the carrier is a ceramic material, the ceramic material does not participate in the catalytic reaction, and the rare metal on the ceramic material participates in the reaction.
The three-way catalytic converter needs to use a purifying agent to turn harmful gases into harmless gases. The purifying agent can strengthen the activity of harmful gases, so that the corresponding redox reaction can occur, and the harmful gases become harmless gases. .
After the three-way catalytic converter fails, the fuel consumption of the car will increase, and the exhaust gas will easily exceed the standard. When these situations occur, it means that the three-way catalytic converter needs to be replaced in time. After we arrive at the auto repair shop, we can take away the old three-way catalytic converter and send the old three-way catalytic converter to the corresponding recycling station for recycling. .
