Where is the catalytic converter located in a car?

[VonEmerson]

The catalytic converter is located at the front end of the car's exhaust pipe. It is an important external purification device in the vehicle's exhaust system. Its function is to convert harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides from the car's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The steps to clean the catalytic converter are: 1. Use a lift to raise the vehicle and remove the catalytic converter; 2. Soak and clean the catalytic converter with an oxalic acid solution, then rinse it with clean water; 3. Reinstall the cleaned catalytic converter and start the vehicle for testing. The benefits of cleaning the catalytic converter include: 1. Helping to improve the performance of the vehicle's engine; 2. Reducing frequent alarms from the exhaust system's oxygen sensors.
