How many catalytic converters does the Chery A3 have?

[OGabriella]

There are two catalytic converters on the exhaust pipe of the Chery A3, namely the pre-catalytic converter and the main pre-catalytic converter. Definition of catalytic converter: The catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC, and NOx emitted by automobile exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. Cleaning of the catalytic converter: The cleaning method for the catalytic converter is the drip method. This method connects a plastic hose to the engine vacuum solenoid valve and relies on the air pressure in the hollow tube to draw the cleaning agent from the infusion bottle into the engine. The cleaning agent cleans the catalytic converter as it is discharged through the exhaust pipe. Service life of the catalytic converter: The service life of the catalytic converter is generally between 80,000 and 100,000 kilometers. The specific service life depends on the condition of the vehicle, and it is also related to the quality of the fuel used and the driving environment.
