Where is the three-way catalytic converter located on the Dongfeng Fengxing?

The three-way catalytic converter of this vehicle is located at the front section of the exhaust pipe, right behind the exhaust pipe. Here is some information about the three-way catalytic converter: 1. The three-way catalytic converter is a component that almost every car has, and this device helps purify exhaust gases. 2. Without the three-way catalytic converter, the vehicle's exhaust emissions would exceed standards, and the emitted gases would also have a foul odor. 3. There are oxygen sensors both before and after the three-way catalytic converter. The oxygen sensor before it is called the front oxygen sensor, and the one after it is called the rear oxygen sensor. The primary function of the front oxygen sensor is to monitor the oxygen content in the exhaust, allowing it to send data back to the ECU. The ECU can then adjust the air-fuel ratio based on this data. The main role of the rear oxygen sensor is to check whether the three-way catalytic converter is functioning properly. If the data sent to the ECU by the front and rear oxygen sensors are the same, it indicates that the three-way catalytic converter has failed, and a fault warning light will illuminate on the vehicle's dashboard.
The location of the Dongfeng Jingyi's three-way catalytic converter is generally in the middle section of the exhaust system. After exiting the engine's exhaust pipe, it is positioned underneath the vehicle near the central area, typically right between the exhaust manifold and the muffler. As someone who frequently handles car repairs, I've noticed that in Jingyi models, it is usually fixed under the chassis, close to the central axle region. This design ensures the catalytic converter heats up quickly to effectively purify exhaust gases. During daily driving, the three-way catalytic converter is most vulnerable to impacts and carbon buildup blockages. Therefore, if the engine warning light comes on or fuel consumption inexplicably increases, it's time to suspect an issue with it. Remember to maintain the exhaust system regularly, such as checking the exhaust flow every 20,000 kilometers, to extend the catalytic converter's lifespan.
