The DPF regeneration switch is usually located on the center console of the car.

Press the DPF regeneration switch button for more than 1 second, and the engine will automatically enter the regeneration state. During this process, there will be periodic changes in engine speed, which is a normal phenomenon. The regeneration process usually takes 20 to 40 minutes, and human interference may affect the system.

During regeneration, the driver should inspect the vehicle nearby and place warning signs around the engine compartment to prevent burns.

After regeneration is completed, the speed will return to idle and the DPF switch will automatically turn off, allowing the vehicle to resume normal operation. ‌

The location of DPF (diesel particulate filter) is usually installed in the exhaust system of diesel vehicles, specifically at the rear of the engine exhaust pipe.

DPF contains rare metals such as platinum, rhodium, palladium, and dense bag filters, which can effectively filter particulate matter in exhaust gas. The main function of

DPF is to reduce the emission of particulate matter (PM) pollutants in the exhaust.

The necessity and operation method of DPF regeneration: With the implementation of the National VI emission standard, the requirements for exhaust emissions are higher, and the particulate filter (DPF) has become a necessary component for capturing solid particles in exhaust gas to meet the standards. The regeneration operation generally includes steps such as parking in neutral, pulling the handbrake, turning off the ignition key, etc. Then start the vehicle and hold down the regeneration switch for 2 seconds to observe whether the engine speed increases. If the regeneration is successful, the vehicle can resume normal operation.
