Parking regeneration

For parking regeneration, the vehicle needs to be stopped and allowed to stand still. If the DPF indicator light is flashing and the pace is increasing, it indicates a high carbon load, making it difficult for the vehicle to complete regeneration on its own. At this point, the driver needs to stop and take human intervention measures, which is usually relatively simple and can be completed by the driver themselves.

When the carbon load indicator light is continuously on, the vehicle should be driven to a safe area away from crowds and flammable and explosive materials for parking regeneration operations. Manual regeneration steps, including parking and handbrake, need to be performed in a safe area. Firstly, ensure that the vehicle comes to a stable stop, shifts to neutral, applies the handbrake, and keeps the engine running while keeping the water temperature above 65 ℃. Next, press the DPF regeneration switch to initiate the regeneration process of the aftertreatment system. During this process, the engine will inject diesel into the DPF system, using the high temperature generated by combustion to burn and exhaust the filtered particulate matter. Regeneration tasks usually take 40-50 minutes. Once the carbon load indicator light goes out, it means that the parking regeneration has been successfully completed.

It is worth noting that the oil level may rise during the regeneration process. This is mainly due to the increased idle speed of the engine during regeneration, which maintains high levels of torque and speed, resulting in an increase in diesel consumption. Partially unburned fuel will flow into the oil pan along the cylinder wall, causing the oil level to rise. But usually, after regeneration is complete, the oil level will return to normal levels.
