Through advanced filtration technology and high - quality materials, we ensure that our DPFs meet the most stringent environmental standards helping to improve air quality and protect the environment.

The four stages of DPF regeneration:
Phase 1: DPF carbon accumulation process (0-98%), during which the instrument panel will not provide any prompts and the vehicle can operate normally. There is no need to deliberately drive on the highway, low-speed or idle driving will not affect the DPF function.
Phase 2: DPF is just full (100% -110%), at this time the instrument panel will not give any prompts, and the vehicle can drive normally. But there is a characteristic: after starting, when the water temperature reaches 60 degrees or above, the idle speed will increase to around 1000rpm, indicating that the vehicle has entered the regeneration mode. At this point, the vehicle speed can be increased appropriately to perform a complete DPF driving regeneration, which is usually completed within 30 minutes. After completion, the idle speed will return to 750rpm.
Stage 3: DPF slightly overloaded (110% -120%), at this time the instrument panel prompts "DPF overloaded, please increase the vehicle speed or park and press the OK button to regenerate". Drive at a higher speed according to the instrument prompt. After regeneration is complete, the prompt will disappear and the idle speed will return from 1000rpm to 750rpm.
Stage 4: DPF overload (120% -140%), at which point the instrument prompts "DPF reaches limit value, please immediately park in a safe area and press the OK button to regenerate". Please follow the instrument prompt, park in a safe area, and press and hold the OK button to trigger DPF in-situ regeneration.
Steps for in-situ regeneration:
Warm up the engine (water temperature>60 ℃), park in neutral, pull the handbrake, and turn off the ignition key (or ignition switch) for 2 minutes;
Start the engine;
Do not step on the brake, accelerator, or clutch pedals. Press and hold the OK button on the steering wheel for more than 3 seconds before releasing it;
The engine speed automatically increases to 2200rpm, indicating successful regeneration triggering; If the engine speed does not increase, it indicates that regeneration has not been triggered. Turn off the ignition key (or ignition switch) for 2 minutes and repeat steps 2 and 3;
The engine speed automatically drops back to idle, and the regeneration process ends. The entire regeneration process lasts for 15-30 minutes.
By following the above steps, you can effectively avoid the prompt of DPF exceeding the limit and maintain the good operating condition of the vehicle.
