Detailed explanation of DPF regeneration mode

Passive regeneration

Passive regeneration is the use of NO2 in exhaust gas to oxidize carbon soot, typically carried out under normal driving conditions. This process is automatically carried out under normal driving conditions.

▣ Active regeneration during driving

When passive regeneration fails to further reduce soot or maintain a low carbon footprint, active driving regeneration will be initiated, which is accomplished through active engine injection.

▣ In situ regeneration

On site regeneration only occurs when the vehicle is stationary, and requires the driver to park and press the on site regeneration switch to activate it. During operation, it is necessary to confirm that the safety and vehicle status are suitable for regeneration conditions.

▣ In situ regeneration operation steps

The operational steps for in-situ regeneration include safety confirmation, selection of parking position, and adjustment of handbrake and gear. After confirming that there are no oil stains or combustibles on the surface and surroundings of the exhaust pipe, and that the air conditioning is turned off and the regeneration prohibition switch is not pressed, press the parking regeneration switch to start regeneration. The engine speed will increase to over 1000rpm and last for about 1 hour to complete the regeneration process.

▣ Safety precautions

Ensure that the water temperature exceeds 45 ℃ during operation, monitor safety throughout the process, and prepare fire extinguishers. If a safety hazard is found, the regeneration process can be terminated by pressing the regeneration prohibition switch or turning off the engine.
