If the regeneration process of DPF (diesel particulate filter) is interrupted, it may lead to a series of adverse consequences. Specifically:

Filter blockage: The regeneration process of DPF is to clean up the accumulated particulate matter inside. If regeneration is interrupted, these particulate matter will continue to remain in the filter, which may lead to filter clogging over time. A clogged DPF can restrict exhaust flow, thereby affecting engine performance, leading to increased fuel consumption and emissions.

Fault warning light on: When the DPF fails to regenerate properly, the engine management system may detect abnormalities and trigger the fault warning light. This reminds drivers to inspect and repair their vehicles as soon as possible.

Violation of regulations: In some regions, strict emission regulations require vehicles to maintain low emission levels. If the DPF fails to regenerate sufficiently, emissions may exceed regulatory limits, leading to fines or other legal issues.

Equipment damage: In extreme cases, if the DPF experiences overheating or other damage during regeneration, the entire filter may need to be replaced. This is an expensive repair and may affect the normal use of the vehicle.

To avoid these potential issues, it is recommended that car owners conduct regular DPF checks and regenerations. If the regeneration process is interrupted or malfunctions are found, professional automotive technicians should be contacted in a timely manner for inspection and repair. At the same time, car owners can also take some preventive measures to reduce the risk of DPF blockage, such as increasing vehicle speed and driving regularly on highways, which can help keep DPF unobstructed.
