Its main role is to collect and burn soot particles produced during fuel combustion. Without this filter, pollutant emissions would significantly increase, contributing to poor air quality. Regeneration therefore helps maintain the system’s efficiency, thereby reducing the vehicle’s environmental impact. The Different DPF Regeneration Methods There are several methods for regenerating the particulate filter, each with its own specific characteristics: Passive Regeneration Passive regeneration occurs naturally when the engine reaches high temperatures. When driving at speeds above 110 km/h (70 mph) for distances of approximately 50 kilometers (31 miles), the DPF heats up sufficiently to burn off accumulated particulate matter.
Active Regeneration Active regeneration is a process that is automatically triggered by the vehicle when the particulate matter level reaches a critical threshold. This method uses an additional fuel injection to increase the filter temperature and burn off the residue. Stationary Regeneration This method is similar to active regeneration, but occurs when the vehicle is stationary. This type of regeneration is often necessary after a previous regeneration failure and requires driver intervention to initiate the process.Additive Regeneration
By adding an additive to the fuel tank, it helps lower the melting point of particulate matter, facilitating its combustion during high-speed driving. This method requires driving at a steady speed to ensure its effectiveness.
Regeneration by DecarbonizationFinally, regeneration by decarbonization is a procedure that must be performed by professionals.
