Key points of DPF regeneration
In the process of exploring DPF (diesel particulate filter) regeneration, we need to pay attention to several core points. Firstly, it is important to closely monitor changes in back pressure, as there is a direct correlation between an increase in back pressure and an increase in fuel consumption. Specifically, for every 1 kPa increase in back pressure, fuel consumption will correspondingly increase by 0.02 to 0.04 liters per 100 kilometers. Secondly, the active regeneration of the engine is usually triggered when the back pressure reaches 7 to 10 kilopascals, and before this regeneration process starts, fuel consumption may have already climbed to the level of 0.2 to 0.4 liters per 100 kilometers. Therefore, monitoring back pressure and fuel consumption is particularly important during DPF regeneration.
The regeneration process usually lasts about 30 minutes. If the vehicle is stopped or the exhaust temperature drops during this period, such as when the vehicle is idling, the regeneration will be forced to be interrupted. To ensure that the PM in the DPF is fully consumed as much as possible, the following measures can be taken when the driver observes the regeneration indicator light on:
To ensure that the PM in the DPF is more thoroughly consumed, when the regeneration indicator light is on, the driver should follow the following suggestions: first, maintain the engine speed above 1500RPM; Secondly, try to avoid short distance driving as much as possible; Furthermore, it is necessary to prevent sudden engine shutdown; Finally, it should be ensured that the engine does not enter idle running state.
This operation ensures that the DPF can be restored to a more primitive state every time. At the same time, drivers who are allowed by the conditions can choose to drive on highways, which can improve the efficiency of passive regeneration (due to the increase in exhaust temperature, passive regeneration can continue), thereby extending the necessary period of active regeneration, which is also a fuel saving strategy to some extent.
