| description | The present disclosure relates to the field of engines, and in particular to a method and system for controlling DPF regeneration, as well as an engine. The method for controlling DPF regeneration according to the present disclosure includes: calculating a correction factor in real time based on a total running time and a low-load running time of an engine; determining an elapsed time, a fuel amount consumed and a mileage traveled from the last DPF regeneration to the current time, according to the time, fuel consumption and travel mileage at the time of the last DPF regeneration; determining a corrected running time, a corrected fuel consumption and a corrected travel mileage, according to the correction factor, the elapsed time, the fuel amount consumed and the mileage traveled; and judging whether the corrected running time, the corrected fuel consumption and the corrected travel mileage exceed corresponding thresholds, and triggering DPF regeneration if one of them exceeds the corresponding threshold. By calculating the correction factor, then determining the corrected running time, the corrected fuel consumption and the corrected travel mileage according to the correction factor, the elapsed time, the fuel amount consumed and the mileage traveled, and judging whether one of them exceeds the threshold to trigger DPF regeneration, DPF regeneration can be controlled according to actual working conditions to prevent the DPF from being burned out. |
