Embodiment Construction

[0060]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0061] The embodiment of the present invention provides a method for analyzing the degree of ash accumulation in a DPF, referring to figure 1 , which can include:

[0062] S11. Obtain the first exhaust gas flow value and differential pressure value in the particle filter DPF;

[0063] Wherein, the pressure difference value is the difference between the pressure value when the exhaust gas flows into the DPF and the pressure value when the exhaust ...

Abstract

The invention provides a method and device for analyzing ash accumulation degree in DPF, and an electronic device. The method comprises: calculating ash factor according to the first exhaust gas flowvalue and the pressure difference value; determine whether to alarm according to the value of the ash factor. The embodiment of the method and device for analyzing ash accumulation degree in DPF, andthe electronic device can give alarm to the driver to clear the ash when the ash accumulation is large, and reduce the DPF regeneration frequency.

Description

technical field [0001] The invention relates to the field of waste gas treatment, and more specifically, relates to an analysis method, device and electronic equipment for the degree of ash accumulation in a DPF. Background technique [0002] As the emission regulations of internal combustion engines have stricter requirements on particulate PM, the particulate filter DPF, as an important component to reduce PM, is more and more widely used. [0003] The particles generated by the engine operation enter the DPF through the exhaust pipe, and the DPF collects these particles together. After the particles reach a certain limit, regeneration will be triggered. After the fuel nozzle burns the soot Soot in the DPF, Ash remains . As the mileage of the engine increases, the ash will continue to accumulate and occupy the space of the DPF, which will cause frequent regeneration of the DPF and reduce the service life of the DPF. [0004] Therefore, there is an urgent need for an anal...
