Embodiment 1

[0049] Such as Figure 1 to Figure 3 As shown, this embodiment provides a method for predicting the remaining life of an air filter. The method for predicting the remaining life of an air filter is applicable to predicting the remaining life of an air filter. The method can be determined by the remaining life of an air filter. Prediction device, the device can be implemented by means of software and / or hardware, and integrated in the vehicle, specifically, the method for predicting the remaining life of the air filter includes the following steps:

[0050] S110: Obtain the mass of particles filtered by the air filter within the current unit time.

[0051]When the air filter is used, it can filter out most of the particles in the air and allow enough clean air to enter the cylinder. The air filter can be used in the current environment for a period of time to count the air filter. the quality of the particles.

[0052] Specifically, acquiring the mass of particles filtered by...

Abstract

The invention relates to the technical field of air filters, and particularly discloses a method and a device for predicting residual life of an air filter and a storage medium. The method comprises the following steps of obtaining the mass of particles filtered by the air filter in the current unit time, the current front-back pressure difference of the air filter and the front-back pressure difference when the service life of the air filter is over; and determining the residual service life of the air filter based on the difference value between the front-back pressure difference when the service life of the air filter is over and the current front-back pressure difference and the mass of particles filtered in unit time, and accurately estimating the residual service life of the air filter.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to a method, device and storage medium for predicting the remaining life of an air filter. Background technique [0002] As an important part of the engine air intake filter system, the air filter can filter out most of the dust particles in the air and allow enough clean air to enter the cylinder. It performs multi-stage filtration of the air entering the cylinder of the diesel engine to ensure the quality of the air entering the cylinder of the diesel engine, reduce premature wear and strain of cylinder liners, pistons and other components, make the vehicle work normally in dust-prone areas, and prolong the use of diesel engines life. [0003] At present, the maintenance method of the air filter is still maintained in a relatively traditional way of regular replacement. One is to predict based on experience. For ordinary urban vehicles, the air filter is replaced every year o...
