Abstract

The invention discloses a carbon carrying capacity detection method, equipment, a storage medium and a device. The actual pressure difference value of an inlet and an outlet of a gasoline engine particulate filter GPF and the current exhaust flow of an engine are firstly acquired, the model pressure difference value is calculated according to the current exhaust flow, pressure drop of the GPF is obtained according to the actual pressure difference value and the model pressure difference value, the pressure difference index is obtained according to the pressure drop and a preset pressure drop and pressure difference index model, pressure difference conversion and calibration are carried out according to the pressure difference index, and the carbon carrying capacity of the GPF is obtained.A carbon carrying capacity model cannot accurately and stably acquire the carbon carrying capacity in the prior art, by means of the method, the pressure difference index is obtained through the pressure drop relation of the actual pressure difference value and the model pressure difference value, the carbon carrying capacity of the GPF is further obtained, and therefore a GPF carbon carrying capacity estimation and calculation model can accurately and stably acquire the carbon carrying capacity in the GPF.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a carbon load detection method, equipment, storage medium and device. Background technique [0002] With the continuous growth of car ownership, vehicle exhaust emissions have brought more and more pressure on the environment, among which particulate matter (PM) emissions from gasoline engines are an important part of pollutants. With China's Ministry of Environmental Protection promulgating the National Phase VI emission regulations, the emission limits for particulate matter have become more stringent. The use of gasoline engine particulate filter GPF can effectively reduce particulate matter emissions, and has been widely used in six engine platform projects in various countries. [0003] Since the particles of gasoline engines are smaller and lower than those of diesel engines, high requirements are placed on the accuracy of the carbon load model of particle traps. An i...
