Abstract

The invention relates to the technical field of automobile reliability testing, and discloses a testing method and equipment for an automobile exhaust device, a storage medium and a device. The methodcomprises the following steps: acquiring content information of experimental sulfur flowing through an automobile exhaust device in a unit sulfur-resistant period in an automobile experimental platform; comparing the experimental sulfur content information with target sulfur content information, and adjusting the content of a sulfur additive in the automobile exhaust device according to a comparison result to obtain experimental sulfur additive content information; and carrying out a sulfur resistance test on the automobile exhaust device according to the experimental sulfur additive contentinformation, so that the experimental sulfur content information in the automobile experimental platform can reach the optimal sulfur content by adjusting the sulfur additive content in the automobileexhaust device, and the flexibility of realizing the reliability of an aftertreatment system is improved.

Description

technical field [0001] The invention relates to the technical field of automobile reliability testing, in particular to a testing method, equipment, storage medium and device for an automobile exhaust device. Background technique [0002] With the upgrading of emission regulations, the requirements for the purification ability of the engine outside the machine are getting higher and higher, and the after-treatment system of the car must be adaptively upgraded or changed accordingly. At the same time, the introduction of the emission warranty period further increases the reliability requirements for the after-treatment system. NOx Storage Catalyst (NSC) is an aftertreatment device that reduces engine NOx emissions by periodically adsorbing and desorbing NOx. Its core component is BaCO3. While adsorbing NOx, it also adsorbs SO2 and SO3 in the exhaust gas convert BaCO3 into BaSO4, reducing the conversion ability of NSC. Therefore, NSC needs to be desulfurized regularly. Desulf...
