Abstract

The invention discloses a catalyst sulfur poisoning treatment method and device, electronic equipment and a storage medium. The treatment method comprises the steps: detecting the differential pressure change rate of a particle catcher of a vehicle; if the pressure difference change rate of the particle catcher is greater than a preset change rate, controlling the upstream temperature of an oxidation catalyst of the vehicle to reach a specified temperature; controlling the quantitative post-injection quantity of the vehicle injection, and continuously detecting the upstream temperature of theparticle catcher; and if the maximum value of the upstream temperature of the particle catcher is not higher than the preset temperature, starting the post-injection of the vehicle, and returning to control the upstream temperature of the oxidation catalyst of the vehicle to reach the specified temperature after a preset time duration, until detecting that the maximum value of the upstream temperature of the particle catcher is higher than the preset temperature. Therefore, effective detection and timely detoxification treatment of catalyst sulfur poisoning of the oxidation catalyst are realized.

Description

technical field [0001] The present application relates to the technical field of vehicle post-treatment systems, in particular to a method and device for treating catalyst sulfur poisoning, electronic equipment, and a storage medium. Background technique [0002] With the gradual upgrade of emission regulations, after-treatment systems have become standard equipment for vehicles. Oxidation catalyst (DieselOxidation Catalyst, DOC) is one of the important components in the post-treatment system. It uses catalysts containing noble metals such as lead and platinum to oxidize carbon monoxide, hydrocarbons, nitrogen monoxide, etc. in the exhaust gas, reducing this part The content of the substance in the exhaust gas. [0003] However, the vehicle uses fuel with a high sulfur content, and the exhaust gas produced will lead to sulfur poisoning of the catalyst in the DOC, that is, the sulfur reacts with the noble metal in the catalyst, turning the noble metal into a sulfide, which d...
