Abstract

The invention relates to a particle catcher running-in method and device, computer equipment and a storage medium. The method comprises the steps that an electronic control unit is controlled to work according to first data, the speed of a vehicle is kept to be 0, and the front end exhaust temperature of a particle catcher of the vehicle reaches a preset temperature range and lasts for a first preset duration; the electronic control unit is controlled to work according to second data, the vehicle runs, and the vehicle is controlled to run at an idle speed after the first particle filling; the electronic control unit is controlled to work according to the first data, the vehicle runs according to the front end exhaust temperature of the particle catcher of the vehicle, and the vehicle is controlled to run at the idle speed after the second particle filling; and the electronic control unit is controlled to work according to the first data, the speed of the vehicle is kept to be 0, and the front end exhaust temperature of the particle catcher of the vehicle reaches the preset temperature range and lasts for a second preset duration. By adopting the method, sufficient running-in of the particle catcher can be ensured, and the running-in efficiency of the particle catcher is improved.

Description

technical field [0001] The present application relates to the technical field of automobile exhaust, and in particular, to a particle trap running-in method, device, computer equipment and storage medium. Background technique [0002] Since the Ministry of Ecology and Environment and the State Administration for Market Regulation jointly issued the "GB 17691-2018 Heavy-duty Diesel Vehicle Pollutant Emission Limits and Measurement Methods (China Phase VI)", the National VI emission regulations are more effective than the National V emission regulations on particulate emissions in the exhaust. There are stricter requirements for fine particulate matter (PM) by 33%, and a new limit on fine particulate matter (PN) is added. [0003] In order to meet regulations, most commercial vehicle manufacturers have installed particle traps (DPFs) in their exhaust aftertreatment systems. DPF forces the exhaust flow through the porous wall to adsorb particulate matter in the exhaust, which ...
