Abstract

The present application relates to a particle catcher running-in method, device, computer equipment and storage medium. The method includes: controlling the electronic control unit to work according to the first data, keeping the speed of the vehicle at 0, making the temperature of the exhaust gas at the front end of the particle trap of the vehicle reach a preset temperature range for a first preset duration; controlling the electronic control unit Work according to the second data, run the vehicle, and control the vehicle to run at idle speed after the first particle filling; control the electronic control unit to work according to the first data, and run the vehicle according to the exhaust temperature of the front end of the particle catcher of the vehicle. After the second particle filling, control the vehicle to run at idle speed; control the electronic control unit to work according to the first data, keep the vehicle speed at 0, and make the front end exhaust temperature of the particle trap of the vehicle reach the preset temperature range and continue for the second preset temperature. Set duration. The method can ensure sufficient running-in of the particle catcher and improve the running-in efficiency of the particle catcher.

Description

technical field [0001] The present application relates to the technical field of automobile exhaust, in particular to a particle catcher 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 exhaust gas. There are stricter requirements for fine particulate matter (PM) limit value by 33%, and new limit value requirement for fine particulate matter number (PN) is added. [0003] To comply with regulations, most commercial vehicle plants place particulate filters (DPF) in the exhaust aftertreatment system. DPF forces the exhaust flow through the porous wall to absorb particulate matter in th...
