Problems solved by technology

However, after the particles are captured, it is necessary to increase the temperature of the GPF through an additional input power supply to burn off the particles. At the same time, if the GPF heating system is damaged, or the GPF itself is damaged, the particles cannot be burned in time, which will lead to excessive pressure and poor airflow, which will cause the engine damage, flameout while the vehicle is in motion, etc.

Description

technical field [0001] The present invention relates to the technical field of engine accessories, in particular to a vehicle exhaust particle collection and regeneration device, a method thereof, and a vehicle. Background technique [0002] In order to meet the requirements of the National VI emission regulations, most of the current vehicle emission systems use a particle collector to capture insufficiently burned carbon particles, and the captured particulate matter is burned in a heated particle collector. However, after the particles are captured, the temperature of the GPF needs to be increased by an additional input power supply to burn the particles. At the same time, if the GPF heating system is damaged, or the GPF itself is damaged, the particles cannot be burned in time, which will lead to excessive pressure and poor airflow. Danger of damage, stalling of the vehicle while driving, etc. SUMMARY OF THE INVENTION [0003] In view of this, the present invention pr...
