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 field of engine fittings, and in particular, to a vehicle exhaust particle regeneration and a method thereof, a vehicle.Background technique[0002]In order to meet the needs of Six emissions regulations, most of the models currently capture unsupported carbon particles using particulate pins, and burn the captured particulate matter at the heating particles. However, the particles need to increase the GPF temperature to burn the GPF temperature by additional input, if the GPF heating system is damaged, or the GPF itself is damaged, the particulate matter cannot be combusted in time, which will cause the engine that causes the pressure that is too high. Damage, the exemption, etc. during the driving process of the vehicle.Inventive content[0003]In view of this, the present invention provides a vehicle exhaust particle to regenerate the regeneration device without additional energy to realize the regeneration of the particle rej...
