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.

Abstract

The invention discloses a vehicle exhaust particle capturing and regenerating device. The vehicle exhaust particle capturing and regenerating device comprises a particle capturing assembly, an air inlet pipe, a first exhaust pipe and a second exhaust pipe; the particle capturing assembly comprises a shell and a particle capturing device; an air inlet cavity is formed in the shell; a valve cover is arranged outside the shell; an air collecting cavity is formed in the valve cover; a first flow dividing opening and a second flow dividing opening are formed on the shell; a first elastic valve and a second elastic valve are arranged in the valve cover; a heating net is arranged on the particle capturing device; one end of the air inlet pipe is communicated with the air inlet cavity; one end of the first exhaust pipe is communicated with an air outlet of the particle capturing device; one end of the second exhaust pipe is communicated with the air collecting cavity; and air pressure can push the first elastic valve and / or the second elastic valve to be opened, so that the air inlet cavity is communicated with the air collecting cavity. The vehicle exhaust particle capturing and regenerating device can effectively avoid engine damage caused by the fault of the particle capturing device. The invention further relates to a vehicle exhaust particle capturing and regenerating method and a vehicle.

Description

technical field [0001] The invention relates to the technical field of engines, 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, the emission system of most current models uses a particle filter to capture incompletely burned carbon particles, and burns the captured particles in the heated particle filter. 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. Contents of the invention [0003] In view of this, the present invention provid...
