Vehicle exhaust particulate filtering and regenerating device and method and vehicle

Abstract

The invention discloses a vehicle exhaust particulate filtering and regenerating device. A particulate filter is provided with a heating net, one end of an air inlet pipe is connected with an air source, the other end of the air inlet pipe is connected with an air inlet of the particulate filter, one end of a first exhaust pipe is connected with an air outlet of the particulate filter, a first exhaust valve is arranged in the first exhaust pipe, a first mounting hole, a second mounting hole and a third mounting hole are formed in the first exhaust pipe, the two ends of the second exhaust pipe are connected with the first mounting hole and the second mounting hole respectively, a generator is connected to the second exhaust pipe and electrically connected with the heating net, a fourth mounting hole is formed in the air inlet pipe, the two ends of the third exhaust pipe are connected with the third mounting hole and the fourth mounting hole respectively, a second exhaust valve is arranged in the third exhaust pipe, and a control system can control the first exhaust valve and the second exhaust valve to be opened or closed. According to the vehicle exhaust particulate filtering and regenerating device, regeneration can be achieved without extra energy. The invention further relates to a vehicle exhaust particulate filtering and regenerating method and a vehicle.

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...
