Specific embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.In the following description, there is provided the specific detail of such as specific configuration and component is only
Only to assist in comprehensive understanding embodiment of the present utility model.Therefore, it will be apparent to those skilled in the art that can be to here
The embodiment of description is made various changes and modifications without deviating from scope and spirit of the present utility model.In addition, in order to clear and
Succinctly, the description to known function and construction is eliminated.
With reference to Fig. 1, this utility model embodiment provides a kind of engine exhaust system, including：With the aerofluxuss of electromotor 1
The ternary catalyzing unit 2 of manifold connection；The acoustic filter 3 being connected by pipeline with the ternary catalyzing unit 2；It is arranged at the ternary to urge
Change the exhaust blower 4 between device 2 and the acoustic filter 3, the exhaust blower 4 is connected by a belt pulley 5 with the electromotor 1, institute
The blade 41 for stating exhaust blower 4 is arranged at the channel interior, and the electromotor 1 drives the exhaust blower 4 by the belt pulley 5
Blade 41 rotate；The exhaust blower clutch 6 being connected with the belt pulley 5 and the exhaust blower 4 respectively；Controller 7, respectively with
The electromotor 4 and the exhaust blower clutch 6 connect, according to the real-time working condition of the electromotor 1, control the exhaust blower from
