Improve the temperature of driver's cabin or rear row seat bottom, avoid in winter rider foot suffer from cold, while can also reduce tail gas
The temperature of discharge is conducive to environmental protection, and then filtered particle can be retained in filter core 5 by tail gas through filtration core 5
Side, tail gas is discharged in the effect of activated carbon case 6 under the catalysis of catalytic unit 7 later, while tail gas again passes by heat-exchanging water tank
It further exchanges heat, detection device 9 passes through its internal NOx sensor 902, carbon monoxide transducer 903 and temperature
Degree sensor 904 to after treatment tail gas content and temperature be detected, and will be detected by transmission module 905
As a result it is transferred in mobile device, can effectively control the quality of exhaust emissions.
The embodiment of the present invention provides for the sake of example and description, and is not exhaustively or by this to send out
It is bright to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Choosing
It is and to make those skilled in the art to more preferably illustrate the principle of the present invention and practical application to select and describe embodiment
It will be appreciated that various embodiments with various modifications of the present invention to design suitable for special-purpose.
