The kind of various harmful gass in vehicle exhaust is determined according to absorbed ultrared wave-length coverage and absorbed degree
And content.
It is each owing to vehicle exhaust having generally comprised carbon monoxide, Hydrocarbon, oxygen sulfur compound, oxynitride etc.
Plant harmful gas.And every kind of gas has specific characteristic absorption band and characteristic frequency in these gases, when infrared spectrum falls
Can be by strong absorption when of near characteristic frequency band.So tail can be detected by the infrared spectrum of individual features frequency
The composition of harmful gas in gas, and the amount of absorbed external spectrum can detect kind and the content of corresponding gas.
Step S102, kind and content according to described harmful gas judge whether the carbon monoxide in vehicle exhaust exceedes
First threshold.If then performing step S103.Otherwise return execution step S101 and proceed tail gas monitoring.
Step S103, if the judged result of step S102 is yes, then obtains automobile current driving speed, and at described automobile
When current driving speed is less than Second Threshold, send instruction by automobile electric control system, control all automobile side-windows and close, and from
Move and open air conditioning for automobiles and vehicle dormer window.
In the embodiment of the present invention, when carbon monoxide exceeds standard, by obtain automobile current driving speed judge be currently
No being in traffic congestion state, it is contemplated that under traffic congestion state, passenger's side window that typically can select to call a taxi, to observe traffic environment, now spreads
Aerial vehicle exhaust is very likely entered in automobile bodies by automobile side-window, thus pollutes vehicle environment；Therefore this
Inventive embodiments presets threshold value, automobile current driving speed less than Second Threshold time, by automobile electric control system (or
Automobile middle control platform) control all automobile side-windows and be automatically switched off, prevent the vehicle exhaust in air from being entered by automobile side-window
Automobile bodies；Automatically open up air conditioning for automobiles and vehicle dormer window simultaneously, on the one hand discharge the harmful gas in original compartment, on the other hand
Filter out a large amount of harmful gas by the powerful purification function of air conditioning for automobiles, allow clean air enter in automobile bodies.
Step S104, opens automobile the second depurator valve, and described motor vehicle exhaust emission is clean to described automobile second
Change device and carry out carbon monoxide process, wherein, in described automobile the second depurator, be filled with absorbent for carbon monooxide.
In compartment of draining after carbon monoxide, it is contemplated that air still can exist tail gas, therefore to ensure passenger
Safety and protection environment, in addition it is also necessary to from root reduce fly away the vehicle exhaust in compartment.In the embodiment of the present invention, automobile
Second depurator is the device being specifically used to carry out the various harmful gass in vehicle exhaust double absorption process, and it can
In place of being connected to automobile exhaust purifier outlet.Concrete, absorbents of carbon monoxide can be by porous inorganic carrier and its
On the compositions that constitutes of the two-element match of the nitride that is loaded with and copper chloride；Described inorganic carrier includes: ceramic honey comb, work
Property charcoal or titanium oxide etc.；Described nitride be pyridine and's
Compositions.
As a preferable embodiment, in described compositions, nitride can account for 0.32-0.69 mol ratio.
As preferred embodiment, described acquisition to the exhaust pressure value step in automobile engine exhaust pipe exit it
After, it is also possible to comprise the following steps:
Obtain the exhaust pressure value in automobile engine exhaust pipe exit；
Calculate described exhaust pressure value in the given time more than or equal to the actual frequency of predetermined value；
Judge that whether described actual frequency is more than or equal to the 3rd threshold value；
The most then send and extend the time delay command opening described automobile the second depurator valve；
The opening time of described automobile the second depurator valve is controlled according to described time delay command, and in this opening time
Stop obtaining the exhaust pressure value in automobile engine exhaust pipe exit.
In the embodiment of the present invention, when the most described exhaust pressure value is more than or equal to the reality of described predetermined value
When number of times reaches three threshold value set, the most automatically judge that the road conditions of the traveling of automobile are more complicated, such as upward slope etc., at this time
Passenger in compartment, by the maximum probability of automobile exhaust pollution, now can extend when opening of automobile the second depurator valve
Between, such as extend to 5 minutes or 10 minutes.This time opened can be set in advance, and the concrete process set can
Using prior art, it will not go into details herein.In like manner, the described scheduled time, predetermined value, first threshold, Second Threshold, the 3rd threshold value
Deng all similar means being used according to actual needs to be set.
As a preferable embodiment, control opening of described automobile the second depurator valve according to described time delay command
The process of time specifically may include steps of:
Extract the time value in described time delay command；This time value is to show that described actual frequency is more than or equal in judgement
After 4th threshold value, according to exhaust pressure value, actual frequency value and automobile current driving speed these three parameter according to predetermined
Formula automatically generates after calculating and is encoded in time delay command, concrete, described time value and described exhaust pressure value
And described actual frequency is proportional, and with described automobile current driving speed inversely；
After opening described automobile the second depurator valve, open an intervalometer, arrive the described time at this intervalometer
Described automobile the second depurator valve is closed during value.
It addition, as a preferable embodiment, by the mistake of described motor vehicle exhaust emission to described automobile the second depurator
Journey specifically may include steps of:

Calculate with reference to speed according to temperature, exhaust pressure value and CO meter in rotating speed, automobile the second depurator
Degree, and regulate the motor vehicle exhaust emission speed to described automobile the second depurator according to described reference velocity.
In the present embodiment, equation below can be used to calculate reference velocity:
In above formula, V is reference velocity；R is the rotating speed of automobile engine, and C is carbon monoxide content, and T is that automobile second is clean
Changing temperature in device, P is exhaust pressure value, and a is constant conversion coefficient, between 0.38-0.64.Arrive by controlling exhaust emissions
In automobile the second depurator speed so that carbon monoxide can be absorbed in automobile the second depurator more completely, from
And the efficiency that carbon monoxide processes can be effectively improved, so enter into the carbon monoxide in automobile bodies and naturally also just reduce
?.Particularly, proving through substantial amounts of experimental data, when the value of a is taken as 0.46, the absorbed efficiency of carbon monoxide is optimal.
By above scheme it can be seen that carbon monoxide processing method in the automobile bodies of the embodiment of the present invention, pass through
Vehicle exhaust is detected by the mode of infrared detection, and according to the kind of harmful gas and content, automobile current driving speed
Degree judges whether need closing automobile side window and open air conditioning for automobiles and vehicle dormer window, simultaneously by motor vehicle exhaust emission to automobile
Second depurator carries out carbon monoxide process, thus spreads in automobile bodies when decreasing automobile traffic congestion from source
Carbonoxide, has ensured the physical safety of passenger in compartment.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection domain of the claims in the present invention
Within.
