Woluvo oksijini. Inkcazelo. ukuqashwa

An isivamvo oxygen xi okanye Lambda probe yenzelwe ukuqonda kwinqanaba zeemoto oksijini. Umsebenzi ngobuchule (loqoqosho kunye nokusingqongileyo) injini kuqinisekiswa kwinqanaba njalo umxube kwamafutha ratio lomoya kunye amafutha kuzo zonke iindlela zokusebenza. ulawulo Process umxholo oksijini iigesi zeemoto kuthiwa kumgaqo Lambda.

Kwimeko yokunqongophala emoyeni-fuel umxube womoya, akuthethi namava igcwala olupheleleyo carbon monoxide kunye hydrocarbon. Xa umoya supersaturation kwelinye icala, akukho yokubola epheleleyo mpilo kunye nitrogen.

Inkqubo exhaust ifakiwe Lambda probe. Kufuneka ke ukuba imifuziselo ezithile yeemoto ezisetyenziswayo isivamvo ioksijini ngaphezu kwesinye, kodwa ababini. Kulo mzekelo, enye iseti ye converter zokuphosa, kunye nezinye - emva kwayo. Ukusebenzisa izixhobo ezimbini uphucula ulawulo phezu nokwakhiwa zegesi zeemoto kunye nokuqinisekisa ukusebenza isebenzayo ye neutralizer.

Le woluvo oxygen inokuba ingongoma-ezimbini okanye lwebhendi ebanzi.

Onesethi yokuqala, yaye emva kuvala, yaye phambi kwakhe. Ingongoma-ezimbini ukulungiswa womenzi woluvo oxygen inika amafutha womoya umxube ratio lomoya kwemfuneko ngokungqinelana kunye nexabiso uyondelelwano lwee- oksijini iigesi zeemoto.

Uyilo thaca ngokohlobo into yodongwe ene-ukutyabeka-kabini ezimbini zirconium dioxide. isivamvo oxygen check lwenziwa yi indlela electrochemical. On electrode elinye-icala wadibana yeegesi zeemoto. Kwelinye icala - kunye emoyeni. Iphumelele isiqulatho oksijini ombane eveliswa eziphelweni electrode. Inqanaba eliphezulu (ingqalelo umxube kwamafutha ndayame), lo ombane usezantsi. Ngako oko, le ndzo ephakamileyo (ingqalelo umxube zizityebi), lo ombane enkulu.

Le woluvo oxygen ithumela yimitha yombane ukuya unit ulawulo electronic kwinkqubo yolawulo motor. Ngokungqinelana kwinqanaba uphawu lo, ukuba sesichengeni yenzelwa phezu ubume actuators kwiinkqubo imoto leyo aphantsi kolawulo unit yolawulo.

isivamvo Ulwakhiwo broadband amelwe njengelungu point-ezibini sokumpompa. Ukumiselwa kwe "Lambda" lwenziwa ukusetyenziswa ngoku xa zokumpompa. Isetyenziswa njengento isixhobo sokufaka yi woluvo ioksijini ukuba converter encedisa ukuqalisa imisebenzi. Ngokumpompa ukuqonda inkqubo engokoqobo. Ngexesha Inaliti ze gesi oxygen udlula i element ezimpontshelwa phantsi kwempembelelo le yangoku. Umgaqo apho ifowuni isebenza, ngokusekelwe uyakwazi ukugcina rhoqo kwi lombane 450 MV e isiqalelo point-mbini phakathi electrode ngenxa utshintsho xa efaka yangoku.

Ukwehlisa umxholo ioksijini yeegesi (kunye nomxube fuel usisityebi) sikhatshwa ukwanda ombane phakathi ezikhoyo esimanqaku ezimbini electrode element ceramic. Signal sifakwa ukusuka element kwicandelo control elektroniki. Ngokusekelwe kwi yangoku umqondiso eziveliswa Impontshelwa element nomkhosi ethile.

Naye, igalelo isitofu wangoku ethubeni yokulinganisa. Ngaloo ndlela ombane ufikelela ixabiso ethile. Xa eli candelo yangoku ngumlinganiselo ioksijini yoxinaniso igesi. Uhlahlelo kunye nokuguqulwa ibe nezenzo zolawulo ngeyunithi abulawe indlela kwinkqubo isitofu lwenziwa licandelo lolawulo.

In engamarhoqorhoqo, intsebenziswano isixhobo lwebhendi ebanzi kwenzeka ngokufanayo. Umahluko kukuba inomlinganiselo umsantsa phantsi kwempembelelo ukumpontshwa yangoku yenziwa oksijini.
