Indlela yokujonga i-catalyst for clogging: imiyalelo yesinyathelo ngesinyathelo, isixhobo kunye neziphakamiso

Unyaka wonke, ihlabathi liqinisa imigangatho yokusingqongileyo. Okwangoku, kumazwe aseYurophu, iimoto ezinokutshatyalaliswa okungenani "i-Euro-4" zisetyenziselwa. E-Rashiya, ubunzima obuncinane bokungqinelana kokusingqongileyo kweegesi zokukhupha. Nangona kunjalo, kwanamhlanje "iLada" kunye ne "GAZ" zixhotyiswe ngefowuni njengesixhobo sokwenza izinto. Yintoni le nto? Usebenza njani? Ungaqwalasela njani ukunikezelwa kwe-catalyst? Ngokuphathelele konke oku kwaye kungekhona kuphela - kamva kwinqaku lethu.

Isici

Ngoko, yiyiphi inzuzo? Eli nqanaba linye yeenxalenye zenkqubo yokukhupha. I-catalyst ikhona phambi kombhobho, emva kombhobho wokungena (ukuba kukho i-resonator kwimoto, phambi kwayo). Igama elipheleleyo le fowuni ngumguquleli oguqula. Yintoni eyenzayo? Esi sixhobo senzelwe ukunciphisa ubunobunzima bokukhupha iigesi. Ngaloo ndlela, i-catalyst iyatshisa izinto ezinobungozi, zibathintele ukungena emoyeni. Ukukhathala kuya kuba yicocekile kwaye kungabonakali kakhulu kwimeko.

Ukwakhiwa

Makhe sijonge kwi sixhobo se-catalyst. Esi sigaba sineziqendu eziliqela:

• IiShells.
• Ibhulothi.
• Ukutshatyalaliswa kwamafutha.

Konke kusebenza njani? Into ebalulekileyo yiphina into eyenza i-catalyst iyunithi yokuphatha. Yenziwe ngeekeramics. Le ngxenye ebiza kakhulu kwi-neutralizer. Ngaphakathi kwento (ephambili) kukho ezininzi zeeseli-cell, ozozibona kwisithombe esingezantsi. Ngoko i-catalyst ikhangeleka. Ukuphuma kwegesi kudlula kule mihla. Ndiyabulela kubo, indawo yokudibanisa neegesi kunye nezinto ezinokukhushulwa ziyanda kakhulu. Uluhlu olulandelayo luyi-thermal insulation, eyanciphisa ukulahleka kobushushu ngaphakathi kweso sixhobo. Emva koko, izinto eziyingozi kufuneka zitshintshwe, kwaye ngenxa yoko kubalulekile ukuba kufinyelele kwiqondo eliphezulu lokushisa kwi-core ceramic. Kwaye, ekugqibeleni, konke oku kufakwe kwimeko yensimbi. Yomelele ngokwaneleyo, ngoko akunakwenzeka ukuyitshisa njenge-silencer. Ukongezelela, kukho uluhlu lwe-thermal insulation.

Usebenza njani?

Iimigesi, zidlula ngaphaya kwe-catalyst, zihlambulule izinto eziyingozi? Kulula kakhulu. Ngaphakathi kwinqanaba le-ceramic kukho izinto ezinokwenza izinto. Le palladium ne-platinum, kunye ne-rhodium. Ezi zinto zifaka isandla ekukhawulezeni kweempendulo zamakhemikhali. Ngaloo ndlela, i-carbon dioxide engatshitshisiyo iguqulwe ibe yi-carbon dioxide, kunye ne-hydrocarbons ibe ngumphunga wamanzi.

Ukusebenza kwe-catalyst kufezekiswa kuphela phantsi kweemeko zamanzi aphezulu, aphantsi kwama-degrees Celsius angama-400. Yingakho isixhobo sisekho nje emva kokufunwa kwezinto ezininzi. Nangona kunjalo, akunakwenzeka ukuba ufikelele kubushushu obunjalo, ngakumbi ebusika ekuqaleni. Ngako oko, inxalenye yokukhupha ingacocwanga, kwaye idlula kwi-cleaner "engenzi lutho".

Ukwandisa ukusebenza kakuhle nokukhawulezisa iinkqubo zeekhemikhali, kufuneka uhlale ushushu obuphezulu kwi-catalyst. Oku kungafezwa njani? Ngenxa yale njongo, i- oxygen sensor efakwe kwisixhobo . Ifunda ulwazi olufunekayo malunga nokukhupha, ize idlulisele umqondiso kwiyunithi yokulawula. Kwaye sele sele ivela kwi-ECU ifika umqondiso kwiintlobo ezininzi zokutya, apho ukuhlanganiswa komxube womoya oguquka. Ngenxa yohlengahlengiso, i-elektroniki ngokuzenzekelayo igcina ukushisa okufunayo ngaphakathi kwintsebenziswano. Ngenxa yokucebisa umxube womoya, ukufudumala kwezi zinto kwanda.

Ungajonga njani i-catalyst ngaphandle kokukususa? Indlela yokuqala

Nayiphi na i-neutralizer yenzelwe ixesha elithile lokusebenza. Ngokuqhelekileyo ezi zixhobo zikhonza iikhilomitha eziliwaka ezingama-200. Ekupheleni kweli xesha, inani elaneleyo lezinto ezingenasidingo ziqokelele ngaphakathi kwinqanaba, elilivala. Uyakujonga njani umxube kumatshini ngaphandle kokususa? Oku kungagqitywa ngobungqina obuchanekileyo:

• Imoto iqala ukugqithisa imali.
• Iphosa liphela.
• Kukho iphunga elimnandi lika-hydrogen sulfide.
• Ukuqala kanzima kwenjini. Kwaye oku kwenzeka nangona "kushushu". Isizathu salesi si-catalyst ekhutshiwe. Ukukhupha i-gesi kunzima ukunqoba i-mesh ecocekileyo.

Zonke ezi zimpawu zihamba kunye nesibane esilumkiso esiluhlaza kwipaneli yecandelo. Ubonakala ngathi umfanekiso olapha. Ukuba i- CHECK ikhanyisa kwipaneli yecandelo , kwaye ukuziphatha kweemoto kuye kwatshintsha ngakumbi, le sizathu sokuba sicinge nge-catalyst clogging.

Kutheni oku kwenzekayo?

Kukho izizathu ezimbalwa zeli ganeko. Oku kukutshatyalaliswa kwendawo engundoqo okanye i-ceramic okanye i-carbon black. Kwakhona, iimeko apho iiseli zokuchukumisa zitshatyathwa aziqhelekanga. Kwinqanaba le ngxaki ibonakala ngale ndlela. Oku kuthetha ukuba inxalenye ivalwe, kwaye kufuneka ifakwe endaweni. Iimpawu ezifanayo zinokuthi zenzeke kwiinjini ze-dizeli, apho i- filter filter isetyenziselwa endaweni ye-catalyst . Musa ukuyihoxisa le mpawu.

Uyakujonga njani u-catalyst for clogging? Indlela yenombolo 2 - i-manometer

Ingundoqo yile ndlela ukujonga inkqubo yokukhupha i-back pressure. Uyakujonga njani u-catalyst for clogging? Kule nto sidinga i-manometer kunye ne-adapter. Umva wokugqibela kufuneka ube nobubanzi obunokuthi ungene kwindawo ye-oxygen sensor. Ngoko ke, siyiphonononga isondlo se-lambda kwaye sifaka i-gauge ye-pressure nge-adapter apho. Ukujonga njani i-catalyst? Siqala injini, sikhulise iinguqulelo kwi-2.5,000 kwaye sijonge ukufundwa. Uxinzelelo oluqhelekileyo kufuneka ubuncinane libe ngu-0.34 kgf nganye ngecentimitha yesikwere. Ukuba umgangatho ungaphantsi, ngoko umgangatho uvalwe.

Ngale ndlela, unokujonga i-VAZ 2170 okanye i-car engaphandle. Ingxaki kuphela yinkxalabo yokudiliza i-oxygen sensor. Ngokuqhelekileyo, "inamathela" kwi-catalyst. Kwakhona kuyimfuneko ukufezekisa ubungqina obuninzi bomdibaniselwano. Ukuba ukucima "ukucima", ubungqina buya kuchaneka.

Indlela yesithathu ngumhloli weemoto

Ndingayiqwalasela njani ukuba i-catalyst ishiyiwe? Ungasebenzisa umhloli weemoto. Ngenxa yale njongo, endaweni yesiplagi se-spark, i-sensor control ifakiwe, elungisa ingcinezelo kwinkqubo. Ukuqhubela phambili kwikhompyutha i-oscillogram isusiwe, ngesiseko apho isiphetho malunga nokunikwa kwe-catalyst ithathwa. Le ndlela ichanekile, kodwa akusiyo wonke umntu unomhloli womqhubi kwizandla zawo. Ngokuqhelekileyo le nkonzo inokuyalelwa kwiitishi ezizodwa zenkonzo.

Indlela yesine ukuhlolwa kokubonakalayo

Ungazijonga njani ukuzenzekelayo? Le ndlela ifumaneka kuwo wonke umntu, kodwa ngokukhawuleza siqaphele ukungalungi kwayo. Ngokuqinisekileyo uya kuba nobunzima ekuphazamiseni into. Ngokuqhelekileyo ii-bolts zixinyiwe "zibilisiwe", kwaye zinokunqunyulwa kuphela yiBulgaria. Ewe, unokuzifaka endaweni yazo. Kodwa le yongeza imali. Ngokususa iqela, uya kubona imeko yeseli yeseli. Ukuba kukho ukulandelwa kokuhlaziywa komhlaba, olo hlobo luyasetyenziswa. Ngokuqhelekileyo, esikhundleni salo, ukufakela isikhala esivamile okanye ukugcinwa komlilo kufakwe. Ekubeni isalathisi iqulethe ixabiso lexabiso eliphezulu ngaphakathi, ixabiso layo livela kwi-$ 500. Indlela ephantsi kakhulu ukufaka umnqamli womlilo kunye ne-computerware firmware. Kwibhloko, into yokucoca iyanqunyulwa, ukuze i-CHECK yobhaliso ingabonakali kwiphaneli kwikamva.

Isiphelo

Ngoko, safumanisa indlela yokujonga isithintelo ngezandla zethu, indlela le nto isebenza ngayo kwaye isebenza ngayo. Khangela i-odometer ukufunda nokuphulaphula imoto. Ukuba imoto imdala, qiniseka ukuba ususe i-catalyst - imoto iya kuba lula "ukuphefumula".
