Indlela yokuhlola i-catalyst?
Uma imoto ima ukusheshisa ngokujwayelekile noma ukukhanya kwe-Check Engine kuyakhanya, kuzodingeka ukuhlolwa kwe-catalytic converter. Ingakwazi ukuvala noma ukudilika ngokuphelele ikhekheba lezinyosi. i-bobbin ingase yonakale. Ukuze uhlole i-catalyst, ungayisusa ngokuphelele noma usebenzise indlela ngaphandle kokuyisusa. Ubunzima bale ndlela bulele eqinisweni lokuthi udinga umsizi ukuze asebenze ne-gauge yokucindezela, awukwazi ukubhekana nakho ngokwakho.
Izizathu Zokususwa Kwe-Catalyst
Ezinkingeni zokuqala ekusebenzeni kwe-catalyst, abanikazi bezimoto ezisetshenzisiwe bacabanga ngokususa lesi sici. Kungase kube nezizathu eziningana zalokhu.
Izizathu zokuthi kungani abaningi besusa ama-catalysts:
abanye basikisela ukuthi i-catalyst ingase yehluleke ngesikhathi esingafanele;
owesibili ucabanga ukuthi uphethiloli wasekhaya ushaywe kabi, awuvumeli injini evuthayo yangaphakathi ukuba "iphefumule ngokujulile";
abanye bakholelwa ukuthi uma ususa ukumelana okweqile endaweni, ungathola ukwenyuka kwamandla e-ICE, kanye nokunciphisa ukusetshenziswa kukaphethiloli.
Kodwa, ngeshwa, iningi labashayeli abagibele ngaphansi kwe-hood nge-crowbar babhekene nokumangala okungajabulisi - futhi lena i-ECU (iyunithi yokulawula i-ICE). leli bhulokhi lizobona ukuthi azikho izinguquko kumagesi okukhipha amandla ngaphambi nangemva kwe-catalyst futhi izokhipha iphutha.
Kungenzeka ukukhohlisa i-block, kodwa futhi ungayikhanyisa kabusha (le ndlela ngeke ikhulunywe kulokhu okuqukethwe). Esimweni ngasinye, kunendlela (lezi zinkinga kuxoxwa ngazo ezinkundleni zokuxhumana).
Ake sicabangele impande yobubi - isimo "katalik". KODWA kufanele isuswe? Iningi labashayeli bezimoto liqondiswa imizwa yabo: imoto yaqala ukudonsa kabi, "Ngiyaqiniseka ukuthi i-catalyst ivalekile futhi iyimbangela," njll. Ngeke ngikholise abanenkani, kodwa abahlakaniphile baqhubeke nokufunda. Ngakho-ke, konke okudingeka ukwenze ukuhlola isimo se-catalyst, futhi ngokusekelwe esimweni saso, sizophetha ngokuthi idinga ukususwa noma ukushintshwa, kodwa ngokuvamile zisuswa ngenxa yezindleko zabo.
Hlola i-catalyst
Ukuhlolwa kwe-catalyst yokususa nokuvala
Ngakho-ke, kwaphakama umbuzo, "Indlela yokuhlola i-catalyst?". Indlela ephumelela kakhulu futhi elula ukuqaqa i-catalyst bese uyihlola. Uma kutholakala umonakalo omkhulu, i-catalyst ingalungiswa.
Sisusa i-catalyst futhi sibheke isimo samaseli sisonke - ukuvinjelwa kwamaseli kungahlolwa ukuze kutholakale imvume, futhi ngenxa yalokhu umthombo wokukhanya uyasiza. Kodwa akuyona yonke into elula njengoba kubonakala. Ngezinye izikhathi, ngesikhathi sokusetshenziswa isikhathi eside, i-catalyst mount inamathela kakhulu Ukususa i-catalyst kungaphenduka umsebenzi omude nojabulisayo. (Mina ngokwami ngikhulule amantongomane amabili angemuva okubopha amahora angu-3, ekugcineni akusebenzanga - kwadingeka ngiwanqume phakathi!). Umsebenzi awunzima kakhulu, ngoba udinga ukusebenza ngaphansi kwemoto.
Izimpawu eziyinhloko nezindlela zokuhlola i-catalyst ukuthi ayivalekile
Zikhona kunezindlela eziningana zokuhlola i-catalyst:
- kungenzeka ukukala ukuphuma kokuqukethwe kwezinto eziyingozi (nge-catalyst engalungile, okuqukethwe kwezinto eziyingozi kukhuphuka kakhulu uma kuqhathaniswa ne-catalyst esebenzayo);
- ungaphinda uhlole ingcindezi yangemuva endaweni yokuphuma (uphawu lwe-catalyst evalekile luyanda ukumelana futhi, ngenxa yalokho, ingcindezi).
Ukuze uhlole inhloso yombuso, udinga ukuhlanganisa zombili lezi zindlela.
Ihlola i-catalyst ye-back pressure
Ukuhlolwa kwengcindezi yasemuva
Okulandelayo kuchaza indlela yokuhlola isimo se-catalyst ngokumelene nokucindezela okukhiqizwa emuva.
Ukuze wenze lokhu, phambi kwe-catalyst, kuyadingeka ukushisela ukufakwa kwesampula ukuze uthole isampula yokukhipha amagesi. Kunconywa ukushisela ukufakwa ngentambo kanye nesimo sesiteshi, lezi zifakelo zifana nokufakwa kwamapayipi amabhuleki. Ngemuva kokuthi izilinganiso seziqediwe, amapulaki ashunqulwa kulezi zilinganiso.
Izinqamuli okungcono yenziwe ngethusi - lokhu kuzobahlinzeka ngokukhulula mahhala ngesikhathi sokusebenza. Ukuze uthole izilinganiso, ipayipi yebhuleki engu-400-500 mm ubude kufanele ifakwe ekufakeni, umsebenzi wawo ukuqeda ukushisa okukhulu. Sifaka ipayipi yerabha ekugcineni kwamahhala weshubhu, sixhuma i-gauge yokucindezela ku-hose, ububanzi bayo bokulinganisa kufanele bufike ku-1 kg / cm3.
Umfutho ongemuva ungakalwa ngenkathi imoto ishesha nge-throttle evuleke kakhulu. Ukucindezela kunqunywa igeji yokucindezela ngesikhathi sokusheshisa, ngokukhuphuka kwejubane, wonke amanani aqoshiwe. Esimeni lapho amanani okucindezela emuva ngesikhathi sokusebenza nge-damper evulekile ngokugcwele kunoma yiluphi uhla lwejubane edlula u-0,35 kg / cm3, lokhu kusho ukuthi uhlelo lokukhipha umoya ludinga ukuthuthukiswa.
Le ndlela yokuhlola i-catalyst iyafiseleka, noma kunjalo, empilweni yangempela, ukufakwa kwe-welding kuyibhizinisi elinodaka. Ngakho-ke, ngenze lokhu: Ngakhulula i-lambda emi phambi kwe-catalyst ngase ngifaka igeji yokucindezela nge-adaptha. (Kutuswa ukusebenzisa i-gauge yokucindezela ngokunembe kuze kufike ku-1 kg / cm3).
Njenge-adaptha, ngasebenzisa i-hose yerabha, engalungisa usayizi ngommese (ungakhohlwa ukuthi ukuqina kubalulekile).
Lena indlela ithuluzi lesevisi elisebenza ngayo elibukeka ngayo
USam wamkala ngepayipi.
Ngakho:
- Siqala injini yomlilo yangaphakathi futhi sibheke ukufundwa kwegeji yokucindezela (lokhu ukucindezela okungemuva endaweni yokuphuma).
- Sibeka umsizi ngemuva kwesondo, ukhuphula ijubane ku-3000, sithatha ukufundwa.
- Umsizi uphinde uphakamise ijubane, kodwa kakade kuze kufike ku-5000, sithatha ukufundwa.
I-ICE ayidingi ukusonteka! 5-7 imizuzwana kwanele. Akudingekile ukusebenzisa i-gauge yengcindezi efinyelela ku-3 kg / cm3, njengoba ingase ingakuzwa ngisho nokucindezela. Igeji yengcindezi ephezulu ingu-2kg/cm3, ingcono kuno-0,5 (uma kungenjalo iphutha lingase lilingane nenani lokulinganisa). Ngasebenzisa i-gauge ye-pressure eyayingafaneleki kahle, kodwa ngesikhathi esifanayo ukuphakama kwakungu-0,5 kg / cm3, ubuningi ngesikhathi sokwanda kwejubane kusuka ku-XX kuya ku-5000 (i-gauge yokucindezela yagxuma futhi yawela ku- "0"). Ngakho, lokhu akubalwa.
Futhi emqondweni wami Lezi zindlela ezimbili zingahlanganiswa kanje:
1) khulula i-lambda phambi kwe-catalyst;
2) esikhundleni sale lambda, sifaka isikulufi;
3) qinisa ucezu lwepayipi yebhuleki ekufakweni (kukhona ngamabholithi enyunyana);
4) faka i-hose ekupheleni kwe-tube, futhi uyiphushe ku-cabin;
5) kahle, bese-ke, njengasekuqaleni;
Ngakolunye uhlangothi, sixhuma ku-gauge yokucindezela, ububanzi bokulinganisa obufika ku-1 kg / cm3. Kuyadingeka ukuqinisekisa ukuthi i-hose ayihlangani nemininingwane yesistimu yokukhipha umoya.
Ukucindezela kunqunywa igeji yokucindezela ngesikhathi sokusheshisa, ngokukhuphuka kwejubane, wonke amanani aqoshiwe. Esimeni lapho amanani okucindezela emuva ngesikhathi sokusebenza nge-damper evulekile ngokugcwele kunoma yiluphi uhla lwejubane edlula u-0,35 kg / cm3, lokhu kusho ukuthi uhlelo lokukhipha umoya ludinga ukuthuthukiswa.
6) ngenxa yokungasebenzi (i-lambda engafakwanga, isheke lizoqala ukushisa), ngemuva kokuthi i-lambda ifakwe endaweni, isheke lizophuma;
7) Umkhawulo we-0,35 kg / cm3 usetshenziselwa izimoto ezilungisiwe, kodwa ezimotweni ezijwayelekile, ngombono wami, ukubekezelelana kunganwetshwa ku-0,5 kg / cm3.
Uma ukuxilonga kwe-catalyst kubonisa ukumelana okwenyukayo ekudluleni kwamagesi e-exhaust, khona-ke i-catalyst idinga ukushaywa; uma ukukhukhula kungenakwenzeka, khona-ke i-catalyst kuzodingeka ishintshwe. Futhi uma ukushintshwa kungenzeki ngokwezomnotho, khona-ke sisusa i-catalyst. Ungafunda kabanzi mayelana nokuxilonga i-backpressure catalyst kuvidiyo engezansi:
