Sisebenza Kanjani Isilawuli Sokucindezelwa Kwamafutha (Ukuhlola Nokushintsha I-RTD)
Okuqukethwe
Kusistimu yokulawula yenjini yemoto, imodeli ethile yezibalo ibekwa phansi, lapho amanani okukhiphayo abalwa ngokususelwa esilinganisweni salokho okokufaka. Isibonelo, ubude bokuvulwa kwama-nozzles buxhomeke kumthamo womoya nezinye izinto eziningi eziguquguqukayo. Kodwa ngaphandle kwabo, kukhona njalo njalo, okungukuthi, izici zesistimu kaphethiloli, ezibhaliswe enkumbulweni futhi azikho ngaphansi kokulawula. Omunye wabo ukucindezela kukaphethiloli kumzila wesitimela, noma kunalokho, umehluko phakathi kokufakwayo nokuphuma kwama-injection.
Iyini i-fuel pressure regulator?
Isibaseli kuma-injection siphuma ethangini ngokulimpompa ngepompo yesibaseli kagesi etholakala lapho. Amandla ayo awandile, okungukuthi, aklanyelwe ukusetshenziswa kakhulu kumodi enzima kakhulu, kanye nemajini ebalulekile yokuwohloka kokusebenza ngokuhamba kwesikhathi phakathi nokusebenza kwesikhathi eside.
Kodwa ipompo ayikwazi ukupompa njalo ngawo wonke amandla okushintsha kwamandla ayo, ukucindezela kufanele kube nomkhawulo futhi kuzinzile. Kulokhu, kusetshenziswa izilawuli ze-fuel pressure (RDTs).
Angafakwa kokubili ngqo kumojula yepompo kanye nakumzila kaphethiloli ophakela imibhobho yomjovo. Kulokhu, kufanele ulahle okweqile ngomugqa wokudonsa (ubuyisele) emuva ethangini.
Idivayisi
Isilawuli singaba ngumshini noma ngogesi. Esimeni sesibili, lolu uhlelo lokulawula lwakudala olunenzwa yokucindezela kanye nempendulo. Kodwa elula yomshini ayithembekile kangako, kuyilapho ishibhile.
Isilawuli esifakwe ujantshi siqukethe:
- imigodi emibili, eyodwa iqukethe uphethiloli, enye iqukethe ukudangala komoya okuvela kubuningi bokudla;
- i-diaphragm enwebekayo ehlukanisa imigodi;
- i-valve yokulawula elayishwe entwasahlobo exhunywe ku-diaphragm;
- izindlu ezinezinto zokubuyisela kanye nepayipi le-vacuum elivela ku-multifold intake.
Kwesinye isikhathi i-RTD iqukethe isihlungi se-mesh esimahhadla sokudlula uphethiloli. Sonke isilawuli sigibele irempu futhi sixhumana nesikhala saso sangaphakathi.
Ukuthi isebenza kanjani
Ukuze kulungiswe ingcindezi phakathi kwama-injection kanye nezindawo zokuphuma, kuyadingeka ukwengeza inani layo kumpambuko i-vacuum eyinegethivu ku-manifold, lapho imibhobho yomjovo iphuma khona. Futhi njengoba ukujula kwe-vacuum kuyahlukahluka kuye ngomthwalo kanye nezinga lokuvulwa kwe-throttle, udinga ukuqapha umehluko ngokuqhubekayo, uzinzise umehluko.
Kungaleso sikhathi kuphela lapho ama-injection azosebenza namanani ajwayelekile okusebenza kwawo, futhi ukwakheka kwengxube ngeke kudinge ukulungiswa okujulile nokujwayelekile.
Njengoba i-vacuum yepayipi ye-vacuum ye-RTD ikhula, i-valve izovuleka kancane, ilahle izingxenye ezengeziwe zikaphethiloli emgqeni wokubuyisela, kuzinzisa ukuncika esimweni somkhathi ezindaweni eziningi. Lokhu ukulungisa okwengeziwe.
Umthethonqubo oyinhloko ungenxa yokucindezela kwe-valve entwasahlobo. Ngokusho kokuqina kwayo, isici esiyinhloko se-RTD sijwayelekile - ingcindezi ezinzile. Umsebenzi uqhubeka ngokuvumelana nesimiso esifanayo, uma ipompo icindezela ngokweqile, khona-ke ukumelana ne-hydraulic ye-valve kuncipha, uphethiloli owengeziwe udonswa emuva ku-tank.
Izimpawu nezimpawu ze-RTD engasebenzi kahle
Kuye ngesimo sokungasebenzi kahle, ingcindezi ingase ikhule noma yehle. Ngokuvumelana nalokho, ingxube engena kumasilinda inothiswa noma iqedwe.
Iyunithi yokulawula izama ukulungisa ukwakheka, kodwa amandla ayo anomkhawulo. Ukusha kuyaphazamiseka, injini iqala ukusebenza ngezikhathi ezithile, ukukhanya kuyanyamalala, ukudonsa kuyawohloka, futhi ukusetshenziswa kuyanda. Futhi kunoma yikuphi, ingxube iyancipha, noma inothisiwe. Ngesikhathi esifanayo, ivutha ngokulinganayo.
Ungahlola kanjani ukuthi idivayisi iyasebenza yini
Ukuhlola, ingcindezi kurempu iyalinganiswa. Ifakwe i-valve lapho kungaxhunywa khona igeji yokucindezela yokuhlola. Idivayisi izobonisa ukuthi inani lingaphakathi kokujwayelekile noma cha. Futhi iphutha elithile lomlawuli lizoboniswa uhlobo lokusabela kokufundwa ekuvuleni kwe-throttle nokucisha umugqa wokubuya, okwanele ukuphoqa noma ukuxhuma i-hose yayo eguquguqukayo.
Ukukhipha i-vacuum hose ekufakweni kwe-RTD kuzophinde kubonise impendulo eyanele yengcindezi. Uma injini isebenza ngesivinini esincane, okungukuthi, i-vacuum yayiphezulu, khona-ke ukunyamalala kwe-vacuum kufanele kubangele ukwanda kwengcindezi kumzila wesitimela. Uma kungenjalo, isilawuli asisebenzi kahle.
Indlela yokuhlanza i-RTD
Umlawuli awukwazi ukulungiswa, uma kwenzeka ukungasebenzi kahle kushintshwa okusha, intengo yengxenye iphansi. Kodwa ngezinye izikhathi kungenzeka ukubuyisela amandla okusebenza ngokuhlanza i-mesh yokuhlunga eyakhelwe ngaphakathi. Ukuze wenze lokhu, umlawuli uhlakazwa futhi ugezwe nge-carburetor cleaner, elandelwa ukuhlanza.
Umsebenzi ungaphinda ukuze uthole imiphumela engcono. Kungenzeka futhi ukusebenzisa ukugeza kwe-solvent ye-ultrasonic, okusetshenziselwa ukuhlanza ama-injection lapho izinkinga ezifanayo zivela khona ngenxa yamafutha angcolile.
Alikho iphuzu elithile kulezi zinqubo, ikakhulukazi uma ingxenye isivele isebenze kakhulu. Izindleko zesikhathi nemali ziqhathaniswa nentengo ye-RTD entsha, naphezu kokuthi i-valve endala isivele igugile, i-diaphragm isigugile, futhi ama-caustic cleaning compounds angabangela ukwehluleka kokugcina.
Iziyalezo esikhundleni uphethiloli umfutho regulator usebenzisa isibonelo Audi A6 C5
Ukufinyelela kumlawuli kule mishini kulula, ifakwe kumzila we-fuel we-injection.
- Susa ikhava yepulasitiki yokuhlobisa phezulu kwenjini ngokukhulula ama-twist latches ngokuphambene newashi.
- I-screwdriver isetshenziselwa ukucisha nokukhipha isiqeshana sentwasahlobo sokulungisa emzimbeni womlawuli.
- Nqamula i-vacuum hose endaweni yesilawuli.
- Ingcindezi eyinsalela kuloliwe ingadamba ngezindlela ezihlukahlukene ngokuvumela injini ukuba isebenze uma iphampu yamafutha icishiwe, ngokucindezela i-spool ye-valve ye-pressure gauge kusitimela, noma ngokumane unqamule uhhafu wendlu yesilawuli. Ezimweni ezimbili zokugcina, udinga ukusebenzisa i-rag ukuze uthole uphethiloli ophumayo.
- Lapho i-latch isusiwe, umlawuli uvele asuswe ecaleni, emva kwalokho angawashwa, ashintshwe entsha, futhi ahlanganiswe ngokulandelana okuphambene.
Ngaphambi kokufakwa, kunconywa ukugcoba izindandatho zenjoloba zokuvala ukuze ungalimazi lapho ucwiliswa esisekelweni.
