Iyini uphawu lwe-valve yemoto
I-valve oil seal uhlobo lwe-oil seal oluvame ukwenziwa ngokuhlanganisa uhlaka lwangaphandle kanye ne-fluororubber ndawonye. I-spring eziqinisayo noma ucingo lwensimbi lufakwa ekuvulekeni kwe-radial kwe-oil seal ukuze kuvalwe induku yokuqondisa i-valve yenjini. Iyingxenye ebalulekile yokuhlanganiswa kwe-valve yenjini. I-valve oil seals ingavimbela uwoyela wenjini ukuthi ungene emapayipini okungenisa kanye nawokukhipha umoya futhi igweme ukulahleka kukawoyela. Ingavimbela futhi ukuvuza kwengxube kaphethiloli, umoya kanye negesi yokukhipha umoya.

Kuyingxenye ebalulekile yokuhlanganiswa kwamavalvu enjini. Izivalo zikawoyela wamavalvu zingavimbela uwoyela wenjini ukuthi ungene emapayipini okungenisa kanye nawokukhipha umoya futhi zigweme ukulahleka kukawoyela. Kungavimbela futhi ukuvuza kwengxube kaphethiloli, umoya kanye negesi yokukhipha umoya, futhi kuvimbele uwoyela wenjini ukuthi ungene ekamelweni lokushisa.
Ngenxa yokuthi ihlangana nophethiloli namafutha enjini emazingeni okushisa aphezulu, izinto ezimelana nokushisa okuhle kakhulu kanye nokumelana namafutha, njenge-fluororubber, zidinga ukusetshenziswa.
I-oil seal iyisici sokuvala esisetshenziswa emishinini ukuvala uwoyela. Ingahlukanisa izingxenye zokudlulisela ezidinga ukugcotshwa engxenyeni ephumayo ukuvimbela ukuvuza kwamafutha okugcoba. I-valve oil seals iwuhlobo lwe-oil seal.
Uma ukhetha izinto zokuvala uwoyela we-valve, kufanele kuqashelwe ngokukhethekile izinga lokushisa lokusebenza kwezivalo zikawoyela we-nitrile raba ezingama-degree Celsius angu-40 kuya ku-120, irabha ye-acrylic engama-degree Celsius angu-30 kuya ku-180, kanye nerabha ye-fluorine engama-degree Celsius angu-25 kuya ku-300. Izinga lokushisa lomlomo wesivalo sikawoyela ngokuvamile liphakeme ngama-degree Celsius angu-20 kuya ku-50 kunelendawo yokusebenza. Ngakho-ke, kubalulekile ukukhetha izinto zokuvala uwoyela ezifanele ngokusekelwe esimweni sangempela ukuqinisekisa ukuthi zingasebenza ngokujwayelekile futhi zidlale indima enhle yokuvala endaweni efanele.
Izimpawu eziyinhloko zokwehluleka kokuvalwa kwe-valve uwoyela ukuvuza kwe-oyela egumbini lokushisa, okubangela izinkinga ezifana nentuthu eluhlaza okwesibhakabhaka evela ekukhishweni komoya kanye nokusetshenziswa kwe-oyela okungajwayelekile. Kudingeka ukulungiswa ngesikhathi. Ukuminyana kwendandatho ye-piston, ukuguga kwe-valve uwoyela, kanye nomonakalo kuma-valve okukhipha kuyizimbangela ezivamile. I-Youdaoplaceholder0.
Izimpawu eziyinhloko
Intuthu eluhlaza okwesibhakabhaka evela emsipheni: Lokhu kubonakala kakhulu ngesikhathi sokuqala okubandayo, njengoba uwoyela wenjini ungena egumbini lokusha bese usha, okwenza intuthu eluhlaza okwesibhakabhaka.
I-Youdaoplaceholder0 Ukusetshenziswa kukawoyela okungajwayelekile : Izinga likawoyela lehla kakhulu ngemva kokushayela izinkulungwane zamakhilomitha.
Ukwehla kwamandla e-Youdaoplaceholder0: Amadiphozithi ekhabhoni avala izinhlangothi zombili zamavalvu, okuholela ekunciphiseni ukusebenza kahle kokungenisa.
I-Youdaoplaceholder0 Ama-spark plug carbon deposits : Angcoliswe uwoyela wenjini, aveza ukubukeka okumnyama nokunamafutha.
Ukuhlaziywa kwembangela
Ukuguga kwesivalo sikawoyela se-Youdaoplaceholder0: Izingxenye zerabha ziyaqina ngokuhamba kwesikhathi, futhi ukusebenza kwesivalo kuyehla (zivame ukulimala ngemva kwamakhilomitha ayi-150,000).
Ukwehluleka kwevalvu yokukhipha umoya ye-Youdaoplaceholder0: ukungalingani kwengcindezi ohlelweni lokungenisa umoya lwe-crankcase, umhwamuko kawoyela udonswa egumbini lokushisa.
Ukuminyana kwendandatho ye-piston ye-Youdaoplaceholder0: Amadiphozithi e-carbon avala umgodi wokubuyisa uwoyela, alahlekelwe umsebenzi wokukhuhla uwoyela (okuvame kakhulu ezimotweni ezimakhilomitha aphakathi naphezulu).
Isixazululo
I-Youdaoplaceholder0 ishintsha izingxenye zefektri zokuqala
Nika kuqala ukufaka esikhundleni i-valve cover assembly (kufaka phakathi umklamo ohlanganisiwe we-oil seal kanye ne-exhaust valve).
Ukulungiswa kwe-Youdaoplaceholder0 ngaphandle kokuyiqaqa
Sebenzisa izihlanzi zohlobo lwe-PNF ukuze uncibilikise amadiphozithi ekhabhoni futhi ubuyisele ukuqina kwamasongo e-piston (afanele izimoto ezingaphakathi kwamakhilomitha ayi-100,000).
Ukunakekelwa kwansuku zonke kwe-Youdaoplaceholder0
Hlanza njalo imigqa kaphethiloli ngezithasiselo zikaphethiloli (kanye njalo ngamakhilomitha ayi-10,000 kuya kwangu-20,000).
Khetha uwoyela wenjini owenziwe ngokuphelele ohambisana nezindinganiso ze-ACEA C3.
Isexwayiso Sengozi
Gwema ukushayela ibanga elide elifushane (uhambo oluya endaweni eyodwa olungaphansi kwamakhilomitha ama-5 lungenza kube nzima kakhulu ukudonsa i-carbon deposits) futhi kwandise izinga likawoyela wenjini ngaphandle kwemvume.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
Inkampani Zhuo Meng Shanghai Auto Co., Ltd. uzibophezele ekuthengiseni i-MG&I-MAXUSizingxenye zezimoto zamukelekile ukuthenga.
