Isenzakalo ngemva kokuba i-valve yesikhala somjovo kaphethiloli sishile siwukuthi lapho injini isebenza, alukho ushintsho esimweni sokusebenza kwenjini lapho iqiniswa noma ixegisa isikulufu esilawula ukucindezela kumjovo kaphethiloli. Ngaphezu kwalokho, ngenxa yezindawo ezihlukene lapho inaliti yomjovo ishiswa khona, izinto eziboniswa lapho injini isebenza nazo zihlukile.

Lapho ivalve yenaliti ishiswa ivuliwe futhi injini isebenza, kuzoba nomsindo oshayayo wensimbi oyisigqi esilinda. Ngesikhathi esifanayo, ipayipi ye-exhaust nayo izokwenza umsindo othi "pop, pop", futhi ukuphuma kuzoba grey-white. Izinga lokushisa lombhobho wamafutha we-high-pressure we-injector libuye liphakeme kunelamanye amasilinda. Ngalesi sikhathi, uma umsindo ongqongqozayo unyamalala ngesikhathi sokuhlolwa kokunqanyulwa kukawoyela, lapho ipayipi likawoyela elinomfutho ophezulu lixegiswa, uphethiloli uzofuthwa endaweni ekhululiwe.

Lapho i-valve yenaliti ishiswa esimweni esivaliwe, i-valve yenaliti ayisebenzi lapho injini isebenza, ngakho-ke izinga lokushisa lepayipi likawoyela elinomfutho ophezulu wale silinda liphansi kunamanye amasilinda. Uma isilinda sinqanyulwa ukuze sihlolwe uwoyela, alukho ushintsho ekusebenzeni kwenjini. Kusuka epayipini likawoyela elinomfutho ophezulu Bheka ingxenye exegisiwe, kujovwa uphethiloli kuphela, hhayi umoya.

(1)Indlela yokuhlanganisa engalungile

① Amafutha e-anti-rust awazange akhishwe ngenkathi kufakwa i-nozzle kawoyela entsha. Ukuze uvimbele ukugqwala ngesikhathi sokugcina nokuthuthwa, umlomo womjovo kaphethiloli ngokuvamile umbozwa ungqimba lwamafutha avimbela ukugqwala. Uma ushintsha umjovo kaphethiloli, uma lawa mafutha engahlanzwa, amafutha avimbela ukugqwala azonamathela ku-valve yenaliti emazingeni okushisa aphezulu, okubangela ukuba ishise i-valve yenaliti yokujova uphethiloli.

② Ukuvuza kukadizili kumjovo kaphethiloli. Lapho ubuso bokugcina bomjovo kaphethiloli bumanzi ngenxa yokuvuza kwedizili, kungase kubangele ukusha kwendawo, futhi ukushisa okuvuthayo kudluliselwa ngokuqondile kumjovo kaphethiloli, okubangela ukuba ivalve yenaliti ishise.

③ Uma ufaka umjovo kaphethiloli, intambo ye-asbestos nezinye izinto zokuvikela kusetshenziswa esikhundleni samagaskhi ethusi, okuthinta ukuchithwa kokushisa kwenozi yomjovo kaphethiloli. Ingxenye yomhlahlandlela yevalvu yenaliti yomjovo kaphethiloli izoshisa ngokweqile, ibangele ivalve yenaliti ukuthi ingaguquguquki noma ibambeke.

④ Uma ufaka i-fuel injector, i-torque eqinisayo yomkhono wesikulufu inkulu kakhulu, evimbela ukunyakaza kwe-valve yenaliti.

⑤Igebe elifanayo phakathi komjovo kaphethiloli kanye nembobo yesihlalo somjovo kaphethiloli lincane kakhulu. Ngale ndlela, uma izinga lokushisa lenjini liphezulu, igebe elincane lasekuqaleni lokuhlanganiswa kwevalvu yenaliti liyachithwa, okubangela ukuba ishise ivalve yenaliti yomjovo.

(2) Kukhona ukungcola emgqeni kawoyela kaphethiloli

Amafutha e-diesel aqukethe izinhlayiya eziningi zokungcola ezinkulu kakhulu, okwamanje okuyisizathu esiyinhloko sokushisa i-valve yenaliti yomjovo. Isihlungi sikaphethiloli esisetshenziswa injini ngokuvamile singakwazi ukuhlunga kuphela ukungcola okukhulu kuno-0.05 mm. Ngokusobala, ikhono lokuhlunga alinamandla kakhulu. Uma isici sokuhlunga uphethiloli siqhuma ngalesi sikhathi, amaphedi azwakalayo aphezulu naphansi wesici sokuhlunga alahlekile noma alimele, okwenza ingxenye kaphethiloli ingene ngqo empompini yokujova uphethiloli, futhi ukungcola okukuyo kungase kungene kumjovo kaphethiloli futhi yivale.

(3) Izinga lokushisa lenjini liphezulu kakhulu futhi i-valve yenaliti iyasha.

① Injini ivamise ukusebenza ngesivinini esiphansi isikhathi eside, okwenza umfutho womjovo kaphethiloli wehle, futhi uwoyela ugeleze uzungeze umjovo ukuze wenze amadiphozithi ekhabhoni, okubangela ukuthi izinga lokushisa likhuphuke futhi lishise ivalve yenaliti.

② Amafutha agijimela egumbini elivuthayo futhi abangele inani elikhulu lamadiphozithi ekhabhoni kumjovo kaphethiloli ngemva kokusha, okwenza kube nzima ukuthi ukushisa kuphele kumjovo kaphethiloli futhi kubangele ukuba ivalve yenaliti ishise.
