Injini ye-Opel Z19DT
Okuqukethwe
Izinjini zikadizili ezikhiqizwe ngabakwaGeneral Motors zaziwa kabanzi njengamayunithi kagesi asezingeni eliphezulu, athembekile futhi ahlala isikhathi eside akwazi ukuhamba amakhulu ezinkulungwane zamakhilomitha ngaphandle kokulungiswa okwengeziwe nokulungiswa okumba eqolo. Imodeli ye-Opel Z19DT ayihlukile, okuyinjini yedizili ene-turbocharged efakwe ezimotweni zochungechunge lwe-C no-H, isizukulwane sesithathu. Ngokuklama kwayo, le njini ibolekwe kancane kwa-FIAT, futhi umhlangano wenziwa ngokuqondile eJalimane, endaweni edume kabi, isitshalo sesimanje esisedolobheni laseKaiserslautern.
Ngesikhathi sokukhiqizwa kwayo kusukela ngo-2004 kuya ku-2008, le njini engu-four-cylinder diesel yakwazi ukuzuza izinhliziyo zabashayeli abaningi futhi yabe isikhishwa emakethe ngozakwabo wakwa-Opel ngokumakwa kwe-Z19DTH. Lokhu kungenye yezonga kakhulu futhi ngesikhathi esifanayo amayunithi amandla athembekile esigabeni sawo. Ngokuqondene nama-analogue anamandla amancane, injini ye-Z17DT nokuqhubeka kwayo i-Z17DTH kungashiwo ngokuphepha kulo mndeni.

Izici zokuklama i-Z19DT
Idizayini elula futhi enokwethenjelwa ivumela lawa mayunithi amandla ukuthi anqobe kalula ngaphezu kwezinkulungwane ezingama-400 ngaphandle kokulungiswa okukhulu.
Amayunithi kagesi aklanyelwe ngqo ukusebenza isikhathi eside futhi ahlukaniswa ngekhwalithi yensimbi nokuhlanganisa.
I-Common Rail fuel equipment system eyaziwa kakhulu nayo isinezinguquko. Indawo yemishini evamile yakwaBosch, imishini yeDenso isihlinzekwa ngalezi zinjini. Inokwethenjelwa okuphezulu, nakuba kunzima kakhulu ukulungisa, ngenxa yokuntuleka kwenani elikhulu lezikhungo zesevisi.
Amaphutha ethandwa kakhulu Z19DT
Kumele kuqashelwe ngaso leso sikhathi ukuthi izinkinga eziningi ezingase zivele ngesikhathi sokusebenza kwalezi zinjini ezivuthayo zangaphakathi zivela ngenxa yokugqoka kwemvelo nokukhala noma ukusebenza okungalungile. Le motor ayikho ngaphansi kokuqhekeka okubukhali, njengoba bethi "Out of the blue".
Izinkinga ezivame kakhulu ochwepheshe babiza:
- ukuvala noma ukushiswa kwesihlungi sezinhlayiyana. Ukulungisa kuvame ukuhlanganisa ukusika izinhlelo ezingenhla kanye nezibenyezayo;
- ukugqokwa komjovo kaphethiloli. Inkinga ixazululwa ngokufaka esikhundleni salokhu okungenhla futhi kuvela ekusetshenzisweni kwamafutha asezingeni eliphansi namafutha, kanye nokushintshwa okungavamile koketshezi olusebenzayo;
- ukwehluleka kwe-valve ye-EGR. Ukungena okuncane komswakamo kuholela ekumuncu nasekuminyeneni kwawo. Ukuxilongwa kanye nesinqumo sokulungisa noma ukushintshwa kwalesi sisetshenziswa senziwa ngokushesha ngemva kokuxilongwa kusevisi yemoto ekhethekile;
- qeda izinkinga eziningi. Ngenxa yokushisa ngokweqile, okungenhla kungase konakale. Ngaphezu kwalokho, ngokuvamile kukhona ukuwohloka kwe-vortex dampers;
- ukuhlukaniswa kwemojula yokushisa. Kungabangelwa ukusetshenziswa kwamafutha enjini amabi namapulagi ezinhlansi ezisezingeni eliphansi. Ngakho-ke, lapho ushintsha, kuyadingeka ukunaka kuphela imikhiqizo enconywe umenzi;
- ukuvuza kwamafutha emajoyintini nangaphansi kwama-gaskets nama-seal. Inkinga yenzeka ngemuva kwamandla okucindezela aphezulu kakhulu, ngemuva kokulungiswa. Inkinga ilungiswa ngokufaka esikhundleni salokhu okungenhla.
Ngokuvamile, le yunithi isibe isisekelo sokuthuthukiswa okuhlukahlukene nokuthuthukiswa. Ifakwe ezimotweni eziningi futhi abashayeli abaningi abanandaba ukuthenga inkontileka Z19DT yemoto yabo.
Yiziphi izimoto ezifakiwe
Lezi zinjini zisetshenziswa kakhulu ezimotweni ze-Opel zesizukulwane sesi-3, okuhlanganisa nezinguqulo ezenziwe kabusha. Ikakhulukazi, lezi motors ziye zathandwa ikakhulukazi kumamodeli we-Astra, Vectra kanye ne-Zafira. Banikeza izinga elanele lamandla, impendulo ye-throttle kanye nokusabela, kuyilapho behlala benomnotho kakhulu futhi benobungani bemvelo.
Njengokuthuthukiswa okunikeza ukwanda kwamandla, iningi labashayeli bezimoto linqunyelwe ukulungiswa kwe-chip, okungangeza i-20-30 hp. Okunye ukuthuthukiswa akunanzuzo ngokombono wezomnotho, futhi kulokhu kungcono ukuthenga i-analogue enamandla kakhulu kulo mndeni wamayunithi wamandla. Lapho uthenga ingxenye yenkontileka, ungakhohlwa ukuhlola inombolo yenjini naleyo ekhonjiswe kumadokhumenti.
Itholakala lapho kuhlangana khona ibhulokhi kanye nendawo yokuhlola, kufanele ibe bushelelezi futhi icace, ngaphandle kokugxuma izinhlamvu nokugcoba. Uma kungenjalo, isisebenzi esihlolayo se-state traffic inspectorate sizoba nombuzo ozwakalayo, nokuthi ngabe inombolo yale yunithi iphazamisekile futhi, ngenxa yalokho, injini izohlolwa okuhlukahlukene.
