Ukushintsha injini yesitovu yakwaNissan Qashqai

I-crossover encane kodwa ethokomele evela kwa-Nissan ithole ukuthandwa okukhulu eRussia, futhi lokhu kufaneleka ngokugcwele. I-Compact ngokubukeka, imoto inamandla amakhulu, okukuvumela ukuthi ungene kahle ku-cabin. Inzuzo eyengeziwe ingabhekwa ukusetshenziswa okuphansi kukaphethiloli: kule Qashqai ingaqhathaniswa ne-hatchback.

Isizukulwane sokuqala iNissan Qashqai J10 selokhu yakhiqizwa kusukela ngo-2006. Ngo-2010, kwenziwa restyling, okwathi ngemva kwalokho ingaphakathi lashintsha kakhulu futhi kwanezelwa izinjini eziningana ezintsha kanye namazinga gearbox Ukunquma.

Ukusetshenziswa kukaphethiloli okuphansi kunenzuzo futhi kumnandi, uma ungacabangi umthelela wokonga okunjalo ekushiseni isikhala. KwiNissan Qashqai ka-2008, into epholile ithatha ukushisa enjini bese ifudumeza ngayo umoya othunyelwa ngaphakathi emotweni. Kodwa uma injini isebenza ngokuntula uphethiloli, izinga lokushisa layo lokusebenza liphansi, ngakho-ke ayikwazi ukufudumala imoto ngokugcwele.

Yile nkinga ababhekane nayo abanikazi besizukulwane sokuqala iNissan Qashqai. Ngaphezu kokuthi ukubuyekezwa kwamakhasimende kubonisa ukwehluleka njalo kwemoto yesitofu, ngisho nangaphandle kwamaphutha, ingaphakathi lalishisa kancane.

Ngemva kokulungiswa kabusha, isimo sesishintshile saba ngcono. Ukuthi imininingwane yesistimu yokushisa ayizange ibe ngcono futhi ihlale isikhathi eside, kodwa ingaphakathi leQashqai liye lafudumala futhi likhululekile.

Isizukulwane sesibili i-Nissan Qashqai J11, eyakhululwa ngo-2014 (i-restyling ka-2017), yaphuma nezinguquko ezinkulu futhi ayisazi izinkinga ezinjalo. Isistimu yokushisisa isiklanywe kabusha, manje abanikazi bale moto akumele baqandwe yiqhwa. Ukufudumala imoto entsha (hhayi endala kuno-2012) imizuzu engu-10-15, ungakha izimo ezikhululekile ku-cabin, ngisho noma kukhona ukuphazamiseka okuthile emgwaqweni.

Ukushintsha injini yesitofu

I-Achilles heel yesizukulwane sokuqala i-Nissan Qashqai iyona kanye injini yesitofu. Izinkinga ezinkulu eziphakama ngalokhu:

1. Amabhulashi kanye nama-foil asulwa ngokushesha, ukuvuthwa kuyasha. Ngesikhathi esifanayo, isitofu siyayeka "ukushaya". Uma lokhu kuyinkinga, ungazama ukulungisa injini.
2. Ama-transistors amabi enza ukuthi isivinini semoto singalawuleki. Kulokhu, ama-transistors kufanele ashintshwe.
3. Umsindo obhayizayo noma oklabalasayo ongajwayelekile ngesikhathi sokusebenza kwesitofu uxwayisa ngokushintshwa kwenjini okuseduze. I-bushing iguga ngokushesha, okubangela umsindo oshisayo. Abaningi bazama ukuyishintsha ukuze kube ne-bearing, kodwa lokhu akuwona umqondo omuhle kakhulu - kuzothatha isikhathi esiningi, futhi ekugcineni ngeke kube nokusebenza okuthulile.

Ukungena kwamanzi okuphansi noma ukulahlekelwa ngokushesha kwesipholile kungase kungahlotshaniswa nesitofu ngokwaso, kodwa nge-radiator noma amapayipi. Ngaphambi kokudiliza isithando somlilo, kuyadingeka ukuhlola ubuqotho balezi zakhi. I-motor kagesi ingase ingadingi ukulungiswa, kodwa i-heater core noma amapayipi aphukile angase adinge ukushintshwa.

Isihlungi se-cabin esivalekile singase sibe necala ngokushisisa kahle kwangaphakathi; Ngaphambi kokuthenga izingxenye ezintsha zesitofu, kunconywa ukuthi uqale esikhundleni sokuhlunga. Mhlawumbe lokhu kuzoyixazulula ngokuphelele inkinga.

Ukushintsha injini yesitofu se-Nissan Qashqai akuyona inqubo elula, ngakho-ke abanikazi abaningi be-Qashqai bakhetha ukuya esiteshini sesevisi, naphezu kokuthi zingakanani izindleko zekhwalithi. Intengo ejwayelekile yomsebenzi izoba ngama-ruble angama-2000, lapho izindleko zenjini zengezwa - ama-ruble angama-4000-6000. Uma udinga ukufaka esikhundleni se-transistor, ungathenga entsha ngama-ruble ayi-100-200.

Uma kukhona izingxenye ezintsha, esikhundleni semoto yesitofu ochwepheshe kuzothatha amahora angu-3-4 wokuzilungisa ngezandla ezinekhono ngawo wonke amathuluzi adingekayo, kabili kakhulu. Uma ungakaze wenze umsebenzi onjalo ngaphambili, kodwa ube nethuluzi, isitofu esiphukile kanye nesifiso sokusilungisa, khona-ke kuzodingeka uchithe izinsuku ezimbili kule nkinga, hhayi ngaphansi. Kodwa ngokuzayo nakanjani kuzoshesha futhi kube lula.

Injini yesitofu iyingxenye engcono ukuthenga entsha kunaleyo esetshenzisiwe, futhi akudingekile ukuyibheka isikhathi eside. Iqiniso wukuthi izinjini zeNissan Qashqai neX-Trail ziyafana ncamashi.

Izinombolo zoqobo zenjini ye-heater yakwaNissan Qashqai:

• 27225-ET00A;
• 272250ET10A;
• 27225-ET10B;
• 27225-ДЖД00А;
• 27225-ET00B.

Izinombolo zenjini zangempela ze-heater yakwaNissan X-Trail:

• 27225-EN000;
• 27225-EN00B.

I-motor ingathengwa ngokuphepha nganoma iyiphi yalezi zinombolo, ifanele ukushintshwa.

Ungashintsha kanjani injini yesitofu ngezandla zakho

Ngaphambi kokushintsha noma ukulungisa injini, qiniseka ukuthi i-fuse ayizange iqhume.

Uhlu lwamathuluzi adingekayo wokushintsha injini ye-heater ngezandla zakho:

• i-ratchet enesandiso;
• screwdriver Torx T20;
• amakhanda angu-10 no-13 noma okhiye besayizi efanayo (kodwa amakhanda angcono kakhulu);
• abadayisi;
• izikulufriji eziphansi nezikaPhillips;
• abadonsa isiqeshana.

Isinyathelo ngesinyathelo inqubo:

1. Imoto iphelelwa amandla (kuqale kukhishwe itheminali enegethivu, bese kuba ephozithivu).
2. Ikhebuli yokukhipha ihood inqanyuliwe.
3. Kususwe ngokungaguquki - ohlangothini lwesobunxele lwedeshibhodi nangaphansi kwephaneli ngaphansi kwesondo lokuqondisa, konke kuma-rivets, indawo engcono kakhulu yokunquma kusengaphambili.
4. Izinzwa zesimo sezulu nesixhumi kunqanyuliwe kubhulokhi yenkinobho yesokunxele.
5. Sithola igumbi eliphezulu le-flap yokungena futhi sisuse i-clamp evikela izintambo.
6. Umhlangano we-pedal uyasuswa (ngaphambi kwalokhu, isixhumi sokushintshwa komkhawulo we-brake ne-accelerator siyasuswa).
7. Ngemuva kwalokho, i-cabin filter yezindlu iyaphuka.
8. Isixhumi samandla sinqanyuliwe enjini, ezungeziswa ngokuphambene newashi bese ikhishwa.

Ngemuva kokuthi i-motor isusiwe, kufanele ihlanzwe kudoti nokungcola futhi ihlole ama-winging namabhulashi. Uma kungenakwenzeka ukubuyisela ukusebenza kwenjini ye-heater endala, entsha ifakwe endaweni efanayo ngokulandelana okuphambene.

Isiphephetha-moya siyashintshwa ngemva kokuba injini imisiwe, ikhishiwe futhi yahlanzwa.

Ukushintshwa kwabalandeli be-heater

Isivinini sabalandeli esingaguquki, imisindo ehlabayo eyinqaba, nokungagelezi komoya ngemva kokuvula i-heater kungase kubonise inkinga ngesiphephetha-moya. Lokhu akusho ngempela ukuthi isiphephetha-moya sesitofu sidinga ukushintshwa, ngaphandle kwalapho ubuqotho baso obungokomzimba bonakalisiwe.

I-heater motor yakwaNissan Qashqai ithengiswa iphelele nge-impeller kanye ne-casing. Ungakwazi esikhundleni somshini wesitofu nge-Nissan Qashqai, kodwa lokhu akunangqondo: uma i-impeller yonakalisiwe noma igobile kancane, isitofu sizokhipha umsindo omkhulu futhi sihluleke ngokushesha, futhi lokhu cishe akunakwenzeka ukulinganisa ngokwakho.

Iphutha lingase lihlobane ne-transistor kusilawuli sesivinini noma i-resistor overheating; uma isha, ithathelwa indawo entsha.

Izinombolo ze-transistor ezifanele:

• I-IRFP250N - ikhwalithi ephansi;
• I-IRFP064N - izinga eliphezulu;
• I-IRFP048 - ikhwalithi ephakathi;
• I-IRFP064NPFB - ikhwalithi ephezulu;
• I-IRFP054 - ikhwalithi ephakathi;
• I-IRFP044 - ikhwalithi ephakathi.

Ukulungiswa kwezimoto

Kuye ngomonakalo, injini iyakhandwa noma ishintshwe ngokuphelele. Kwenzeka ukuthi ukulungiswa kungenzeka, kodwa hhayi okunengqondo: nakuba injini esetshenzisiwe e-disassembly izobiza kancane kunentsha esitolo, ukuthenga izingxenye ngazinye kungabiza kakhulu, uma zingatholakala nhlobo. Ezimweni ezinjalo, injini yesitofu ishintshwe ngokuphelele.

Kunoma yikuphi, isimo se-heater motor sihlolwa ngemuva kokuthi sihlakazwe futhi sihlanzwe othulini oluqoqwa kokubili emzimbeni nangaphansi kwalo.

Ngaphambi kokuqhubeka nokulungisa, kubalulekile ukuhlola:

• isimo se-bushing (noma sokuzala);
• ukuba khona komonakalo ku-fan;
• isimo sezintambo;
• ukuhlola ukumelana ekujikeni (kokubili i-rotor kanye ne-stator);
• hlola isimo sokuhlangana kwebhulashi.

Ngesikhathi esifanayo, imigudu yomoya iyahlanzwa, ukusebenza kwama-dampers, ukushintshwa kanye nazo zonke izingxenye ziyahlolwa.

Imiyalo

Ukuze uhlole isimo se-motor kanye nezingxenye ezibalulekile, kuyadingeka ukususa i-impeller (ngenxa yalokhu uzodinga ukhiye futhi ususe ngokucophelela i-motor endlini. Kulesi simo, uthuli kufanele lususwe. Ukuhlola nokufaka esikhundleni samabhulashi ku-a. I-Nissan Qashqai izodinga ukususa ipuleti lokubamba ibhulashi.

1. Ifeni ephukile ayilungiswa, kodwa ithathelwa indawo entsha.
2. Amabhulashi agugile angashintshwa, nakuba lokhu kuwumsebenzi onzima futhi kungcono ukushiyelwa ochwepheshe.
3. Uma i-rotor (ihange) lapho amabhulashi ejikelezayo igugile, kuzodingeka ushintshe yonke injini, akusizi ukulungisa endala.
4. Iwindi elishisiwe libuye liphele ngokushintshwa okuphelele kwenjini yesitofu.
5. Uma kudingekile ukufaka esikhundleni sokuthwala, ama-antenna aguqulwa futhi ingxenye entsha ifakwe. Izinombolo zengxenye ezifanele: SNR608EE kanye ne-SNR608ZZ.

Ukuzilungisa ngokwakho injini yesitofu ku-Nissan Qashqai kungenzeka. Njengokushintsha injini ye-heater, lokhu kuwumsebenzi onzima futhi onzima. Kungase kungenzeki ukwenza konke okulungile okokuqala, kodwa amehlo ayesaba, kodwa izandla zenza, into esemqoka ukungazithobi.
