Izinjini Nissan vg30e, vg30de, vg30det, vg30et
Okuqukethwe
Uhlu lwenjini yakwaNissan vg luhlanganisa amayunithi amaningana ahlukene. Izinjini ziyizinjini ezivuthayo zangaphakathi ezisebenza kahle kakhulu nanamuhla.
Kufakwe kumamodeli ezimoto ahlukahlukene. Ngokuvamile, ukubuyekezwa mayelana motors zinhle, kodwa kukhona umehluko omkhulu phakathi kwabo.
Incazelo yenjini
Lolu chungechunge lwezinjini lwethulwa emuva ngo-1983. Kuvezwa izinketho eziningana ezahlukene. Kukhona ukuguqulwa okungu-2 no-3 wamalitha. Okubalulekile emlandweni ukuthi imodeli iyinjini yokuqala evuthayo yangaphakathi emise okwe-V enamasilinda ayisithupha esuka kwaNissan. Ngemva kwesikhashana, kwadalwa izinguquko ngevolumu 3.3 amalitha.
Izinhlobonhlobo zezinhlelo zokujova zaqala ukusetshenziswa. Izici zezinto ezisetshenziswa ekwakheni:
- i-iron block;
- ikhanda le-aluminium.
Ekuqaleni, izinjini zohlelo lwe-SOCH zakhiqizwa. Lokhu kwakusho ukuba khona kwe-camshaft eyodwa kuphela. Kwakukhona ama-valve angu-12, ama-2 kusilinda ngasinye. Kamuva, kwenziwa izinguquko eziningana ezihlukahlukene. Umphumela wesimanje kwaba ukusetshenziswa komqondo we-DOHC (ama-camshaft ama-2 namavalvu angama-24 - 4 kusilinda ngasinye).
Технические характеристики
Imvelaphi evamile yalezi zithuthuthu izenza zifane. Kodwa kukhona umehluko omkhulu ezicini zobuchwepheshe zenjini yomlilo yangaphakathi:
| Igama lesici | vg30 e | vg30de | vg30det | vg30et turbo |
|---|---|---|---|---|

Izinjini zalolu hlobo azikaze zifakwe ezimotweni zesimanje isikhathi eside. Noma kunjalo, izimoto ezithengwa emakethe yesibili ezifakwe ama-motor anjalo ziyadingeka. Isizathu esiyinhloko ukulula kokugcinwa, ukuzithoba kuhlobo lukaphethiloli osetshenzisiwe. Ngisho uma uyiqhathanisa nezimoto zanamuhla, i-vg series yakwaNissan idla uphethiloli omncane. Ngokwehlukana, kufanele kuqashelwe ukuthi kungenzeka ukuzihlola injini.
Ngisho nangemva kweminyaka engu-30 usendleleni, ungathola izimoto ezihlanganiswe namamodeli e-ICE alolu chungechunge. Isizathu esiyinhloko salokhu akukhona nje ukuzithoba kanye nokungabizi kakhulu kokulungisa. Kodwa futhi umthombo obalulekile wale motor. Ngokusho kwabanikazi, ngaphambi kokulungiswa kokuqala, i-mileage icishe ibe yizinkulungwane ezingama-300 km. Kodwa le nkomba ayiwona umkhawulo, konke kuncike kwikhwalithi yamafutha asetshenzisiwe, kanye nokushintshwa kwayo ngesikhathi.
Ngokungafani nezinjini eziningi ezifanayo ezivela kwaNissan, ngeke kube nzima ukuthola inombolo yenjini. Kukhona insimbi ekhethekile enolwazi ngenombolo yenjini, kanye nenye eduze kwejeneretha, ebhulokhini lensimbi. Kubukeka kanjena:
Ukuthembeka kwezimoto
Uchungechunge lwezinjini alufani nje kuphela ekulondolozeni kwayo, kodwa futhi nokuthembeka. Ngokwesibonelo, ungathola "Nissan Terrano" emakethe yesibili ifakwe VG uchungechunge injini mileage kuka 400 ayizinkulungwane km. Ngaphandle komehluko phakathi kwe-vg30de, vg30dett namanye amamodeli avela ochungechungeni, wonke anempilo ende yesevisi. Ukungasebenzi kahle okulandelayo kungenzeka ngesikhathi sokusebenza:
- phusha lapho usuka egiyeni lokuqala uye elesibili - ngokuvamile inkinga isesiteji esisemuva esiphakathi kwebhokisi legiya nesigaxa segiya;
- ukwanda kokusetshenziswa kukaphethiloli emjikelezweni ohlangene - ukushaywa kwenjini kuyadingeka, ikakhulukazi indlela yokungenisa.
Ukulondolozeka
Inzuzo ebalulekile ye-motor, ngisho nangaphezu kwama-analogues anamuhla, ukugcinwa.
Injini kulula ukuyiqaqa. Ngokwehlukana, kufanele kuqashelwe ukuthi kungenzeka ukuzihlola lokhu motor. Iyunithi yokulawula ayidingi ukuxhumeka kwedivayisi ekhethekile yokuxilonga. Kuzokwanela ukusebenzisa ukukhishwa kwephutha kwe-Nissan.
Iyunithi ye-elekthronikhi yibhokisi lensimbi lapho kukhona umgodi - liqukethe ama-LED amabili. I-diode ebomvu ibonisa amashumi, i-diode eluhlaza ibonisa amayunithi. Indawo yeyunithi ingase yehluke kuye ngemodeli yemoto (ensika engakwesokudla, ngaphansi komgibeli noma isihlalo somshayeli). Kubalulekile ukuqaphela ukuthi injini yesistimu ye-DOHC ifakwe ibhande lesikhathi, elidinga ngezikhathi ezithile ukulungiswa nokushintshwa kwezingxenye ngazinye. Ukufakwa kwebhande kufanele kwenziwe ngokuqinile ngokuvumelana namamaki.
Uma ibhande lingashintshwa ngesikhathi futhi lidabukile, ama-valve azogotshwa ngokushaywa kwamapiston. Ngenxa yalokho, kuzodingeka ukulungiswa kabusha kwenjini. Lapho ushintsha ibhande lesikhathi, uzodinga ukushintsha:
- amarola okuqondisa;
- izindlala zamafutha "ebunzini";
- iqondisa ku-pulley yesikhathi esikhethekile.
Kubalulekile ukuhlola ukucindezela. Kufanele ibe phakathi kwe-10 kuya ku-11. Uma iwa ku-6, kuyadingeka ukugcwalisa amasilinda ngamafutha. Uma emva kwalokho ukucindezelwa kwanda, kuyadingeka ukufaka esikhundleni sezimpawu ze-valve stem. Ukuze usethe ukuthungela, kufanele uxhume i-stroboscope. Udinga ukunakwa okwengeziwe:
- i-thermostat - uma ihluleka, i-fan yokupholisa izoyeka ukuvula;
- isignali ku-tachometer - yilokho okubangela ukungasebenzi kokugcina;
- amabhulashi okuqala - ukuhlolwa okubonakalayo kuyadingeka.
Kubalulekile ukuhlola ngezikhathi ezithile inzwa yokushaya. Ezinye izingxenye kufanele nazo zibe ngohlelo lokusebenza. Uma kungenjalo, kukhona ukusetshenziswa kukaphethiloli okwenyukile. Kungase kube nezinye izinkinga zenjini.
Hlobo luni lwamafutha lokuthela
Ukukhethwa kwamafutha kungenye yamaphuzu abaluleke kakhulu. Esinye sezixazululo ezinhle kakhulu yi-Enemos Gran Touring SM. Ngokuvamile i-5W-40, i-SAE isetshenziswa. Kodwa ingabuye igcwaliswe ngamafutha avela kwabanye abakhiqizi, ukuhambisana okuhlukile.
Abaningi basebenzisa amafutha okuqala. Ngokwesibonelo, Nissan 5W-40. Ngokusho kwabanye abanikazi bezimoto, ukusetshenziswa kwe-ZIK kuholela ekwandeni kokusetshenziswa kwamafutha enjini. Ngakho-ke, ukusetshenziswa kwayo akuthandeki. Lapho ukhetha, kubalulekile ukulandela izincomo zomkhiqizi.
Uhlu lwezimoto okwafakwa kuzo izinjini
Uhlu lwezimoto ezihlinzekwa ngezinjini ezihambisanayo luningi kakhulu. Kuhlanganisa:
| vg30 e | vg30de | vg30det | vg30et turbo |
|---|---|---|---|
| yokubeka indlwana eyakhelwe amasondo | Cedric | Cedric | Cedric |
| Cedric | Cedric Cima | Gloria | UFairlady Z |
| Gloria | UFairlady Z | I-Nissan | Gloria |
| Ekhaya | Gloria | Phezulu | |
| UMaxima | Gloria Cima | I-Leopard | |
| I-Leopard |
Ngeke kube nzima ukuthola ku-inthanethi ukubuyekezwa kwenjini, okuthwetshulwe kukhamera yevidiyo (isibonelo, i-sony nex). Lokhu kufanele kwenziwe ngaphambi kokuthenga imoto efakwe injini ye-vg30e noma efanayo. Kubalulekile ukuqonda imininingwane yokusebenza kwemishini enjalo. Injini iyalungiseka, izingxenye ezisele ziyatholakala ukuze zidayiswe. Kodwa ngesikhathi esifanayo, izindleko zezingxenye ziphakeme kakhulu.
