Injini ye-Nissan VQ25HR
I-Nissan VQ25HR iyinjini engu-2.5 litre, engencane kunazo zonke emndenini wakwa-HR futhi ingu-V-cylinder eyi-6-cylinder. Ivele ngo-2006, yathola i-crankshaft eyenziwe ngomgunyathi kanye nezinduku zokuxhuma, i-timing chain drive, futhi yenziwa ngaphandle kwezinxephezelo ze-hydraulic.
Ngakho-ke, kunesidingo sokulungisa ama-valve.
Lena injini entsha enezici zochungechunge:
- Uhlelo lwe-eVTC kumashafu amabili.
- Izinti zokuxhuma ezinwetshiwe kanye nebhulokhi yesilinda eside.
- I-Molybdenum coated pistons.
- Amapusher acutshungulwa ngokobuchwepheshe obukhethekile obungenayo i-hydrogen.

Izimoto ezinenjini ye-VQ25HR
Injini yaseJapan yafakwa kule mishini elandelayo:
- Nissan Fuga - kusukela ngo-2006 kuze kube namuhla.
- Nissan Skyline - kusukela ngo-2006 kuze kube namuhla.
- I-Infinity G25 - 2010-2012
- I-Infinity EX25 - 2010-2012 гг.
- I-Infinity M25 - 2012-2013
- I-Infinity Q70 - 2013-ekhona
- Mitsubishi Proudia – 2012-н.в.
I-motor yavela ngo-2006 futhi phakathi no-2018 ifakwe kumamodeli amasha okukhathazeka okuhamba phambili kweJapane, okuqinisekisa ukuthembeka kwayo, ukukhiqizwa kanye nekhwalithi.
Ukuxhaphaza
I-VQ25HR iyinjini enamandla ene-torque ephezulu ngesivinini esikhulu. Lokhu kusho ukuthi injini kufanele iguqulwe futhi "ingadonswa" ngesivinini esiphansi esifundeni se-2000 rpm, njengoba kwenza abashayeli abaningi. Uma usebenza njalo injini yomlilo yangaphakathi ngesivinini esiphansi, khona-ke ukupheka kungenzeka, okuzoholela ekuveleni kwezindandatho ze-oil scraper. Lokhu kuzobonakala ekusetshenzisweni kwamafutha aphezulu, ngakho-ke kuhle ukulawula ngokuhlelekile izinga layo ngemva kwamakhilomitha ayizinkulungwane eziyi-100.
Ngokusho kwabanikazi, i-chain chain ayikhali ngemva kwamakhilomitha ayizinkulungwane eziyi-100 (umkhiqizi uncoma ukuyishintsha ngemva kwe-200-250 km eyizinkulungwane.), Futhi izindleko zokuyishintsha ziphansi, okuyinto ehlanganisa. Iqoqo lamaketanga okuqala kanye nama-tensioners lizobiza ama-ruble ayizinkulungwane ezingu-8-10.
Ukusetshenziswa kukaphethiloli kuphezulu. Ebusika, ngokushayela ngobudlova, injini “idla” amalitha angu-16 kaphethiloli, noma ngisho nangaphezulu.
Kuyafaneleka ukucabangela ukuthi injini ithanda isivinini, futhi idinga ukungasonti ngokuqinile, ngakho-ke ukusetshenziswa kuphezulu. Lapho ushayela emgwaqeni omkhulu, ukusetshenziswa kukaphethiloli kungamalitha ayi-10 ngekhulu, okuwumphumela owamukelekayo weyunithi enamandla engu-2.5-litre.
Izinkinga
Naphezu kokuthi injini ye-VQ25HR inokwethenjelwa futhi inomthombo ophezulu, ithole izinkinga ezithile:
- Ukushisa ngokweqile. Ukusebenza isikhathi eside ngesivinini esiphezulu kakhulu kungaholela ekushiseni ngokweqile. Lokhu kungenzeka kakhulu ukubhoboza ama-cylinder head gaskets. Ngenxa yalokho, i-antifreeze izongena emakamelweni omlilo.
- Isivinini sokubhukuda nokusebenza okungazinzile kwenjini evuthayo yangaphakathi, okubangelwa ukukhishwa kwama-gaskets amashaneli kawoyela. Iphutha elihambisanayo lizovela kudeshibhodi.
- Ukwenyuka kokusetshenziswa kukawoyela. Isizathu sokushiswa kukawoyela ngemuva kwamashumi ezinkulungwane zamakhilomitha kuzoba ukuphekwa kwenjini. Ngenxa yalokho, izindandatho ze-oil scraper ngeke zisasebenza ngokuphumelelayo ngenxa yenani elikhulu le-carbon deposits.
- Ukuquleka ezindongeni zesilinda. Ezinjinini ezisetshenzisiwe, ama-scuffs avela ezindongeni zesilinda. Isizathu sokubukeka kwabo ukungena emakamelweni avuthayo ezingxenye ze-catalytic converter, ezibonakala lapho lapho ama-valve evaliwe. Yingakho abanikazi bevame ukususa ingxenye ye-catalyst eseduze nendawo yokuphuma.
Ukufingqa, i-VQ25HR iyinjini yaseJapan ethembekile nesezingeni eliphezulu engenakho ukubala okungalungile nokushiyeka okuholela ezinkingeni zomhlaba. Ngakho-ke, ngokulungiswa okufika ngesikhathi futhi okufanele, injini "izogijima" amakhilomitha ayizinkulungwane ezingu-200 ngaphandle kokuphuka.
Imakethe yesibili
Izinjini zenkontileka i-VQ25HR zithengiswa kumasayithi afanelekile. Intengo yabo incike ezingeni lokugqoka, i-mileage, isimo. Amayunithi angasebenzi "yezingxenye ezisele" athengiswa ngama-ruble ayizinkulungwane ezingama-20-25, izinjini ezisebenzayo zingathengwa ngama-ruble ayizinkulungwane ezingama-45-100. Yiqiniso, izindleko zezinjini ezintsha ezikhishwe kamuva ziphakeme kakhulu.
