Injini ye-Nissan VQ30DET

Ngo-1994, i-Nissan yakha umugqa wama-sedans ekilasi lebhizinisi. Akhiqizwa ngezinjini zochungechunge lwe-VQ enamandla angama-cylinder angu-2, 2.5 no-3 amalitha. Izinjini zazizinhle, kodwa zingaphelele. Ukukhathazeka kwamaJapane kwawathuthukisa kancane kancane. Isibonelo, ukunciphisa isisindo, i-cast-iron cylinder block yenziwe nge-aluminium, futhi ibhande lesikhathi esifushane lashintshwa ngeketanga, okwandisa kakhulu impilo yalo yesevisi.

Kamuva, umenzi wanquma ukushiya ama-hydraulic lifters. Lokhu kwakudingeka ukuze kwandiswe ukuthunyelwa kwezimoto kwamanye amazwe okusekelwe kule njini emazweni lapho kwakusetshenziswa khona kakhulu amafutha amaminerali asezingeni eliphansi futhi ashibhile. Ukusetshenziswa kwazo ezinjinini ezinezinxephezelo ze-hydraulic kuholele ekuhlulekeni kwakamuva.

Bese bethuthukisa isistimu yokukhipha kanye ne-exhaust, bafaka ama-camshafts angu-2 ohlangothini ngalunye lwe-motor. Konke lokhu kuholele ekwenyukeni kwamandla kanye ne-torque yesikhungo samandla, futhi ukwanda kokuhlanza amakamelo kwabeka amandla okuphoqa. Ngenxa yalokho, kwavela ukuguqulwa okusha - VQ30DET. Yasetshenziswa kakade ngo-1995 futhi yaze yasetshenziswa izimoto 2008 (Nissan Cima).

Izimpawu nokuqoshwa kwegama

Amagama ezinhlobonhlobo nezinhlobo zezinjini zakwaNissan zikwenza kucace izici zazo. I-VQ30DET imele:

1. V - ukuqokwa kwesakhiwo (kulokhu, sisho isakhiwo esimise okwe-V).
2. U-Q igama lochungechunge.
3. 30 - ivolumu yesilinda (30 cubic dm. noma 3 amalitha).
4. D - ukuqokwa kwezinjini ezinama-valve angu-4 isilinda.
5. E - umjovo kaphethiloli we-elekthronikhi wamaphuzu amaningi.

Lokhu kwenza kucace amapharamitha ayisisekelo enjini.

Ukusetshenziswa kukawoyela	Kufika ku-500 amagremu ngebanga lika-1000 km.
Isisetshenziswa senjini	Ngaphezulu kwamakhilomitha ayizinkulungwane ezingama-400 (ngokusebenza)

Izimoto ezinenjini ye-VQ30DET

Lokhu kuguqulwa kusetshenziswa nemishini elandelayo:

1. Nissan Cedric 9 futhi 10 izizukulwane - kusukela 1995 kuya ku-2004.
2. Nissan Cima 3-4 izizukulwane - kusukela ngo-1996 kuya ku-2010.
3. Nissan Gloria 10-11 izizukulwane - kusukela 1995 kuya ku-2004.
4. Nissan Leopard 4 izizukulwane - kusukela 1996 kuya ku-2000.

Eziningi zalezi zimoto okubalwa kuzo iNissan Cedric yango-1995, zisahamba ngendlela ngenxa yokwethembeka nempilo ende yenjini.

Ubuchwepheshe be-Neo

Ngo-1996, ukukhathazeka kwaMitsubishi kwaqala futhi kwaqala ukukhiqizwa kwezinjini ngohlelo lwe-GDI. Isici sezinjini ezinjalo ezivuthayo zangaphakathi umjovo oqondile kaphethiloli kumasilinda ngaphansi kwengcindezi ephezulu kanye nomoya omningi kule ngxube (isilinganiso 1:40). KwaNissan benze umzamo wokutholana nembangi yabo ngqo base beqala nokwakha ubuchwepheshe obufanayo bomjovo kaphethiloli. Uchungechunge lwezinjini ezinomjovo kaphethiloli oqondile emakamelweni lwathola isiqalo segama - Neo Di.

Isici esiyinhloko sesistimu yiphampu yamafutha omfutho ophezulu. Ngenxa yakhe, ngokungenzi lutho, ingcindezi ye-60 kPa idalwe, futhi ngenkathi ushayela, ingakhuphukela ku-90-120 kPa.

Izinjini zomndeni wakwa-DE sezenziwe lezi zesimanje kanti kusukela ngo-1999 bafaka amamodeli anobuchwepheshe be-NEO. Ayefakwe ama-camshaft ashintshiwe kanye nesikhathi se-valve. Lawa ma-motor asethuthuke kakhulu kwezobuchwepheshe futhi anobungani bemvelo, kodwa ngesikhathi esifanayo umsebenzi wabo wawuncike kakhulu ekulawuleni i-electronic. Amandla ezitshalo zikagesi akashintshile, kodwa umthelela wazo olimazayo emvelweni wehlile.

Ukungasebenzi kanye nezinkinga zenjini ye-VQ30DET

Kwashiwo ngenhla ukuthi lokhu kuguqulwa akunawo ama-hydraulic lifters, ngakho kanye njalo ngamakhilomitha ayizinkulungwane eziyi-100 kuyadingeka ukulungisa ama-valve - lokhu kuyisici sokuklama salesi sikhungo samandla.

Kunezikhalo ku-inthanethi kubanikazi bezimoto abanalezi zinjini ngokuvuza kukawoyela nge-dipstick. Uma uqala imoto futhi uhlola izinga likawoyela, yonke i-dipstick ingase ifakwe amafutha. Ngesivinini esikhulu (izinkulungwane ezingu-5-6 rpm), ukukhafula kusuka ku-probe kungenzeka.

Ngesikhathi esifanayo, i-motor igijima ngokujwayelekile futhi ayishisi ngokweqile, noma kunjalo, izinga lokugcoba liyancipha, esikhathini esizayo eligcwele indlala yamafutha. Kukholakala ukuthi imbangela kungase kube amagesi ku-crankcase, angena lapho ngamasilinda. Lokhu kusho ukuthi amasilinda asegugile, noma amasongo. Inkinga efanayo akwenzeki kaningi, kodwa kwenzeka injini VQ30 (kanye nokulungiswa kwayo) nge mileage esiqinile.

Obunye ubungozi balezi zinjini:

1. Ukwephulwa kwesigaba sokusabalalisa igesi.
2. Ukuqhunyiswa, okuvame ukuhambisana nokwanda kokusetshenziswa kukaphethiloli. Ukuxazulula le nkinga, ukuhlanza ama-valve kusuka ku-soot kuyadingeka.
3. Izinzwa ze-MAF ezingalungile (amamitha omoya amaningi), okwenza injini idle umoya omkhulu - lokhu kudala ingxube ethambile kakhulu.
4. Ukulahleka kwengcindezi ohlelweni lukaphethiloli. Noma yiziphi izakhi zayo zingase zingasebenzi - iphampu yomjovo, izihlungi, isilawuli sokucindezela.
5. Ama-injection angasebenzi kahle.
6. Ukwehluleka kwama-catalysts, okuhlanganisa ukulahlekelwa amandla.

Imvamisa, abanikazi bezimoto ezinalezi zinjini bathintana nesiteshi sesevisi ngesikhalazo mayelana nokukhanya kwe-Check Engine. Ukuhamba unomphela noma kwesikhashana akubandakanyiwe (lapho enye yamasilinda ingasebenzi kahle noma ingasebenzi nhlobo), okuhambisana nokulahlekelwa amandla.

Ngokuvamile lokhu kuhlotshaniswa nenkinga ohlelweni lokuthungela. Uma “ubuchopho” buhlola ukusebenza kwamakhoyili futhi buthola noma yikuphi ukungasebenzi kahle, khona-ke bazisa umshayeli ngalokhu kusetshenziswa ilambu le-Check Engine.

Kulokhu, iphutha P1320 liyafundwa. Ngeshwa, udinga ukunquma ngokwakho ukuthi iyiphi ikhoyili engasebenzi, okuwuphawu lwesici ohlelweni lokuxilonga injini.

Izinjini ezinobuchwepheshe be-Neo zisebenzisa ama-valve e-EGR, anciphisa inani lama-nitrogen oxide kumagesi akhipha umoya. Le divayisi ayinangqondo futhi idinga izinga eliphezulu likaphethiloli. Uma usebenzisa uphethiloli wekhwalithi ephansi (ezweni lakithi, izinga likaphethiloli liphansi uma liqhathaniswa nophethiloli eYurophu), i-valve ingase imbozwe nge-soot ne-wedge. Kulesi simo, akusebenzi, ngakho-ke ingxube ye-fuel-air ehlinzekwa kumasilinda inezilinganiso ezingalungile. Lokhu kuhlanganisa ukwehla kwamandla, ukwanda kwebanga legesi kanye nokuguga kwenjini ngokushesha. Ngesikhathi esifanayo, ukukhanya kwenjini ethi Hlola kudeshibhodi kuyakhanyisa. Qaphela ukuthi i-valve ye-EGR iyinkinga ezinjinini eziningi lapho isetshenziswa khona, futhi hhayi ikakhulukazi izinjini zochungechunge lwe-VQ30DE.

isiphetho

Le njini iqoqa ukubuyekezwa okuhle phakathi kwabanikazi bezimoto - ayinasizotha ekunakekeleni, okuthembekile, futhi okubaluleke kakhulu - okuhlala isikhathi eside. Ungaqinisekisa lokhu ngokwakho ngokubheka amasayithi okuthengiswa kwezimoto ezisetshenzisiwe. Kukhona emakethe onobuhle Nissan Cedric kanye Cima 1994-1995 nge odometer amakhilomitha angaphezu kuka-250-300 ayizinkulungwane. Kulokhu, ungenza ukwanda kwedatha kudivayisi, ngoba abathengisi bavame ukusonta imayela "elisemthethweni".
