Cav Nissan vg30e, vg30de, vg30det, vg30et
Txheem
Nissan's vg engine lineup suav nrog ntau chav sib txawv. Cov cav tov yog cov cav combustion sab hauv uas muaj kev ua tau zoo txawm tias niaj hnub no.
Nruab rau ntau lub tsheb qauv. Feem ntau, kev tshuaj xyuas txog cov motors yog qhov zoo, tab sis muaj qhov sib txawv loj ntawm lawv.
Cav piav qhia
Qhov no series ntawm motors tau nthuav tawm rov qab rau xyoo 1983. Muaj ntau qhov kev xaiv sib txawv tau nthuav tawm. Muaj 2 thiab 3 litre kev hloov kho. Lub keeb kwm feature yog hais tias tus qauv yog thawj puas V-zoo li tus rau-lub tog raj kheej combustion engine los ntawm Nissan. Ib me ntsis tom qab, kev hloov kho nrog lub ntim ntawm 3.3 litres tau tsim.
Ntau hom kev txhaj tshuaj tau pib siv. Cov yam ntxwv ntawm cov khoom siv hauv kev tsim kho:
- hlau thaiv;
- aluminium taub hau.
Thaum pib, cov cav ntawm SOCH system tau tsim. Qhov no txhais tau tias tsuas muaj ib lub camshaft xwb. Muaj 12 li qub, 2 rau txhua lub tog raj kheej. Tom qab ntawd, ntau qhov kev hloov kho sib txawv tau tsim. Qhov txiaj ntsig ntawm kev hloov kho tshiab yog kev siv lub tswv yim DOHC (2 camshafts thiab 24 li qub - 4 rau txhua lub tog raj kheej).
Технические характеристики
Lub hauv paus chiv keeb ntawm cov motors no ua rau lawv zoo sib xws. Tab sis muaj qhov sib txawv tseem ceeb hauv cov yam ntxwv ntawm lub tshuab hluav taws xob sab hauv:
| Lub npe yam ntxwv | v 30 e | vg30 ua | vg30 ua | vg 30 turbo |
|---|---|---|---|---|

Lub cav ntawm hom no tsis tau muab tso rau hauv cov tsheb niaj hnub tau ntev. Txawm li cas los xij, cov tsheb yuav ntawm cov khw muag khoom thib ob uas muaj cov motors zoo li no yog xav tau. Qhov laj thawj tseem ceeb yog qhov yooj yim ntawm kev saib xyuas, unpretentiousness rau hom roj siv. Txawm hais tias piv rau cov tsheb niaj hnub no, Nissan's vg series siv roj tsawg. Cais, nws yuav tsum tau muab sau tseg tias muaj peev xwm ntawm tus kheej-kev kuaj mob ntawm lub cev muaj zog.
Txawm tias tom qab 30 xyoo ntawm txoj kev, koj tuaj yeem pom cov tsheb sib sau ua ke nrog ICE qauv ntawm cov koob no. Lub ntsiab yog vim li cas rau qhov no tsis yog tsuas yog lub unpretentiousness thiab txheeb ze cheapness ntawm kho. Tab sis kuj yog ib qho chaw tseem ceeb ntawm lub cev muaj zog. Raws li cov tswv, ua ntej kev kho dua tshiab, cov mileage yog kwv yees li 300 txhiab km. Tab sis qhov ntsuas no tsis yog qhov txwv, nws tag nrho yog nyob ntawm qhov zoo ntawm cov roj siv, nrog rau kev hloov pauv raws sijhawm.
Tsis zoo li ntau lub cav zoo sib xws los ntawm Nissan, nws yuav tsis yooj yim los nrhiav tus lej cav. Muaj ib qho tshwj xeeb hlau bar nrog cov ntaub ntawv hais txog lub cav naj npawb, nrog rau lwm tus nyob ib sab ntawm lub tshuab hluav taws xob, ntawm lub cam khwb cia hlau thaiv. Nws zoo li no:
Motor kev ntseeg tau
Cov koob ntawm cov cav sib txawv tsis tsuas yog nyob rau hauv nws cov tswj, tab sis kuj nyob rau hauv kev ntseeg tau. Piv txwv li, koj tuaj yeem nrhiav Nissan Terrano hauv kev ua lag luam theem nrab nruab nrog vg series cav nrog ib mais ntawm ntau dua 400 txhiab km. Txawm hais tias qhov sib txawv ntawm vg30de, vg30dett thiab lwm yam qauv ntawm cov koob, lawv txhua tus muaj lub neej ua haujlwm ntev. Cov teeb meem me me hauv qab no tuaj yeem ua tau thaum ua haujlwm:
- thawb thaum hloov los ntawm thawj iav mus rau ob - feem ntau qhov teeb meem nyob rau hauv lub backstage nyob nruab nrab ntawm lub gearbox thiab lub iav qib;
- nce roj noj nyob rau hauv lub voj voog ua ke - yuav tsum tau yaug lub cav, tshwj xeeb tshaj yog nyob rau hauv kev noj haus.
Txij nkawm zoo
Ib qho tseem ceeb kom zoo dua ntawm lub cev muaj zog, txawm tias niaj hnub analogues, yog kev tswj xyuas.
Lub cev muaj zog kuj yooj yim rau disassemble. Cais, nws yuav tsum tau muab sau tseg muaj peev xwm ntawm tus kheej-kev kuaj mob ntawm no lub cev muaj zog. Chav tswj tsis tas yuav tsum muaj kev sib txuas ntawm cov cuab yeej kuaj mob tshwj xeeb. Nws yuav txaus siv qhov yuam kev decoding los ntawm Nissan.
Lub tshuab hluav taws xob yog lub thawv hlau uas muaj lub qhov - nws muaj ob lub LEDs. Lub diode liab qhia kaum, lub ntsuab diode qhia units. Qhov chaw ntawm chav tsev yuav txawv nyob ntawm seb tus qauv ntawm lub tsheb (nyob rau hauv txoj cai ncej, nyob rau hauv tus neeg nrog caij lossis lub rooj tsav tsheb). Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias DOHC system cav tau nruab nrog lub sijhawm siv sijhawm, uas yuav tsum tau hloov kho thiab hloov cov khoom ntawm tus kheej. Kev teeb tsa ntawm txoj siv yuav tsum tau ua nruj me ntsis raws li cov cim.
Yog tias txoj siv tsis raug hloov raws sijhawm thiab nws raug torn, ces cov li qub yuav khoov los ntawm kev cuam tshuam ntawm cov pistons. Yog li ntawd, yuav tsum tau hloov kho lub cav. Thaum hloov lub sij hawm siv, koj yuav tsum tau hloov:
- qhia rollers;
- roj qog ntawm "hauv pliaj";
- qhia rau lub sijhawm tshwj xeeb rubey.
Nws yog ib qho tseem ceeb los xyuas compression. Nws yuav tsum nyob rau hauv qhov ntau ntawm 10 mus rau 11. Yog hais tias nws poob mus rau 6, nws yog ib qhov tsim nyog los sau cov thooj voos kheej kheej nrog roj. Yog tias tom qab ntawd qhov compression tau nce, nws yuav tsum tau hloov lub valve qia seals. Txhawm rau teeb tsa qhov hluav taws xob, koj yuav tsum txuas lub stroboscope. Xav tau kev saib xyuas ntxiv:
- ntsuas kub - yog tias nws ua tsis tau, lub kiv cua txias yuav tsum tsis txhob tig;
- lub teeb liab rau lub tachometer - qhov no yog dab tsi ua rau lub inoperability tom kawg;
- pib txhuam - kev soj ntsuam pom yog tsim nyog.
Nws yog ib qho tseem ceeb kom ncua sij hawm xyuas lub khob sensor. Cov seem ntawm cov khoom siv kuj tseem yuav ua haujlwm. Txwv tsis pub, muaj kev siv roj ntau ntxiv. Tej zaum yuav muaj lwm yam teeb meem ntawm lub cav.
Hom roj zoo li cas
Kev xaiv roj yog ib qho tseem ceeb tshaj plaws. Ib qho kev daws teeb meem zoo tshaj plaws yog Eneos Gran Touring SM. Feem ntau 5W-40, SAE yog siv. Tab sis nws kuj tuaj yeem sau cov roj los ntawm lwm cov tuam txhab, ntawm qhov sib txawv.
Ntau tus siv cov roj qub. Piv txwv li, Nissan 5W-40. Raws li qee tus tswv tsheb, kev siv ZIK ua rau muaj kev siv roj ntau ntxiv. Yog li ntawd, nws siv yog undesirable. Thaum xaiv, nws yog ib qho tseem ceeb kom ua raws li cov neeg tsim khoom cov lus pom zoo.
Daim ntawv teev cov tsheb uas tau teeb tsa
Cov npe ntawm cov tsheb muab nrog cov motors sib xws yog qhov dav heev. Nws suav nrog:
| v 30 e | vg30 ua | vg30 ua | vg 30 turbo |
|---|---|---|---|
| Caravan | Cedric | Cedric | Cedric |
| Cedric | Cedric Cima | Gloria | Fairlady Z |
| Gloria | Fairlady Z | Nissan | Gloria |
| Homie | Gloria | Neeg pleev kob | |
| Maxima | Glory Peak | tsov txaij | |
| tsov txaij |
Nws yuav tsis yooj yim nrhiav hauv Is Taws Nem kev tshuaj xyuas lub cav, ua yeeb yaj kiab ntawm lub koob yees duab video (piv txwv li, sony nex). Qhov no yuav tsum tau ua ua ntej yuav ib lub tsheb nruab nrog lub cav vg30e lossis zoo sib xws. Nws yog ib qho tseem ceeb kom nkag siab txog qhov tshwj xeeb ntawm kev ua haujlwm ntawm cov khoom siv zoo li no. Lub cev muaj zog yog kho tau, cov khoom seem muaj muag. Tab sis tib lub sijhawm, tus nqi ntawm cov khoom yog qhov siab.
