Nissan VQ30DET injini

Mu 1994, "Nissan" adapanga mzere wa sedans kalasi bizinesi. Iwo amapangidwa ndi injini za VQ mndandanda ndi mphamvu yamphamvu ya malita 2, 2.5 ndi 3. Ma motors anali abwino, koma osati angwiro. Nkhawa za ku Japan zinawawongolera pang’onopang’ono. Mwachitsanzo, kuti muchepetse kulemera, chipika chachitsulo chachitsulo chinapangidwa ndi aluminiyamu, ndipo lamba wanthawi yochepa adasinthidwa ndi unyolo, womwe unawonjezera kwambiri moyo wake wautumiki.

Pambuyo pake, wopanga adaganiza zosiya zonyamula ma hydraulic. Izi zinali zofunika kuonjezera kutumizidwa kwa magalimoto kutengera injini iyi kupita kumayiko omwe mafuta amchere otsika komanso otsika mtengo amagwiritsidwa ntchito mwachangu. Kugwiritsa ntchito kwawo pamainjini okhala ndi ma hydraulic compensators kunapangitsa kuti izi zilephereke.

Kenako adakonza njira yolowera ndi kutulutsa, ndikuyika ma camshaft awiri mbali iliyonse ya injini. Zonsezi zinayambitsa kuwonjezeka kwa mphamvu ndi torque ya malo opangira magetsi, ndipo kuwonjezeka kwa zipindazo kunaika mwayi wokakamiza. Zotsatira zake, kusinthidwa kwatsopano kudawonekera - VQ2DET. Iwo ntchito kale mu 30 ndipo ngakhale ntchito pa magalimoto 1995 (Nissan Cima).

Makhalidwe ndi kumasulira kwa dzina

Mayina amitundu ndi mitundu ya injini za Nissan zimamveketsa bwino mawonekedwe awo. Chithunzi cha VQ30DET

1. V - mawonekedwe a kapangidwe (pankhaniyi, tikutanthauza mawonekedwe a V).
2. Q ndi dzina la mndandanda.
3. 30 - voliyumu ya silinda (30 kiyubiki dm. kapena malita atatu).
4. D - mawonekedwe a injini okhala ndi mavavu 4 pa silinda.
5. E - jekeseni wamagetsi amagetsi ambiri.

Izi zimapangitsa kuti zimveke zoyambira zamagalimoto.

Magalimoto okhala ndi injini ya VQ30DET

Kusintha uku kumagwiritsidwa ntchito ndi makina otsatirawa:

1. Nissan Cedric 9 ndi mibadwo 10 - kuchokera 1995 mpaka 2004.
2. Nissan Cima 3-4 mibadwo - kuyambira 1996 mpaka 2010.
3. Nissan Gloria 10-11 mibadwo - kuchokera 1995 mpaka 2004.
4. Nissan Leopard mibadwo 4 - kuyambira 1996 mpaka 2000.

Ambiri mwa magalimoto awa, kuphatikizapo Nissan Cedric 1995, akadali panjira yokhazikika chifukwa chodalirika komanso moyo wautali wa injini.

Nissan Cedric 1995

Neo teknoloji

Mu 1996, nkhawa Mitsubishi anayamba ndipo anayamba kupanga misa injini ndi GDI dongosolo. Mbali ya injini zoyatsira zamkati zotere ndi jakisoni wachindunji wa petulo m'masilinda mopanikizika kwambiri komanso ndi mpweya wambiri wosakanikirana (chiwerengero cha 1:40). Nissan adayesa kupeza mpikisano wake wachindunji komanso adayamba kupanga ukadaulo wofananira wa jakisoni wamafuta. Ma injini angapo okhala ndi jekeseni mwachindunji m'zipinda adalandira mawu oyambira - Neo Di.

Chinthu chachikulu cha dongosolo ndi mkulu kuthamanga mafuta mpope. Chifukwa cha iye, pakuchita zopanda pake, kuthamanga kwa 60 kPa kumapangidwa, ndipo poyendetsa galimoto, kumatha kufika 90-120 kPa.

Injini za banja la DE zakhala zikusintha izi ndipo kuyambira 1999 adaphatikizanso zitsanzo ndiukadaulo wa NEO. Anali ndi ma camshaft osinthidwa komanso nthawi ya valve. Ma motors awa akhala otsogola kwambiri paukadaulo komanso okonda zachilengedwe, koma nthawi yomweyo ntchito yawo idadalira kwambiri kuwongolera zamagetsi. Mphamvu zamagetsi zamagetsi zakhalabe zofanana, koma zotsatira zake zovulaza zachilengedwe zachepa.

Zolakwika ndi zovuta za injini ya VQ30DET

Zinanenedwa pamwambapa kuti kusinthidwa uku kulibe zonyamula ma hydraulic, kotero kamodzi pa makilomita 100 aliwonse m'pofunika kusintha ma valve - ichi ndi mawonekedwe a magetsi.

Pali madandaulo pa intaneti kuchokera kwa eni magalimoto omwe ali ndi ma injini awa okhudza kutuluka kwa mafuta kudzera pa dipstick. Mukayatsa galimoto ndikuyang'ana kuchuluka kwa mafuta, ndodo yonse imatha kukhala ndi mafuta. Pa liwiro lalikulu (5-6 zikwi rpm), kulavulira kuchokera ku kafukufuku ndikotheka.

Panthawi imodzimodziyo, galimotoyo imayenda bwino ndipo sichiwotcha, komabe, mlingo wa mafuta umatsika, womwe m'tsogolomu umadzaza ndi njala ya mafuta. Amakhulupirira kuti chifukwa chake chikhoza kukhala mpweya mu crankcase, womwe umalowa mkati mwa masilinda. Izi zikutanthauza kuti mwina masilinda atha, kapena mphete. A vuto ofanana sizichitika kawirikawiri, koma pa injini VQ30 (ndi zosintha zake) ndi mtunda olimba.

Zowopsa zina zamainjini awa:

1. Kuphwanya gawo logawa gasi.
2. Detonation, yomwe nthawi zambiri imatsagana ndi kuchuluka kwa mafuta. Pofuna kuthetsa vutoli, kuyeretsa mavavu kuchokera ku mwaye kumafunika.
3. Masensa olakwika a MAF (mamita mpweya wambiri), zomwe zimapangitsa kuti injini idye mpweya wambiri - izi zimapanga kusakaniza kowonda kwambiri.
4. Kutaya mphamvu mu dongosolo mafuta. Zina mwazinthu zake zimatha kukhala zosagwiritsidwa ntchito - pampu ya jakisoni, zosefera, zowongolera kuthamanga.
5. Majekeseni osagwira ntchito.
6. Kulephera kwa zolimbikitsa, zomwe zimaphatikizapo kutaya mphamvu.

Nthawi zambiri, eni magalimoto okhala ndi mainjiniwa amalumikizana ndi siteshoni ndi kudandaula za kuwala kwa Check Engine. Kuyenda kosatha kapena kwakanthawi sikumachotsedwa (pamene imodzi mwa masilindala sagwira ntchito bwino kapena osagwira ntchito konse), zomwe zimaphatikizidwa ndi kutaya mphamvu.

Nthawi zambiri izi zimagwirizanitsidwa ndi vuto mu dongosolo loyatsira. Ngati "ubongo" umayang'ana momwe ma coil amagwirira ntchito ndikuzindikira kuti palibe vuto lililonse, amadziwitsa dalaivala za izi pogwiritsa ntchito kuwala kwa Injini.

Pankhaniyi, cholakwika P1320 chikuwerengedwa. Tsoka ilo, muyenera kudziwa pamanja kuti koyilo iti sikugwira ntchito, yomwe ndi cholakwika mu dongosolo la matenda a injini.

Ma injini okhala ndi ukadaulo wa Neo amagwiritsa ntchito ma valve a EGR, omwe amachepetsa kuchuluka kwa ma nitrogen oxide mumipweya yotulutsa mpweya. Chipangizochi ndi chamtengo wapatali komanso chimafuna mafuta apamwamba kwambiri. Mukamagwiritsa ntchito mafuta otsika kwambiri (m'dziko lathu, mtundu wa petulo ndi wotsika poyerekeza ndi mafuta ku Europe), valavu imatha kuphimbidwa ndi mwaye ndi mphero. M'chigawochi, sichigwira ntchito, kotero kusakaniza kwamafuta-mpweya komwe kumaperekedwa kumasilinda kumakhala kolakwika. Izi zimaphatikizapo kuchepa kwa mphamvu, kuchuluka kwa mtunda wa gasi komanso kuvala mwachangu kwa injini. Nthawi yomweyo, kuwala kwa injini ya Check pa dashboard kumayatsa. Dziwani kuti valavu ya EGR ndi vuto la injini zambiri komwe imagwiritsidwa ntchito, osati makamaka pa injini za VQ30DE.

Pomaliza

Injini iyi imasonkhanitsa ndemanga zabwino pakati pa eni galimoto - ndizosasamala pakukonza, zodalirika, komanso zofunika kwambiri - zolimba. Mutha kutsimikizira nokha poyang'ana malo ogulitsa magalimoto ogwiritsidwa ntchito. Pali zitsanzo za "Nissan Cedric" ndi "Cima" za 1994-1995 pa odometer ndi makilomita oposa 250-300 zikwi. Pankhaniyi, mukhoza kuwonjezera deta pa chipangizo, chifukwa ogulitsa nthawi zambiri amapotoza "ovomerezeka" mtunda.
