Nissan VQ25HR injini
Nissan VQ25HR ndi injini ya 2.5-lita, yomwe ndi yaing'ono kwambiri m'banja la HR ndipo ili ndi mawonekedwe a V-6-cylinder unit. Idawonekera mu 2006, idalandira crankshaft yopangidwa ndi ndodo zolumikizira, chowongolera nthawi, ndipo idapangidwa popanda ma compensators a hydraulic.
Choncho, pakufunika kusintha ma valve.
Iyi ndi injini yatsopano yomwe ili ndi mawonekedwe a mndandanda:
- eVTC system pazitsulo ziwiri.
- Ndodo zolumikizira zowonjezera ndi cylinder block yayitali.
- Ma pistoni okhala ndi molybdenum.
- Okankha amakonzedwa molingana ndi ukadaulo wapadera wopanda haidrojeni.

Mwachiwonekere, iyi ndi injini yamphamvu yaukadaulo yokhala ndi zida zapamwamba.
Magalimoto okhala ndi injini ya VQ25HR
Injini yaku Japan idayikidwa pamakina otsatirawa:
- Nissan Fuga - kuyambira 2006 mpaka lero.
- Nissan Skyline - kuyambira 2006 mpaka lero.
- Infinity G25 - 2010-2012
- Infinity EX25 - 2010-2012
- Infinity M25 - 2012-2013
- Infinity Q70 - 2013-panopa
- Mitsubishi Proudia - 2012-н.в.
Galimotoyo inawonekera mu 2006 ndipo pakati pa 2018 imayikidwa pa zitsanzo zatsopano za kutsogolera ku Japan, zomwe zimatsimikizira kudalirika kwake, kupanga kwake komanso khalidwe.
Ntchito
VQ25HR ndi injini yamphamvu yokhala ndi torque yayikulu kwambiri. Izi zikutanthauza kuti galimoto iyenera kutembenuzidwa osati "kukokera" pa liwiro lotsika m'dera la 2000 rpm, monga momwe madalaivala ambiri amachitira. Ngati mumagwiritsa ntchito injini yoyaka mkati nthawi zonse pa liwiro lotsika, ndiye kuti kuphika ndi kotheka, zomwe zingapangitse kuti pakhale mphete zamafuta. Izi zidzawonekera kuchokera ku mafuta ambiri, choncho m'pofunika kuwongolera mwadongosolo mlingo wake pambuyo pa makilomita 100 zikwi.
Malinga ndi eni ake, unyolo wanthawi sulira pambuyo pa mtunda wa makilomita 100 (wopanga amalimbikitsa kuti asinthe pambuyo pa 200-250 km). Seti ya maunyolo oyambilira ndi ovutikira adzawononga ma ruble 8-10.
Mafuta a petulo ndiwokwera kwambiri. M'nyengo yozizira, ndi kuyendetsa mwaukali injini "imadya" malita 16 a mafuta, kapena kuposa.
Ndikoyenera kuganizira kuti injini imakonda kuthamanga, ndipo iyenera kukhala yosasunthika mwamphamvu, chifukwa chake kumwa kumakhala kwakukulu. Poyendetsa mumsewu waukulu, kugwiritsa ntchito mafuta ndi malita 10 pa zana, zomwe ndi zotsatira zovomerezeka pagawo lamphamvu la 2.5-lita.
Mavuto
Ngakhale kuti injini VQ25HR ndi odalirika ndi gwero mkulu, analandira mavuto:
- Kutentha kwambiri. Kugwira ntchito nthawi yayitali pa liwiro lalikulu kwambiri kungayambitse kutenthedwa. Izi ndizotheka kuboola ma cylinder head gaskets. Zotsatira zake, antifreeze idzalowa m'zipinda zoyaka moto.
- Kuthamanga kwa kusambira komanso kugwira ntchito kosakhazikika kwa injini yoyaka mkati, yomwe imayamba chifukwa cha ma gaskets otulutsa mafuta. Cholakwika chofananira chidzawonekera pa dashboard.
- Kuchulukitsa kugwiritsa ntchito mafuta. Choyambitsa chowotcha mafuta pambuyo pa makumi masauzande a kilomita chidzakhala coking injini. Chotsatira chake, mphete za mafuta opangira mafuta sizidzagwiranso ntchito bwino chifukwa cha kuchuluka kwa carbon deposits.
- Zowonongeka pamakoma a silinda. M'mainjini ogwiritsidwa ntchito, ma scuffs amawonekera pamakoma a silinda. Chifukwa cha maonekedwe awo ndi kulowa m'zipinda zoyaka moto za zigawo za catalytic converter, zomwe zimawoneka pamenepo pamene ma valve atsekedwa. Ndicho chifukwa chake eni ake nthawi zambiri amachotsa mbali ya chothandizira yomwe ili pafupi ndi malo otulukira.
Mwachidule, VQ25HR ndi injini yodalirika komanso yapamwamba kwambiri yaku Japan yomwe ilibe zolakwika komanso zolakwika zomwe zimadzetsa mavuto padziko lonse lapansi. Choncho, ndi kukonza kwake ndi koyenera, injini "idzathamanga" makilomita 200 zikwi popanda kuwonongeka.
Msika wachiwiri
Ma contract motors VQ25HR amagulitsidwa pamalo oyenera. Mtengo wawo umadalira kuchuluka kwa kuvala, mtunda, chikhalidwe. Magawo osagwira ntchito "opuma" amagulitsidwa ma ruble 20-25, injini zogwirira ntchito zitha kugulidwa kwa ma ruble 45-100. Inde, mtengo wa injini zatsopano zomwe zatulutsidwa posachedwa ndizokwera kwambiri.
