Nissan VQ25HR cav
Nissan VQ25HR yog 2.5-liter engine, uas yog tus yau tshaj nyob rau hauv HR tsev neeg thiab yog ib tug V-shaped 6-lub tog raj kheej unit. Nws tau tshwm sim nyob rau xyoo 2006, tau txais lub forged crankshaft thiab txuas rods, lub sij hawm saw tsav, thiab tau ua tsis muaj hydraulic compensators.
Yog li ntawd, yuav tsum tau kho cov li qub.
Qhov no yog ib tug tshiab lub cev muaj zog nrog cov yam ntxwv nta ntawm series:
- eVTC system ntawm ob lub ncej.
- Extended txuas rods thiab ib lub tog raj kheej siab thaiv.
- Molybdenum coated pistons.
- Pushers ua tiav raws li cov cuab yeej tshwj xeeb tsis muaj hydrogen.
tsis
Cov yam ntxwv tseem ceeb ntawm lub cev muaj zog sib haum rau lub rooj:

Obviously, qhov no yog ib tug haib technologies engine nrog ib tug muaj peev xwm.
Tsheb nrog VQ25HR cav
Lub tshuab Japanese tau nruab rau ntawm cov tshuab hauv qab no:
- Nissan Fuga - los ntawm 2006 mus rau hnub no.
- Nissan Skyline - los ntawm 2006 mus rau tam sim no hnub.
- Infinity G25 - 2010-2012 xyoo.
- Infinity EX25 - 2010-2012 TSI
- Infinity M25 - 2012-2013 TSI
- Infinity Q70 - 2013-tam sim no
- Mitsubishi Proudia 2012-qhov rooj hatchback XNUMX.
Lub cev muaj zog tau tshwm sim nyob rau hauv 2006 thiab nyob rau hauv nruab nrab ntawm 2018 yog ntsia rau cov qauv tshiab ntawm cov thawj Japanese kev txhawj xeeb, uas tau lees tias nws kev ntseeg siab, manufacturability thiab zoo.
Ua haujlwm
VQ25HR yog lub cav muaj zog nrog lub zog siab tshaj plaws ntawm kev kub ceev. Qhov no txhais tau hais tias lub cev muaj zog yuav tsum tau tig thiab tsis "txuas" ntawm qhov ceev ceev hauv cheeb tsam ntawm 2000 rpm, raws li ntau tus neeg tsav tsheb ua. Yog tias koj niaj hnub ua haujlwm ntawm lub cav combustion ntawm qhov qis qis, ces coking yog ua tau, uas yuav ua rau muaj qhov tshwm sim ntawm cov roj scraper rings. Qhov no yuav tshwm sim los ntawm kev siv roj ntau, yog li nws yog qhov tsim nyog los tswj nws qib tom qab 100 txhiab kilometers.
Raws li cov tswv, lub sij hawm cov saw tsis nplhaib tom qab 100 txhiab kilometers (cov chaw tsim tshuaj paus pom zoo kom hloov nws tom qab 200-250 txhiab km.), thiab tus nqi ntawm hloov nws yog tsawg, uas kuj yog ib tug ntxiv. Ib txheej ntawm thawj chains thiab tensioners yuav raug nqi 8-10 txhiab rubles.
Kev siv roj av siab heev. Thaum lub caij ntuj no, nrog kev tsav tsheb hnyav, lub cav "noj" 16 litres roj, lossis ntau dua.
Nws yog tsim nyog xav tias lub cav nyiam ceev, thiab nws yuav tsum tau untwisted, yog li kev noj ntau dua. Thaum tsav tsheb nyob rau hauv txoj kev loj, roj av noj yog 10 litres ib puas, uas yog ib tug txaus tshwm sim rau ib tug haib 2.5-liter chav tsev.
Teeb meem
Txawm hais tias qhov tseeb tias VQ25HR lub cav muaj kev ntseeg siab thiab muaj peev txheej siab, nws tau txais qee qhov teeb meem:
- Tshaj kub. Kev ua haujlwm ntev ntawm kev kub ceev heev tuaj yeem ua rau overheating. Qhov no feem ntau yuav tho lub tog raj kheej taub hau gaskets. Yog li ntawd, antifreeze yuav nkag mus rau hauv combustion chambers.
- Kev ua luam dej ceev thiab tsis ruaj khov ua haujlwm ntawm lub tshuab hluav taws xob sab hauv, uas yog tshwm sim los ntawm extrusion ntawm roj channel gaskets. Qhov yuam kev sib thooj yuav tshwm sim ntawm lub dashboard.
- Kev siv roj ntau ntxiv. Qhov ua rau ntawm cov roj burner tom qab kaum tawm txhiab kilometers yuav coking ntawm lub cav. Yog li ntawd, cov roj scraper rings yuav tsis ua hauj lwm zoo vim muaj cov pa roj carbon ntau ntau.
- Kev qaug dab peg ntawm lub tog raj kheej phab ntsa. Hauv kev siv tshuab, scuffs tshwm rau ntawm lub tog raj kheej phab ntsa. Yog vim li cas rau lawv cov tsos yog ingress mus rau hauv lub combustion chambers ntawm qhov chaw ntawm lub catalytic converter, uas nkag mus rau ntawd thaum lub li qub raug kaw. Tias yog vim li cas cov tswv feem ntau tshem tawm ib feem ntawm cov catalyst uas nyob ze ntawm lub qhov hluav taws xob.
Txhawm rau kom ua tiav, VQ25HR yog lub cav muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo hauv Nyij Pooj uas tsis muaj kev suav tsis raug thiab qhov tsis txaus uas ua rau muaj teeb meem thoob ntiaj teb. Yog li ntawd, nrog kev saib xyuas raws sijhawm thiab tsim nyog, lub cav yuav "khiav" 200 txhiab mais yam tsis muaj kev puas tsuaj.
Kev lag luam thib ob
Daim ntawv cog lus motors VQ25HR raug muag ntawm qhov chaw tsim nyog. Lawv tus nqi nyob ntawm seb qhov hnav, mais, qhov xwm txheej. Cov chav tsis ua haujlwm "rau cov khoom seem" raug muag rau 20-25 txhiab rubles, cov tshuab ua haujlwm tuaj yeem yuav rau 45-100 txhiab rubles. Tau kawg, tus nqi ntawm cov tshuab tshiab tso tawm tsis ntev los no yog ntau dua.
