Nissan QD32 cav

Lub 4-lub tog raj kheej diesel cav Nissan QD32 nrog ib tug ntim ntawm 3153 cm3 tau tsim txij li thaum nruab nrab-90s ntawm lub xyoo pua xeem los ntawm ib tug ntawm cov loj tshaj plaws manufacturers, lub Japanese tsheb tuam txhab uas muag Nissan Motor Co., Ltd. Technically, ib chav tsev siab dua hloov TD series xyaw.

Txawm li cas los xij, twb nyob rau thaum ntxov 2000s, nws tau hloov los ntawm ZD xyaw, tshwj xeeb tshaj yog ZD-30. Hauv kev cim, thawj ob tsab ntawv qhia cov koob, cov lej 32 qhia qhov ntim hauv deciliters. Lub uniqueness ntawm chav tsev yog hais tias nyob rau hauv tag nrho cov keeb kwm ntawm lub hom, tsuas yog ob peb series (ED, UD, FD) ntawm sab hauv combustion engines (ICE) muaj ib tug zoo xws li cov ntim ntawm roj combustion chambers.

QD32 diesel cav tau npaj los muab cov kev lag luam minibuses, hnyav SUVs, tsheb thauj khoom thiab cov cuab yeej tshwj xeeb. Hauv ntau yam kev hloov kho thiab khoom siv, lawv tau nruab nrog cov qauv xws li Nissan Homy, Nissan Caravan, Datsun Truck, Nissan Atlas (Atlas), Nissan Terrano (Terrano) thiab Nissan Elgrand (Elgrand).

nta

Ib qho tseem ceeb ntawm QD32 diesel chav tsev yog tias nws tsis muaj ib qho kev tsheb ciav hlau sib xyaw ua ke. Thaum lub sij hawm txoj kev loj hlob ntawm lub cav, qhov no system yog heev ntau. Txawm li cas los xij, lub tuam txhab engineers txhob txwm tsis qhia nws rau hauv lub cav. Yog vim li cas yog hais tias ib tug yooj yim lub cev muaj zog ntaus ntawv tso cai rau koj mus nqa tawm kho nyob rau hauv lub teb nrog improvised txhais tau tias, nyob rau hauv tsis muaj kev pab cuam lub tsheb, nrog koj tus kheej txhais tes.

Ua ke nrog lub sij hawm tsav tsheb, uas tshem tawm qhov teeb meem ntawm kev sib cuam tshuam ntawm lub valve thiab lub piston, thiab lub tog raj kheej lub taub hau ua los ntawm cam khwb cia hlau, qhov no ua rau muaj kev ntseeg siab thiab kev pab lub neej ntev ntawm chav tsev tag nrho. Ua tsaug rau qhov no, ntawm cov neeg, lub cav tau txais cov xwm txheej ntawm "indestructible" los ntawm cov tswv tsheb. Tsis tas li ntawd, QD32 tau paub zoo ntawm cov tuners pib hloov lub tsheb thawj lub cav nrog ib qho yooj yim, pheej yig dua thiab ruaj khov dua.

Txuas ntxiv

Nyob ntawm kev teeb tsa nrog ib lossis lwm hom kev txhaj tshuaj twj tso kua mis, lub zog ntawm lub cav tuaj yeem sib txawv:

1. Nrog ib tug neeg kho tshuab tsav (mechanical txhaj twj tso kua mis) - 135 l ntawm ib tug torque ntawm 330 Nm.
2. Nrog hluav taws xob tsav - 150 liters. Nrog thiab torque ntawm 350 Nm.

Thawj hom, raws li txoj cai, tau nruab nrog cov tsheb thauj khoom, thiab thib ob - nrog minivans. Nyob rau tib lub sijhawm, hauv kev xyaum, nws tau pom tias cov neeg kho tshuab muaj kev ntseeg siab dua li cov khoom siv hluav taws xob, tab sis tsis yooj yim rau siv.

QD32 cav hloov kho

Thaum lub sijhawm tsim khoom ntawm 11 xyoo, lub tshuab hluav taws xob diesel tau tsim nyob rau hauv 6 kev hloov kho kom haum rau cov qauv tsheb sib txawv.

Hloov kho, xyoo	Kev txhawb cov ntsiab lus	Tsheb qauv, gearbox (gearbox)
QD321, 1996 - 2001	Torque 221 Nm ntawm 2000 rpm, lub zog - 100 hp Nrog.	Nissan Homy thiab Nissan Caravan, tsis siv neeg
QD322, 1996-2001	Torque 209 Nm ntawm 2000 rpm, lub zog - 100 hp Nrog	Nissan Homy thiab Nissan Caravan, phau ntawv kis tau tus mob (MT)
QD323, 1997-2002	Torque 221 Nm ntawm 2000 rpm, lub zog - 110 hp Nrog	Datsun tsheb, phau ntawv / tsis siv neeg (tsis siv neeg kis tau tus mob)
QD324, 1997-2004	Torque 221 Nm ntawm 2000 rpm, 105 hp	Nissan Atlas, tsis siv neeg
QD325, 2004-2007	Torque 216 Nm ntawm 2000 rpm, lub zog - 98 hp Nrog.	Nissan Atlas (European qauv), tsis siv neeg
QD32ETi, 1997-1999	Torque 333 Nm ntawm 2000 rpm, lub zog - 150 hp Nrog.	Nissan Terrano (RPM system), Nissan Elgrand, tsis siv neeg

Kev hloov kho ntawm QD32ETi thaiv yog qhov txawv ntawm qhov seem. Ua ntej ntawm tag nrho cov, nws txawv ntawm tus qauv version nrog ib tug intercooler thiab ib tug sib txawv tsim ntawm collectors nrog tib ntim.

Qhov zoo thiab qhov tsis zoo

Qhov pom tseeb zoo ntawm QD32 tsav suav nrog:

• OHV lub sijhawm teem sijhawm, tsis suav nrog cov saw lossis siv txoj hlua tawg / dhia.
• Robust, compact thiab txhim khu kev qha lub cev muaj zog tsim.
• Muaj peev xwm ua haujlwm nrog thiab tus nqi qis.
• Kev ruaj ntseg siab txawm tias nrog koj tus kheej txhais tes.
• Kev sib tsoo ntawm pistons thiab lub tog raj kheej yog tshem tawm tag nrho los ntawm kev siv lub tsheb ciav hlau.

Lub cav kuj muaj qhov tsis zoo:

• Tsawg zog.
• Suab nrov.
• Inertia.
• Tsis muaj 4-valve cylinders.
• Lub impossibility ntawm kev siv ntau niaj hnub channel ntawm cov tswv yim / tso zis txoj kev.

Cov qauv tsheb uas lub cav QD32 tau teeb tsa

Lub QD32 aspirated tau ntsia feem ntau ntawm Nissan tsheb thiab ib qho qauv ntawm Datsun Truck kab (1997-2002):

• Homy / Caravan minivan los ntawm 1996 txog 2002.
• Atlas coj mus muag tsheb los ntawm 1997 txog 2007

Kev hloov kho turbocharged ntawm QD32ETi chav tsev tau teeb tsa ntawm cov tshuab hauv qab no:

• Minivan Elgrand nrog rear-log tsav layout.
• Tag nrho-log tsav SUV Regulus.
• Tsheb-log tsav tag nrho-log tsav layout ntawm Terrano SUV.

Txij nkawm zoo

QD32 lub cav diesel tag nrho, raws li kev tshuaj xyuas, suav tias yog qhov txhim khu kev qha thiab "indestructible" txawm tias nyob rau hauv kev ua haujlwm nyuaj tshaj plaws thiab tsis zoo rau qhov zoo ntawm cov roj diesel thiab roj. Txawm li cas los xij, sai lossis tom qab lub disk yuav ua tsis tiav. Yog li ntawd, txhua tus neeg tsav tsheb yuav tsum paub tias cov tsos mob ua haujlwm tsis zoo cuam tshuam rau qhov ua rau lub cav tsis ua haujlwm.

Yuav ua li cas thiaj li kuaj tus kheej lub cev muaj zog (phau ntawv)

Txhawm rau ua qhov kev kuaj mob tus kheej ntawm QD32 lub cav, koj yuav tsum xub nrhiav lub qhov (socket) kuaj mob. Raws li txoj cai, nws yog nyob rau hauv lub kauj kem (7 qhov nyob rau hauv ob kab). Ua ntej pib qhov kev kuaj mob, nws yog ib qho tsim nyog yuav tsum txav lub oob khab mus rau "ON" txoj hauj lwm yam tsis tau pib lub cav.

Tom qab ntawd, siv daim ntawv clip, koj yuav tsum kaw cov neeg sib cuag n. 8 i nr. 9 ntawm qhov txuas (thaum saib ntawm sab laug mus rau sab xis, cov no yog thawj ob qhov nyob hauv kab hauv qab). Cov neeg raug kaw tsuas yog ob peb feeb xwb. Clamp tshem tawm, CHECK qhov taw qhia yuav tsum flash.

Koj yuav tsum suav cov naj npawb ntev thiab luv blinks. Nyob rau hauv cov ntaub ntawv no, ntev blinks txhais tau tias kaum, thiab luv blinks txhais tau hais tias ib tug nyob rau hauv lub encryption ntawm tus kheej-kuaj code. Piv txwv li, 5 ntev thiab 5 luv flashes ua raws li 55. Qhov no txhais tau hais tias tsis muaj lub cav ua haujlwm tsis zoo. Txhawm rau rov pib qhov kev kuaj mob tus kheej, koj yuav tsum ua raws li cov lus piav qhia ntawm kev ua dua.

Piv txwv li, ntawm no yog ib lub rooj ntawm kev kuaj tus kheej cov lej rau QD32ETi cav.

Kev tiv thaiv kev tawg - Lub Sijhawm Saib Xyuas

Tsis tsuas yog ua tib zoo ua haujlwm, tab sis kuj tseem ntsuas kev saib xyuas raws sijhawm yuav pab txuas ntxiv lub neej ntawm QD32 diesel cav thiab tiv thaiv nws qhov kev puas tsuaj. Chaw tsim tshuaj paus Nissan tau teem sijhawm cov kev pabcuam hauv qab no rau nws cov xeeb ntxwv:

1. Hloov cov roj lim txhua 40 txhiab kilometers.
2. Kev kho cov txheej txheem thermal li qub txhua 30 txhiab kilometers.
3. Hloov cov roj cav, nrog rau cov roj lim tom qab kev khiav ntawm 7,5 txhiab km.
4. Ntxuav lub crankcase cua tshuab ib zaug txhua 1 xyoos.
5. Hloov cov lim cua txhua 20 txhiab kilometers.
6. Antifreeze hloov tshiab txhua 40 txhiab kilometers.
7. Hloov cov pa tawm manifold tom qab 60 txhiab kilometers.
8. Cov tswm ciab yuav tsum tau hloov tom qab dhau 20 txhiab kilometers.

Tuning QD32

Lub hom phiaj tseem ceeb ntawm QD32 lub cev muaj zog, tso los ntawm cov chaw tsim khoom, raug txo kom muaj zog, txhim khu kev qha thiab nyab xeeb. Xws li kev ruaj ntseg yog tsim nyog, piv txwv li, rau kev lag luam vans. Txawm li cas los xij, cov neeg uas yuav tsum tau yuam kev tawm ntawm txoj kev lossis tsuas yog xav nyem lub zog siab tshaj plaws ntawm lub tsev yuav tsum ua qhov tsawg kawg nkaus tsim nyog lub cav tuning.

Txhawm rau nce lub zog thiab lub zog ntawm QD32 lub cav, cov kev ntsuas hauv qab no yuav tsum tau ua:

1. Hloov cov injectors nrog cov txiaj ntsig zoo dua.
2. Nruab ib daim ntawv cog lus turbine nrog ib tug pressurization system ntawm 1,2 atmospheres.
3. Txhawm rau txhim kho lub tshuab hluav taws xob ntawm lub twj tso kua mis txhaj tshuaj mus rau ib qho kev siv tshuab.
4. Nruab lub siab siab roj twj tso kua mis thiab injectors rau lub bracket.
5. Flash computer tswj software.

Thaum txhim kho chav tsev fais fab, peb yuav tsum tsis txhob hnov ​​​​qab tias qhov no ua rau cov khoom thauj ntawm lub chassis ntawm lub tsheb thiab nws cov kev ruaj ntseg system. Kev saib xyuas tshwj xeeb yuav tsum tau them rau lub nres kaw lus, lub cav mounts thiab nres nres / discs. Lub cav QD32 feem ntau rov nruab nrog cov qauv hauv tsev (UAZ, Gazelle).
