Thaum twg los hloov lub txim taws rau Qashqai?

Tus thawj iridium spark plug electrode yuav tsum muaj qhov vuam no

Kev ua raws li lub Hoobkas cov cai rau kev hloov lub txim hluav taws xob ntawm Nissan Qashqai yuav txo cov khoom siv tsis ua haujlwm, nrog rau xyuas kom muaj qhov sib xyaw ntawm huab cua-roj sib tov. Rau Nissan Qashqai nrog 1,6 thiab 2,0 liter petrol xyaw, cov chaw tsim tshuaj paus pom zoo kom hloov lub txim plugs txhua txhua 30 km los yog txhua ob xyoos. Kev paub qhia tau hais tias Nissan Qashqai lub Hoobkas hluav taws xob ua haujlwm txog 000 km. Cov cim qhia ntawm malfunction yog raws li nram no:

• deterioration nyob rau hauv lub tsheb dynamics;
• pib lub cav ntev;
• lub cev muaj zog trot;
• cuam ​​tshuam nyob rau hauv lub lag luam ntawm lub internal combustion engine;
• nce roj noj.

Nws tsis yooj yim kom paub qhov txawv ntawm ib qho cuav los ntawm kev ntim khoom

Yog tias cov teeb meem no tshwm sim, hloov lub txim taws. Yog hais tias lub malfunctions tsis yog tshwm sim los ntawm teeb meem nyob rau hauv lwm yam engine Cheebtsam. Nyob rau tib lub sijhawm, txhua qhov hluav taws xob rau Nissan Qashqai yuav tsum tau hloov tam sim ntawd, ob qho tib si thaum lub sijhawm teem sijhawm thiab tsis tau teem sijhawm hloov.

Qhov tswm ciab xaiv rau Nissan Qashqai?

Nissan Qashqai J10 thiab J11 powertrains siv lub txim hluav taws xob nrog cov lus qhia hauv qab no:

• xov ntev - 26,5 mm;
• melting naj npawb - 6;
• txoj kab uas hla - 12 mm.

Cov khoom siv nrog platinum lossis iridium electrodes muaj peev xwm ntev dua. NGK spark plugs nrog ib feem naj npawb 22401-SK81B yog siv los ntawm lub hoobkas. Nws raug nquahu kom siv Denso (22401-JD01B) lossis Denso FXE20HR11 nruab nrog iridium electrode ua lub ntsiab analogue muab los ntawm lub Hoobkas cov lus qhia.

Thaum muas ib tug thawj tswm ciab rau Nissan Qashqai hwj chim units, nws yog ib qho yooj yim khiav mus rau hauv ib tug fake.

NGK muaj ib qho analogue ntawm lub Hoobkas khoom, tab sis nrog ib tug tseem ceeb sib txawv ntawm tus nqi - NGK5118 (PLZKAR6A-11).

Koj tseem tuaj yeem siv cov kev xaiv hauv qab no:

• Bosch cov khoom uas muaj platinum electrode - 0242135524;
• Champion OE207 - cov khoom siv electrode - platinum;
• Denso Iridium Tough VFXEH20 - cov electrodes siv ua ke ntawm platinum thiab iridium;
• Beru Z325 nrog platinum electrode.

Cov cuab yeej rau kev hloov tus kheej ntawm cov tswm ciab thiab cov yam ntxwv ntawm cov txheej txheem

Peb disassemble cov hniav molding, tshem tawm cov yeeb nkab

Koj tuaj yeem hloov lub txim taws rau Nissan Qashqai koj tus kheej, thiab koj yuav tsum tau rhuav tshem ntau cov nodes. Txhawm rau ua qhov no, koj yuav tsum npaj cov cuab yeej thiab cov ntaub ntawv hauv qab no:

• lub nplhaib thiab lub qhov (socket wrenches) rau 8, 10 nrog lub ratchet thiab txuas txuas;
• tiaj tus hau ntswj;
• tswm ciab 14;
• ciaj ntswj;
• tshiab spark plugs;
• throttle gasket thiab intake manifold;
• daim ntaub huv.

Txhawm rau pab txhawb kev hloov ntawm Nissan Qashqai lub zog, nws yog qhov zoo dua los siv lub tshuab hluav taws xob txuas nrog cov hlau nplaum. Nyob rau hauv lawv qhov tsis muaj, ignition coils tuaj yeem siv los tshem tawm thiab nruab cov ntsaws ntsaws. Nws raug nquahu kom hloov cov ntsiab lus ib zaug. Qhov no yuav txo qhov muaj feem ntawm cov khoom txawv teb chaws nkag mus rau hauv lub tog raj kheej.

Peb unscrew lub manifold mounting bolts, disconnect cov ntshav valve connector, unscrew lub throttle valve.

Kev siv lub torque wrench yog tsim nyog los tiv thaiv lub torque ntawm lub txim plugs, throttle lub cev mountings thiab intake manifold. Yog tias muaj kev tso cai ntau dhau, cov yas lossis lub tog raj kheej lub taub hau yuav raug puas tsuaj.

Cov lus piav qhia ntxaws txog yuav hloov Nissan Qashqai tswm ciab nrog koj tus kheej txhais tes

Nyob rau hauv cov ntaub ntawv Qashqai sails ntxiv lawv tus kheej, nws raug nquahu kom siv lub koob yees duab los sau cov kev nqis tes ua ib kauj ruam. Qhov no yuav ua kom yooj yim cov txheej txheem ntawm reassembling yav tas los dismantled powertrain Cheebtsam.

Kev hloov ntawm cov hluav taws xob hluav taws xob hauv Nissan Qashqai lub zog nrog lub ntim ntawm 1,6 thiab 2 litres yog ua raws li cov tswv yim zoo ib yam, tsis hais lub cim ntawm lub tsheb.

Muab zais tom qab lub throttle valve yog lub xya manifold mounting ntsia liaj qhov rooj.

Hloov txheej txheem

• Ua ntej pib ua haujlwm, nws yog ib qho tsim nyog yuav tsum tso cai rau lub hwj chim kom txias;
• Peb disassemble cov hniav yas npog ntawm lub cav combustion, tsau nrog ob bolts;
• Tom ntej no, cov pa cua raug tshem tawm, uas yog mounted nruab nrab ntawm lub cua lim vaj tse thiab lub throttle los ua ke. Ua li no, cov clamps tuav cov cua lim thiab crankcase cua raws li loosened ntawm ob sab;
• Nyob rau theem tom ntej, lub DZ yog dismantled. Ua li no, plaub mounting bolts yog unscrewed, ib tug ntawm lawv yog nyob rau hauv lub shock absorber. Nyob rau hauv lub neej yav tom ntej, tag nrho cov kev sib dhos yog muab tshem tawm mus rau sab yam tsis muaj disconnecting lub hwj chim cables thiab cua txias system;
• Tshem cov roj theem dipstick los ntawm nws lub qhov (socket), npog lub qhov nrog ib daim ntaub qhwv. Qhov no yuav tiv thaiv cov khib nyiab los ntawm kev nkag mus rau hauv lub cav combustion;

Nws yog qhov zoo dua los npog cov qhov hauv lub taub hau ntawm qhov thaiv nrog ib yam dab tsi, tshem cov coils, tshem cov tswm ciab, muab tso rau hauv cov tshiab, tig nrog lub torque wrench.

• Lub intake manifold yog disassembled, uas yog fastened nrog xya screws. Nws raug nquahu kom pib los ntawm unscrewing lub hauv paus ntsia liaj qhov rooj nyob rau pem hauv ntej ntawm lub manifold, thiab ces unscrew plaub ntxiv fasteners. Lub hau yas rov qab yog txuas nrog ob lub bolts. Ib qho yog nyob rau ntawm qhov chaw throttle valve installation, thiab qhov thib ob yog nyob rau sab laug thiab txuas los ntawm lub bracket. Tom qab tshem tawm tag nrho cov fasteners, lub intake manifold yog ua tib zoo nqa thiab tso tseg yam tsis muaj kev cuam tshuam cov kav dej;
• Lub chaw teeb tsa ntawm cov khoom noj khoom haus tau raug ntxuav kom huv si ntawm cov av thiab plua plav, lub qhov hauv lub tog raj kheej lub taub hau yog pre-kaw nrog rags;
• Tom ntej no, lub hwj chim cables raug txiav thiab lub ignition coil mounting bolts yog unscrewed, uas tso cai rau koj tshem tawm cov khoom siv;
• Cov tswm ciab tawg nrog kev pab ntawm ib tug tswm ciab. Tom qab ntawd, tag nrho cov av tsaws yog wiped nrog rags, yog hais tias muaj ib tug compressor, nws yog zoo dua rau tshuab nws nrog compressed cua;
• Nyob rau hauv lub neej yav tom ntej, alternated tshem tawm thiab nruab tshiab spark plugs. Nyob rau hauv rooj plaub no, nws yog ib qho tsim nyog yuav tsum ua tib zoo ntxig rau hauv lub rooj zaum kom tsis txhob cuam tshuam qhov sib txawv ntawm interelectrode. Lub zog nruj ntawm cov khoom tshiab yuav tsum nyob rau hauv thaj tsam ntawm 19 txog 20 N * m;
• Nyob rau hauv lub neej yav tom ntej, lub dismantled units yog ntsia nyob rau hauv lub rov qab kev txiav txim, siv tshiab gaskets. Nyob rau hauv cov ntaub ntawv no, thaum nruj lub mounting bolts, nws yog tsim nyog los tiv thaiv cov nram qab no quab yuam: intake manifold - 27 N * m, throttle los ua ke - 10 N * m.

Throttle Kawm

Hauv txoj kev xav, tom qab hloov lub txim hluav taws xob ntawm Nissan Qashqai yam tsis muaj kev cuam tshuam cov hluav taws xob txuas hluav taws xob, kev kawm throttle yuav tsis xav tau. Tab sis hauv kev xyaum, tej zaum yuav muaj ntau txoj kev xaiv.

Cov hauv qab no yog cov kev ua uas yuav tsum tau ua raws li kev coj ua DZ kev cob qhia hauv ntau hom, thaum koj yuav tsum muaj lub sijhawm nres. Ua ntej koj yuav tsum ua kom sov li kev sib kis, chav tsev fais fab, tua tag nrho cov khoom siv hluav taws xob, muab lub gearbox rau hauv "P" txoj hauj lwm thiab xyuas cov roj teeb theem (tsawg kawg 12,9 V).

Kev ua ntu zus ntawm kev ua thaum qhia tej thaj chaw deb sensing:

• Tom qab ua tiav cov txheej txheem ua ntej, nws yuav tsum tau tua lub cav thiab tos kaum vib nas this;
• Kev sib cuag yog ua tsis tau pib lub cav combustion sab hauv thiab nrog lub accelerator pedal tso rau peb vib nas this;
• Tom qab ntawd, tag nrho lub voj voog ntawm nias yog nqa tawm, ua raws li los ntawm kev tso lub accelerator pedal. Tsis pub dhau tsib vib nas this, yuav tsum tau tsib repetitions;
• Nyob rau hauv lub neej yav tom ntej, muaj ib ncua ntawm xya vib nas this, ces tus accelerator pedal yog nias tag nrho txoj kev thiab tuav. Hauv qhov no, koj yuav tsum tau tos kom lub CHECK ENGINE teeb liab tshwm sim ua ntej nws pib flashing;
• Tom qab lub CHECK ENGINE teeb liab tau muab, lub pedal accelerator yog tuav cia rau peb vib nas this thiab tso tawm;
• Tom ntej no, lub hwj chim unit pib. Tom qab nees nkaum vib nas this, sim ua lub accelerator pedal nrog ib tug ntse nce nyob rau hauv ceev. Nrog rau kev cob qhia kom zoo, qhov nrawm nrawm yuav tsum nyob nruab nrab ntawm 700 thiab 750 rpm.
