Volkswagen BWK cav
Txheem
Tom ntej no 1,4 TSI engine tsim los ntawm VAG engineers tsis tuaj yeem hu ua tiav. Ib tug xov tooj ntawm lub cav kev ua tau zoo tsis tau muab tawm me ntsis qis dua qhov xav tau.
piav qhia
Lub zog hluav taws xob nrog BWK code tau sib sau ua ke ntawm Volkswagen cog txij lub Cuaj Hli 2007. Nws lub hom phiaj tseem ceeb yog txhawm rau txhim kho Tiguan qauv tshiab, uas nws tau teeb tsa kom txog thaum Lub Xya Hli 2018.
Lub saturation ntawm lub cav nrog cov thev naus laus zis siab heev tsis tau tawm mus yam tsis muaj kev saib xyuas tsis yog cov neeg tsav tsheb zoo tib yam, tab sis kuj yog cov kws tshaj lij ntawm ntau qib.
Hmoov tsis zoo, kev ua haujlwm tau nthuav tawm ntau qhov tsis txaus ntseeg, vim tias lub cev muaj zog tsis tau txais kev lees paub dav dav, tshwj xeeb tshaj yog nyob rau hauv Lavxias Federation.
Lub tsev tau dhau los ua qhov xav tau heev ntawm cov cai ntawm kev ua haujlwm, qhov zoo ntawm cov roj thiab cov roj lubricants, cov khoom siv, kev tsim nyog thiab lub sijhawm ntawm nws qhov kev siv. Nws yog qhov tseeb tias cov kev cai no rau peb tus tswv lub tsheb tag nrho rau ntau qhov laj thawj tsis ua tau.
Raws li txoj cai, lub cav yog hloov kho ntawm BMY nrog lub zog ntxiv.
BWK yog nyob rau hauv-kab plaub-lub tog raj kheej petrol unit nrog dual supercharging. Nws ntim yog 1,4 litres, lub hwj chim yog 150 litres. s thiab torque ntawm 240 Nm.
Cam khwb cia hlau cylinder thaiv. Lub tes tsho yog dhuav tawm hauv lub cev ntawm qhov thaiv.
Pistons yog tus qauv, ua los ntawm txhuas, nrog peb lub nplhaib. Ob sab compression, qis roj scraper.
Crankshaft steel, forged, conical zoo. Mounted rau tsib ncej.
Aluminium lub tog raj kheej taub hau. Nyob rau saum npoo yog ib lub txaj nrog ob camshafts. Sab hauv - 16 li qub (DOHC), nruab nrog hydraulic lifters. Lub intake camshaft muaj ib tug camshaft adjuster.
Timing chain tsav. Nws txawv ntawm qhov nws muaj ntau qhov kev tsim teeb meem (saib Tshooj. Weaknesses).
Roj mov system - injector, direct txhaj. Ib qho tshwj xeeb yog xav tau ntawm cov roj av zoo. Tsis zoo roj ua rau detonation, uas rhuav tshem cov pistons. Nyob rau hauv parallel, muaj kev tsim ntawm soot ntawm li qub thiab tshuaj tsuag nozzles. Cov phenomena ntawm poob ntawm compression thiab burnout ntawm lub pistons yog inevitable.
txhaj tshuaj / ignition. Chav tsev yog tswj los ntawm Motronic MED 17 (-J623-) tswj chav tsev nrog kev kuaj tus kheej muaj nuj nqi. Ignition coils yog tus kheej rau txhua lub tog raj kheej.
Supercharging feature. Txog li 2400 rpm nws yog nqa los ntawm Eaton TVS mechanical compressor, ces KKK K03 turbine yuav siv sij hawm dhau. Yog tias xav tau ntau lub zog, lub compressor yuav rov ua haujlwm dua.
Xws li ib tug tandem kiag li tshem tawm cov nyhuv ntawm turbo-lag thiab muab traction zoo nyob rau hauv qab.
Combined lubrication system. Oil VAG Special G 5W-40 (pom zoo thiab specifications: VW 502 00 / 505 00). System peev 3,6 litres.
Cov chaw tsim khoom tau rov txhim kho lub tshuab hluav taws xob sab hauv, tab sis qhov xav tau ntawm kev ua lag luam Lavxias tsis tau ua tiav.

Kev ntseeg tau, tsis muaj zog, kev ruaj ntseg
Kev ntseeg tau
Lub cav Volkswagen BWK, raws li cov chaw tsim khoom lub hom phiaj, yuav tsum dhau los ua cov thev naus laus zis tshaj plaws hauv nws chav kawm. Hmoov tsis, nyob rau hauv kev muaj tiag nws qhia lub feem ntau capricious.
Tshwj xeeb tshaj tawm yog kev vibrations, stretching ntawm lub sij hawm saw, ib tug teeb meem piston pab pawg neeg, nce roj thiab coolant smudges, thiab ib tug xov tooj ntawm lwm yam. Ntawm cov rooj sib tham tshwj xeeb, koj tuaj yeem nyeem ntau cov lus tsis zoo los ntawm cov tswv tsheb txog lub cev muaj zog. Piv txwv li, SeRuS los ntawm Moscow ncaj qha sau: "… CAVA hloov lub mega problematic BWK".
Nyob rau tib lub sijhawm, rau ntau tus, suav tias yog ICE ua rau muaj kev xav zoo. Cov lus teb los ntawm wowo4ka (Lipetsk): "... Kuv ua hauj lwm ntawm ib lub tuam txhab uas lub neej ntawm ob lub tsheb zoo li no ntws ua ntej kuv ob lub qhov muag (peb tab tom tham txog Tiguan). Ntawm ib qho, thaum lub sij hawm muag, muaj ib mais ntawm 212 txhiab, ntawm qhov thib ob 165 txhiab km. Ntawm ob lub tshuab, lub cav tseem muaj sia nyob. Thiab qhov no tsis muaj kev cuam tshuam hauv lub cev muaj zog. Yog li ntawd, lub cev muaj zog tsis yog li ntawd !!!".
Los yog nqe lus ntawm TS136 (Voronezh): "... Kuv tsis nkag siab txhua yam teeb meem muaj peev xwm ua tau nrog lub cav zoo tshaj plaws hauv Europe !!! Tiguan 2008, BWK, khiav 150000 km ntawm nws - tsis muaj dab tsi tawg kiag li. Txhua yam ua haujlwm zoo, Kuv tsis ntxiv roj txhua".
Cov peev txheej thiab cov npoo ntawm kev nyab xeeb yog cov khoom tseem ceeb ntawm kev ntseeg siab ntawm lub cav combustion sab hauv. Tsis muaj lus nug txog qhov no. Cov chaw tsim khoom thov kev kho-dawb khiav ntawm 240 txhiab km. Qhov muaj peev xwm ntawm kev quab yuam lub cav kuj tseem ceeb. Ib qho yooj yim flashing ntawm ECU (theem 1) nce lub zog rau 200 hp. Nrog. Kev sib sib zog nqus tu yuav tso cai rau koj tua 230 hp. Nrog.
Txawm li cas los xij, lub cav tsis tuaj yeem hu ua kev ntseeg siab vim nws "mob" cov tshuaj tiv thaiv rau cov roj av tsis zoo thiab kev sib txawv ntawm cov chaw tsim khoom cov cai ntawm kev saib xyuas.
Lub cev tsis muaj zog
Muaj ntau cov ntsiab lus tsis muaj zog nyob rau hauv lub cav nyob rau hauv kev xav. Ntawm cov no, qhov teeb meem tshaj plaws yog lub sijhawm tsav tsheb.
Kev khiav hauj lwm kev paub tau pom tias cov saw hlau coj teeb meem tshaj plaws. Cov peev txheej tiag tiag ua ntej nws hloov pauv yog 80 txhiab km. Nyob rau tib lub sij hawm, lub crankshaft sprocket thiab lub valve sij hawm regulator yuav tsum tau hloov. Ntxiv mus, qhov no yog ntxiv rau cov khoom siv kho rau cov saw hlau nws tus kheej (tensioner qhov chaw, sprockets, thiab lwm yam).
Kev tsim tsis tiav ntawm hydraulic tensioner (tsis muaj qhov thaiv ntawm qhov kev txav txav ntawm nws lub plunger) tau ua rau lub fact tias nyob rau hauv lub tsis muaj siab nyob rau hauv lub cev muaj zog lubrication system, cov saw nro yog tsis muaj zog. Qhov no ua rau dhia thiab xaus nrog kev cuam tshuam ntawm cov li qub ntawm cov pistons.
Qhov tshwm sim yog ib txwm deplorable - tsis ua hauj lwm ntawm qhov chaw ntawm CPG thiab lub valve mechanism. Txhawm rau kom tsis txhob muaj kev puas tsuaj, nws raug nquahu kom tsis txhob pib lub tsheb los ntawm tus cab thiab tsis txhob tso nws rau hauv lub iav rau lub sijhawm nres tsheb ntev (tshwj xeeb tshaj yog ntawm txoj kab nqes).
Siab xav tau ntawm roj zoo. Qhov yooj yim hauv qhov teeb meem no ua rau detonation, burnout thiab kev puas tsuaj ntawm pistons.
Cov roj tsis zoo ua rau tsim cov coke deposits ntawm lub li qub thiab lub tso pa tawm, roj txais. Qhov no yog qhov pom tseeb tshaj plaws nrog kev nruj kev tsav tsheb.
Nrog lub neej ntev kev pab cuam, lub cav roj hlawv yog pom. Decoking cov roj scraper rings thiab hloov lub valve qia seals ib ntus tshem tawm qhov teeb meem no.
Kev poob qis yog feem ntau pom. Nws tsis yog ib txwm ua tau kom pom qhov ua haujlwm tsis zoo hauv lub sijhawm. Qhov tseeb yog tias tsis muaj qhov pom tseeb ntawm cov kua dej, thiab qee qhov me me los ntawm cov dej ntws tawm muaj sijhawm rau evaporate. Thiab tsuas yog tom qab, nyob rau hauv lub wake ntawm lub teev tsim, nws muaj peev xwm los txiav txim qhov tseeb qhov chaw ntawm lub xau. Feem ntau qhov teeb meem yuav tsum tau saib rau hauv lub intercooler.
Feem ntau lub cav troit thaum pib txias, lub suab zoo ib yam li kev ua haujlwm ntawm lub cav diesel. Tsis kaj siab, tab sis tsis txaus ntshai. Qhov no yog hom kev ua haujlwm ntawm chav tsev. Tom qab sov so txhua yam rov qab mus rau qhov qub.
Lub turbine tsav tsis txhim khu kev qha. Kev tu kom huv tshem tawm qhov teeb meem.
Muaj lwm yam malfunctions ntawm lub cav, tab sis lawv tsis yog ib tug loj xwm.
Txij nkawm zoo
Muab lub siab manufacturability ntawm lub cev muaj zog, nws yog ib qho yooj yim mus xaus hais tias nws yog tswj. Kho, tab sis nyob rau hauv ib lub tsheb pab. Tsis tas li ntawd, koj yuav tsum tau npaj rau tus nqi siab ntawm kev kho dua tshiab.
Lub cam khwb cia-hlau thaiv ntawm lub tog raj kheej tso cai ua tiav kev kho dua tshiab. Nrhiav qhov chaw tsis muaj teeb meem.
Cov neeg uas nqa tawm lub restoration ntawm lub internal combustion engine yog qhia kom yuav ib daim ntawv cog lus cav. Hais txog tus nqi, qhov kev xaiv no yuav pheej yig dua. Tus nqi ntawm ib daim ntawv cog lus cav nyob rau hauv thaj tsam ntawm 80-120 txhiab rubles.
Koj tuaj yeem pom cov txheej txheem kho los ntawm kev saib cov yees duab:
Lub cav Volkswagen BWK, rau tag nrho nws cov txiaj ntsig, tsis yog nrov ntawm cov tswv tsheb Lavxias, nws suav tias yog capricious thiab tsis txhim khu kev qha.
