VAZ-2109 tej zaum yog lub tsheb nto moo tshaj plaws hauv tebchaws Russia. Lub tsheb no tau tsim tawm txij li hnub ntawm USSR. Nws yog thawj lub tsheb uas lub torque tau xa mus rau pem hauv ntej es tsis yog lub log tsheb. Lub tsheb sib txawv heev hauv kev tsim los ntawm ib txwm "classics". Tab sis yog VAZ-2109 tso pa system txawv li ntawd? Cov cuab yeej, lub hom phiaj thiab cov yam ntxwv ntawm lub kaw lus yuav raug piav qhia tom qab hauv kab lus.

Koj xav tau dab tsi?

Lub luag haujlwm tseem ceeb ntawm txhua qhov tso pa tawm yog tawm cov pa roj tawm ntawm lub combustion chamber ntawm lub cav. Nyob rau hauv cov ntaub ntawv no, qhov kub ntawm cov gases txo nyob rau hauv txoj kev mus rau sab nraud ib puag ncig. Lawv lub suab kuj txo qis, ua tsaug rau cov ntsiab lus ntxiv (peb yuav xav txog cov cuab yeej ntawm VAZ-2109 tso tawm hauv qab). Tus tsim ntawm qhov system no tsis nyuaj, tab sis nws ua tsis tau yam tsis muaj nws.

Device

Nyob rau hauv tag nrho, qhov system no suav nrog ob peb yam. Nov yog:

• Txaus siab heev. Nov yog thawj qhov nthuav dav heevlos ntawm qhov uas cov gases dhau tom qab combustion. Tus sau tau nrov npe hu ua kab laug sab rau nws cov yam ntxwv zoo. Cov khoom no yog muab rau txhua ntawm plaub lub tog raj kheej ntawm lub cav combustion sab hauv. Tsis tas li ntawd, tag nrho cov kav dej no tau muab tso rau hauv ob, thiab tom qab ntawd mus rau hauv ib qho. Kuj tseem muaj cov kis las kis las nrog 4-2-1 tso tawm qauv. Lawv raug ntsia kom ntxiv zog. Raws li kev xyaum qhia, cov pa roj tau txav mus los ntawm txoj kev, txawm li cas los xij, tus neeg tsav tsheb tseem yuav tsis xav tias muaj zog ntxiv.
• Lub pas dej. Nws txuas mus rau lub collector. Hauv cov yeeb nkab no muaj ib qho kev sojntsuam tshwj xeeb. Qhov no yog ib qho oxygen sensor, los yog lambda sojntsuam. Yog hais tias peb tham txog lub VAZ-2109 pa system (carburetor), tsis muaj xws li sensor nyob rau hauv lub system. Tab sis ntawm nws pib injectors, yuav tsum tau ib tug lambda sojntsuam. Qhov teeb meem me me nrog nws tuaj yeem nrog lub teeb "Check Engine" ntawm lub ntsuas ntsuas. Qhov tseeb, cov yeeb nkab tau txais muaj cov cuab yeej yooj yim tshaj plaws. Tsis muaj suab-reflector baffles lossis tshwj xeeb fillers. Qhov no yog cov yeeb nkab hollow zoo tib yam, uas tuaj yeem ua tau raws li ib qho sensor.
• Catalyst. Raws li nyob rau hauv cov ntaub ntawv dhau los, lub caij no tsuas yog muaj nyob rau hauv kev txhaj tshuaj versions. Tsis muaj catalyst ntawm carburetor. Cov khoom no yog dab tsi? Nws lub luag haujlwm tseem ceeb yog txo qhov concentration ntawm cov khoom tsis zoo hauv cov pa tawm. Dhau los ntawm cov kab mob catalyst, cov hlau tsis zoo hloov mus rau cov oxides tsis muaj teeb meem. Ua tsaug rau kev siv cov khoom no, lub tshuab pib ua raws li ib puag ncig tus qauv Euro-2 thiab siab dua. Lub catalytic converter yog cov khoom kim tshaj plaws nyob rau hauv lub tso pa tawm. Vaz-2109 (injector). Yog li ntawd, thaum nws malfunctions, ntau nruab nplaim ntes los yog tsuas yog khob tawm cov tub ntxhais thiab vuam cov phab ntsa, tawm hauv catalyst khoob.
• Resonator. Cov khoom no muaj nyob rau hauv ob qho tib si carburetor thiab txhaj tshuaj. Lub resonator yog ntsia tom qab lub catalyst. Nws txoj hauj lwm yog dab tsi? Lub resonator pab nqus lub suab nrov los ntawm cov pa pa. Ua tsaug rau cov khoom no, lub suab ntawm cov pa roj yuav tsawg dua. Lub resonator yog yooj yim. Qhov no yog ib rooj plaub hlau, nyob rau hauv uas muaj ib tug perforated yeeb nkab. Tsis tas li ntawd, tej zaum yuav muaj kev faib tawm sab hauv.
• Main muffler. Lub resonator tuaj yeem raug hu ua tus pabcuam muffler, tab sis nws yog qhov kawg muffler, nyob hauv qab lub nraub qaum, uas absorbs lub suab nrov zog. Nws nkag mus rau lub resonator thiab absorbs txog li 90 feem pua ntawm lub suab. Cov ntsiab lus no yog qhov nyuaj me ntsis. Perforated hlab kuj tau coj los ua lub hauv paus ntawm no, tab sis muaj ob peb ntawm lawv, nrog rau cov koob yees duab. Feem ntau cov no yog peb lossis plaub lub raj thiab ob lub koob yees duab. Dhau los ntawm txoj kev tshawb no, cov pa roj poob lawv lub zog thiab tawm mus ntsiag to.

Faults

Vim nws txoj kev tsim qauv yooj yim, qhov system no txhim khu kev qha thiab tsis tshua xav tau kev saib xyuas. Tab sis tsis muaj dab tsi nyob mus ib txhis, yog li xyoo dhau los, cov muffler thiab lwm yam khoom kub hnyiab tawm. Feem ntau, nws yog lub muffler uas ua tsis tau, raws li nws yuav siv rau tag nrho cov tshuab. Nws tuaj yeem hlawv ob sab nraud thiab sab hauv. Nyob rau hauv rooj plaub tom kawg, koj tuaj yeem txiav txim siab qhov tawg ntawm lub suab nrov ntawm cov pa tawm. Caij nrog xws li Silencer tsis txaus ntshai, tab sis tsis xis nyob heev. Ua ntej, lub suab nrov rwb thaiv tsev raug kev txom nyem, thiab qhov thib ob, cov pa roj tuaj yeem tawg mus rau hauv chav tsev. Yog li ntawd, nws yog qhov zoo dua los hloov lub caij no tam sim, muab tias nws raug nqi ib npib.

Kev kho dua tshiab

Qee tus tswv siv los kho cov muffler. Tab sis nws yuav tsum tau hais tias cov xwm txheej zoo li no, yog tias tsis muaj txiaj ntsig, ces tsawg kawg ib ntus. Qhov tseeb yog tias cov pa roj tuaj yeem tawg tsis tsuas yog tawm ntawm lub muffler, tab sis kuj sab hauv. Ntawd yog, tom qab txhim kho lub thaj, lub suab tawm yuav tsis hloov. Tus nqi ntawm ib tug tshiab muffler rau "cua" yog tam sim no txog ib txhiab rubles. Thiab nws yuav kav ntev npaum li qhov qub kho dua.

Yuav hloov li cas?

Raws li cov saum toj no, peb tuaj yeem xaus tias qhov kev kho cov muffler zoo tshaj plaws yog hloov nws. Cov lus no tseem muaj feem xyuam rau lwm qhov chaw ntawm VAZ-2109 tso pa tawm. Lub muffler hloov yog tias muaj qhov tshuaj ntsuam xyuas, lub nplhaib ntiv nplhaib rau 13 thiab lub taub hau kawg nrog tib qhov loj. Txhua qhov kev ua tau ua ib kauj ruam:

• Lub tsheb tau tsav mus rau hauv qhov tshuaj ntsuam thiab muab tso rau hauv iav.
• Lub ntsiab muffler yog txiav tawm ntawm lub resonator. Ua li no, koj yuav tsum nrhiav ib lub clamp. Cov txiv ntoo kho yog rub nrog spanner ciaj ntswj (kom tiv thaiv scrolling). Lub sij hawm no, lub bolt yog unscrewed nrog ib tug ratchet.
• Tom qab cov fasteners raug tshem tawm thiab cov ntsiab lus ntawm cov pa tawm raug txiav tawm. Lub clamp yog reusable, yog li peb yuav muab nws rov qab.
• Lub hauv ntej ntawm muffler yog ua tib zoo tshem tawm ntawm cov roj hmab "lub hauv ncoo",los ntawm qhov uas ib feem yog txuas rau lub cev. Tom qab ntawd tib txoj haujlwm ua tiav nrog rau pem hauv ntej "hauv ncoo".
• Yog hais tias lub muffler daig rau lub raj resonator, nws tuaj yeem tig rov ua dua thiab rov ua dua. Qhov no ua rau nws yooj yim dua los tshem cov muffler.
• Ib lub caij tshiab tau teeb tsa hauv qhov kev txiav txim rov qab.

Thov nco ntsoov tias cov ntaub qhwv roj hmab tuaj yeem tawg. Nws yog qhov zoo dua los yuav cov khoom seem. Nyob rau hauv "cua" lawv yog heev flimsy. Nws raug nquahu kom muab cov hauv ncoo ua los ntawm cov khoom siv ruaj khov (piv txwv li, polyurethane). Qhov no yuav tsis cuam tshuam rau kev nplij siab (yuav tsis muaj kev vibrations ntxiv), tab sis cov peev txheej tsawg kawg yog ob zaug loj.

Hloov lub resonator

Yuav ua li cas, peb xav tau cov cuab yeej yooj yim (qhib kawg wrenches thiab taub hau), nrog rau lub qhov pom. Koj tuaj yeem pib kho lub VAZ-2109 tso pa tawm tsuas yog tom qab paub tseeb tias nws tau txias. Yog li, peb yuav tsum tau txiav lub resonator nrog lub muffler ntawm ib sab thiab nrog cov catalyst ntawm lwm qhov. Koj xav tau ib tug ciaj ntswj rau unscrew ob peb bolts. Tom qab ntawd peb tsa lub resonator thiab disconnect nws los ntawm cov roj hmab pads. Yog hais tias lub resonator tsis qiv nws tus kheej, koj yuav tsum siv lub tiaj tus ntsia hlau. Nrog nws, peb tuaj yeem maj mam rub tawm cov roj hmab ncua kev kawm. Tom qab ntawd txhua yam yog yooj yim - peb muab ib feem tawm thiab muab ib qho tshiab rau hauv nws qhov chaw. Kev sib dhos yog ua raws li kev txiav txim rov qab.

Catalyst

Hloov cov catalyst ntawm "cuaj" yog qhov ua haujlwm tsis tsim nyog vim yog tus nqi. Nws yog qhov pheej yig dua los hloov cov khoom no nrog cov nplaim taws. Exhaust systemVAZ-2109 (injector, 8 li qub) yuav tsis hloov nws cov yam ntxwv, thaum lub tso pa yuav tseem nyob ntsiag to. Qhov tsuas yog qhov uas yuav hloov pauv yog toxicity ntawm gases. Exhaust yuav ntau caustic. Yog li, dab tsi xav tau rau qhov no? Lub catalyst nws tus kheej raug tshem tawm ua ntej. Txhawm rau ua qhov no, koj xav tau ib txheej ntawm cov yuam sij thiab lub qhov pom. Tom qab unscrewing tag nrho cov fasteners, ib feem tau tawm. Nyob rau hauv nws qhov chaw yog ib tug nplaim ntes. Cov nplaim hluav taws npaj ua tiav yog qhov zoo tagnrho rau qhov loj. Muaj ntau yam no muag hauv khw.

Tub

Cov neeg uas xav hloov lub suab ntawm cov pa tawm mus rau ib qho kev ua kis las tuaj yeem nruab Stinger ncaj nraim los ntawm muffler. Lub tshuab tso pa ntawm VAZ-2109 kuj tseem ua tiav los ntawm kev txhim kho Stinger kab laug sab.

Vim li ntawd, cov pa roj yuav tawm hauv chav combustion dawb. Tab sis koj yuav tsum nkag siab tias lub suab nrov yuav nce ntau zaus. Txij li thaum tsis muaj cov labyrinths nyob rau hauv ib qho ncaj-los ntawm muffler, tag nrho cov gases ncaj qha mus rau qhov chaw.

Lub tsheb yuav ua suab nrov, tab sis tsis tas yuav tham txog kev nce lub zog loj. Ib qho kev daws teeb meem zoo dua yog txhawm rau txhim kho xws li Silencer tom qab kho lub cev muaj zog. Koj tuaj yeem pib los ntawm kev txhim kho lub taub hau 16-valve, tom qab ntawd hloov cov khoom noj, mount lub turbine, thiab lwm yam. Tsis muaj teeb meem dab tsi hauv kev tso dej ntws mus rau ntawm lub cav VAZ yooj yim. Tsis tu ncua tso pa system thiab yog li tiv nrog cov pa tawm los ntawm ib tug yooj yim ib txwm aspirated engine. Nyob rau hauv rooj plaub ntawm kev txhim kho lub turbine ntawm "cua" xws liKev kho dua tshiab tsuas yog tsim nyog.

Zoo kawg

Yog li, peb tau saib yuav ua li cas lub tshuab pa ua haujlwm ntawm VAZ-2109. Raws li koj tuaj yeem pom, tus qauv tsim ntawm qhov system no yog qhov qub heev, thiab yog li ntawd txhua qhov kev kho yuav ua tau los ntawm tes.
