Cov pa luam yeeb dawb los ntawm cov yeeb nkab tso tawm: peb nkag siab cov laj thawj

Yog tias koj lub tsheb lub cav thiab tag nrho cov tshuab uas nyob ib sab ntawm nws ua haujlwm zoo, ces qhov tso pa tawm tsis muaj dab tsi ntau tshaj li cov dej vapor, nitrogen thiab carbon dioxide. Thaum lub sijhawm ua haujlwm ntawm lub chaw pabcuam, cov kwj ntawm cov roj yuav luag tsis muaj xim ntws los ntawm cov yeeb nkab. Lub catalyst kuj koom nrog hauv kev ua kom huv, uas tshem tawm ntau cov pa roj ntawm lub qhov hluav taws xob ntawm cov pa tawm manifold.

Tab sis qee zaum koj tuaj yeem pom tias cov pa luam yeeb dawb tawm ntawm lub muffler. Tab sis koj tsis tas yuav ntshai tam sim ntawd, tab sis ua ntej ntawm tag nrho cov, koj yuav tsum coj mus rau hauv tus account ntau yam uas yuav tsis qhia ib tug malfunction nyob rau hauv lub tsheb.

Thaum twg cov pa luam yeeb dawb suav tias yog ib txwm?

Cov pa luam yeeb tuab tuab thaum lub cav tsis sov yog qhov tshwm sim ib txwm muaj, lossis qhov no, nws tsis yog haus luam yeeb, tab sis cov pa taws los ntawm cov dej ntws los ntawm cov pa tawm, condensing ntawm cov kav dej txias. Raws li ntau tus neeg paub, condensate cov ntaub ntawv vim qhov sib txawv ntawm qhov kub thiab txias, thiab cov pa cua sov thiab qhov chaw txias ntawm cov kav hlau ntawm cov pa tawm yog qhov chaw zoo rau kev tsim cov condensate. Yog li ntawd, cov nyhuv no yuav tsum ploj mus thaum lub cav yog tag nrho warmed. Tsis tas li ntawd, cov pa luam yeeb tuab tuab yuav raug tso tawm txawm tias nyob rau ntawm lub cav sov ntawm qhov kub thiab txias. Pib los ntawm Frost ntawm -10 degrees Celsius, qhov kev siv ntawm cov nplua nuj dawb paug gases yuav nce nrog txhua qhov txo qis hauv huab cua kub.

Thaum twg cov pa luam yeeb dawb los ntawm cov yeeb nkab tso tawm qhia tias muaj kev puas tsuaj?

Cov pa luam yeeb dawb yog ib qho cim qhia ntawm cov av noo siab hauv qhov tso pa tawm. Tom qab lub cav sov so, chav thiab condensate ploj. Yog tias cov pa luam yeeb dawb tseem tawm hauv cov pa tawm, qhov no yog ib qho cim ntawm lub cav ua haujlwm tsis zoo.

Ua rau thiab cov tsos mob ntawm malfunction

Antifreeze leak. Yog hais tias lub cav twb sov lawm, tab sis cov pa luam yeeb dawb tseem tawm hauv cov pa tawm, cov dej xau sab hauv tuaj yeem tsim. Yog tias muaj ntxhiab tsw qab ntxiag hauv huab cua, qhov no yog qhov pom tseeb tshaj plaws ntawm cov teeb meem uas tau hais tseg.

Yog vim li cas rau qhov no nyob rau hauv ib tug tawg nyob rau hauv lub tog raj kheej taub hau los yog txawm nyob rau hauv lub cav thaiv. Txawm hais tias nws yog me me, antifreeze yooj yim xau tawm thiab paug cov roj hauv lub cav. Qhov no ua rau cov pa hluav taws xob tig dawb, vim tias qhov sib xyaw ua ke ntawm cov dej txias thiab cov roj cav ua rau nws zoo li milky. Txawm tias me me ntawm cov coolant nkag mus rau hauv combustion chamber pab tsim cov pa luam yeeb dawb.

Cov dej xau hauv lub nplhaib piston lossis valve foob. Lwm qhov ua rau cov pa luam yeeb dawb yog xau valve seals lossis piston rings, uas ua rau cov roj nkag mus rau hauv lub combustion chamber, uas nws sib tov nrog roj thiab hlawv. Raws li qhov tshwm sim, cov pa luam yeeb dawb los yog xiav me ntsis tawm ntawm lub qhov tso pa tawm.

Faulty injector. Yog hais tias lub injector yog daig qhib los yog yog hais tias lub O-ring yog to, roj ntau dhau yuav nkag mus rau hauv lub combustion chamber. Cov roj ntau dhau no tsis tuaj yeem hlawv kom zoo hauv lub cav thiab hloov mus rau qhov tso pa tawm hauv cov pa luam yeeb dawb lossis grey.

Lub sij hawm tsis raug ntawm lub twj tso kua mis roj (rau cov tsheb nrog lub cav diesel). Lub cav diesel yuav tsum tau synchronization ntawm lub sij hawm thiab roj siab ntawm cov roj twj tso kua mis. Yog tias lub sijhawm tsis raug, lub cav yuav khiav ntawm kev kub ceev, thiab qhov no yuav ua rau cov roj tsis hlawv tag nrho, tab sis yuav tsum tau tawm ntawm cov yeeb nkab tso pa tawm los ntawm cov pa taws dawb lossis grey.

Yuav ua li cas yog cov pa luam yeeb dawb tawm ntawm cov yeeb nkab?

Yog tias cov pa luam yeeb dawb tseem tawm hauv cov yeeb nkab tawm txawm tias tom qab ua kom sov, ces yuav tsum tau kuaj xyuas.

1. Thawj qhov uas yuav tsum tau xyuas nrog cov pa luam yeeb dawb tas li yog tshem tawm cov dipstick thiab xyuas kom meej tias tsis yog cov roj theem lossis nws qhov kev hloov pauv (cov xim mis nyuj, emulsion), vim tias qhov tshwm sim ntawm cov dej nkag mus rau cov roj yog qhov phem tshaj rau lub cav. Tsis tas li ntawd, cov pa tawm yuav tsis tawm cov pa luam yeeb dawb, tab sis nrog lub ntsej muag xiav. Cov yam ntxwv no cov roj pa luam yeeb los ntawm cov yeeb nkab tso tawm nyob tom qab lub tsheb ntev ntev hauv daim ntawv pos huab. Thiab los ntawm kev qhib lub hau ntawm lub tank nthuav dav, koj tuaj yeem pom cov yeeb yaj kiab ntawm cov roj ntawm qhov chaw ntawm lub coolant thiab hnov ​​​​qhov tsis hnov ​​​​tsw ntawm cov pa roj. Los ntawm cov xim ntawm soot ntawm lub txim taws lossis nws qhov tsis tuaj, koj tuaj yeem paub txog qee qhov teeb meem. Yog li, yog tias nws zoo li tshiab lossis ntub tag, qhov no qhia tau tias dej tau nkag mus rau hauv lub tog raj kheej.

2. Ib daim ntaub dawb kuj tseem yuav pab txheeb xyuas lub hauv paus chiv keeb ntawm cov pa luam yeeb. Nrog lub cav khiav, koj yuav tsum tau coj nws mus rau qhov tso pa thiab tuav nws li ob peb feeb. Yog tias cov pa luam yeeb yog vim cov dej noo zoo tib yam, ces nws yuav huv si, yog tias cov roj nkag mus rau hauv lub tog raj kheej, cov yam ntxwv greasy me ntsis yuav nyob twj ywm, thiab yog tias antifreeze sees tawm, ces cov me ntsis yuav xiav los yog daj, thiab nrog ib tug qaub tsw. Thaum cov cim qhia tsis ncaj qha qhia qhov ua rau pom cov pa luam yeeb dawb los ntawm cov pa tawm, ces nws yuav tsum tau qhib lub cav thiab nrhiav kom pom qhov tsis xws luag. Cov kua dej tuaj yeem nkag mus rau hauv lub tog raj kheej los ntawm kev puas tsuaj los yog tawg hauv qhov thaiv thiab lub taub hau.

3. Thaum nrhiav cov kab nrib pleb, xyuam xim tshwj xeeb rau tag nrho saum npoo ntawm lub tog raj kheej lub taub hau thiab thaiv nws tus kheej, nrog rau sab hauv ntawm lub tog raj kheej thiab qhov chaw nkag thiab qhov tso tawm valve. Nrog lub microcrack, nws yuav tsis yooj yim los nrhiav qhov xau, koj yuav xav tau kev sim siab tshwj xeeb. Tab sis yog tias qhov tawg yog qhov tseem ceeb, tom qab ntawd txuas ntxiv kev ua haujlwm ntawm lub tsheb no tuaj yeem ua rau dej rauj, vim tias cov kua dej tuaj yeem khaws cia rau hauv qhov chaw saum lub piston.

4. Tej zaum nws yuav tshwm sim tias koj tsis hnov ​​​​tsw pa hauv lub tshuab hluav taws xob, lub siab tsis nce siab hauv nws, tab sis muaj cov pa luam yeeb dawb, emulsion, es tsis muaj roj, thiab qhov poob ntawm nws qib yog pom tau. Qhov no qhia tau hais tias cov dej nkag mus rau hauv lub tog raj kheej los ntawm kev nkag mus. Txhawm rau txiav txim siab qhov laj thawj ntawm cov dej nkag mus rau hauv lub tog raj kheej, nws yog qhov txaus los tshuaj xyuas cov khoom siv manifold yam tsis tau tshem tawm lub tog raj kheej taub hau.

Thov nco ntsoov tias txhua yam tsis xws luag uas ua rau tsim cov pa luam yeeb dawb xav tau ntau dua li tsuas yog tshem tawm qhov ua rau ncaj qha. Cov teeb meem no yog tshwm sim los ntawm overheating ntawm lub cav, thiab yog li ntawd nws yog tsim nyog los xyuas thiab kho cov kev puas tsuaj nyob rau hauv lub txias system. Yog tias koj tsis muaj kev paub dhau los, nws yog qhov zoo dua tsis txhob sim kho qee yam ntawm koj tus kheej. Hu rau tus kws tshaj lij tshwj xeeb kom koj tsis tas yuav them ob zaug thiab kho cov teeb meem loj dua nrog lub cav tom qab. Cov neeg ua haujlwm ntawm qhov chaw pabcuam yuav kuaj xyuas koj tam sim, txheeb xyuas cov teebmeem thiab kho lawv.

Cov pa luam yeeb dawb los ntawm cov yeeb nkab tso tawm tsis tas yuav ua rau muaj teeb meem loj, tab sis nws tsis raug mob los xyuas dua thiab xyuas kom meej tias txhua yam nyob rau hauv kev txiav txim nrog lub tshuab. Yog li ntawd, nws yuav tsis yog superfluous mus cuag ib tug zoo chaw nres tsheb, qhov twg craftsmen muaj peev xwm sai thiab raug kuaj xyuas tag nrho cov nodes. Tsis tas li ntawd, raws li kev xyaum qhia, tus kws tshaj lij craftsman nrog tag nrho cov cuab yeej tsim nyog thiab cov cuab yeej tsim nyog yuav daws tau qhov teeb meem no ntau zaus sai dua li ib tus neeg hauv cov chaw nres tsheb yooj yim.
