Diagnostics ntawm common rail diesel injectors

Niaj hnub nimno diesel xyaw muaj zog, kev lag luam thiab ruaj khov. Tab sis, txawm tias tag nrho lawv qhov zoo, lawv muaj qhov tsis muaj zog: cov roj system. Feem ntau cov diesels siv Common Rail system. Lawv yog dab tsi? Cov tshuaj txhaj tshuaj li cas? Lawv fixable li cas? Ntxiv rau hauv tsab xov xwm, peb yuav tham txog qhov ua haujlwm tsis zoo ntawm cov tsheb ciav hlau diesel injectors thiab lawv qhov kev kuaj mob.

Hom ntawm Common Rail systems

Muaj ntau ntau hom Common Rail systems, tab sis raws li txoj cai lawv poob rau hauv ob pawg:

• electromagnetic,
• piezoelectric tshuaj.

Cov tshuab no muaj nyob rau hauv plaub lub npe:

1. khoob
2. Continental (yav tas los Siemens),
3. Delphi,
4. ntom.

Tus thawj coj ua lag luam yog Bosch, uas sawv cev rau feem ntau ntawm cov tshuaj tua hluav taws xob. Raws li hom no, ob qho tib si electromagnetic thiab piezoelectric diesel nozzles raug tsim. Delphi kuj tseem tsim ob hom kev txhaj tshuaj. Thiab Denso thiab Continental tsuas yog ua piezoelectrics.

Nws tsis tuaj yeem hais tias hom twg ntawm Common Rail diesel injectors yog qhov zoo dua, vim tias cov tshuab sib txawv muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Bosch injectors yog qhov yooj yim tshaj los kho: tsis tsuas yog lawv muaj cov qauv yooj yim tshaj plaws ntawm txhua qhov, lawv kuj yog qhov feem ntau, yog li nrhiav kev hloov pauv tsis yog teeb meem.

Delphi diesel injectors yog qhov nyuaj dua: lawv muaj ntau txoj kev tswj hwm. Vim li no, cov tshuaj txhaj tshuaj tau hloov pauv mus rau qhov zoo ntawm cov diesel, yog li lawv tsis tau ua haujlwm nyob rau hauv peb lub teb chaws ntev. Thaum kho cov tshuaj tua hluav taws xob ntawm lwm hom, feem ntau muaj teeb meem nrog kev nrhiav cov khoom seem.

Kev ruaj ntseg ntawm cov twj siv hluav taws xob diesel injectors

Yog hais tias, raws li qhov tshwm sim ntawm kev kuaj mob ntawm Common Rail diesel injectors, qhov tsis zoo tau raug txheeb xyuas, cov lus nug tshwm sim seb puas muaj peev xwm kho tau lossis yuav tsum tau hloov tag nrho. Feem ntau ntawm cov tswv zoo siab ntawm Common Rail roj system nrog Bosch injectors. Vim lawv cov qauv tsim yooj yim thiab siv dav, lawv yog qhov yooj yim tshaj plaws los tswj thiab pheej yig dua los tsim kho.

Txawm hais tias qhov teeb meem cuam tshuam nrog kev ua haujlwm tsis zoo ntawm cov tshuaj txhaj tshuaj, nws yog ib qho tsim nyog los kho cov roj hluav taws xob hauv qhov chaw tshwj xeeb, vim tias tus nqi ntawm cov khoom seem yog qhov zoo thiab tsis muaj qhov cuam tshuam rau nws. Rau kev kuaj mob ntawm cov twj tso kua mis diesel, lawv kho thiab hloov, thov hu rau https://dizelbox.ru/remont-dizelnyh-forsunok.

Delphi solenoid-hom diesel injectors kuj suav hais tias kho tau, tab sis lawv kim dua los tsim dua Bosch. Qhov no yog vim lub fact tias tom qab hloov lub ntsis (thiab qhov no yog tsim nyog), koj yuav tsum tau encode, txwv tsis pub lub cev muaj zog yuav ua hauj lwm unstably.

Denso electromagnetic diesel injectors yog xyaum unrepairable. Ua ntej ntawm tag nrho cov, lub nozzles ntawm lub hom no yog cov feem ntau txhim khu kev qha thiab ruaj. Qhov thib ob, nws yog qhov nyuaj heev los nrhiav cov khoom seem rau lawv - feem ntau ntawm cov xwm txheej, nws yog qhov nrawm dua, yooj yim dua, thiab qee zaum pheej yig dua rau nruab cov tshiab.

Bosch thiab Delf piezoelectric injectors tsis tuaj yeem kho. Yog hais tias thaum lub sij hawm kuaj mob ntawm Common Rail diesel injectors lawv malfunction tau tshwm sim, ces cov khoom yeej ib txwm hloov mus rau tshiab.

Raws li rau Continental (yav tas los Siemens) diesel injectors, lawv tsis tau kho kom txog thaum tsis ntev los no. Twb tau ntawm kev muag khoom koj tuaj yeem nrhiav cov lus qhia txhaj tshuaj rau kev hloov pauv, thiab ntawm cov kab sib txawv. Yog li, koj tuaj yeem xaiv qhov kev xaiv zoo rau txhua qhov kev txhaj tshuaj thiab rov ua haujlwm ntawm tus nqi tsawg (piv rau kev yuav ib qho tshiab.

Thaum kuaj pom Common Rail Diesel Injectors

Raws li cov chaw tsim khoom, lub neej kev pab cuam ntawm Common Rail diesel injectors yog 100-150 txhiab kilometers. Hauv kev xyaum, feem ntau cov nozzles tuaj yeem tiv taus txog li 150-200 txhiab kilometers. Xav txog tus nqi ntawm cov khoom thiab kev ua haujlwm thaum hloov pauv, cov kws tshaj lij tsis pom zoo kom hloov cov twj tso kua mis Common Rail injectors kom txog thaum muaj teeb meem pib nrog lawv.

Nws yog ib qho tsim nyog los kuaj xyuas Common Rail diesel injectors yog tias cov pa tso pa dhau lawm, kev siv roj tau nce ntxiv. Ob lub teeb liab no yog qhov laj thawj tseem ceeb rau kev hu rau Common Rail Diesel Injector Diagnostic Assistant.

Ua rau malfunction ntawm common rail diesel injectors

Cia peb xav txog cov ntsiab lus tseem ceeb ntawm kev puas tsuaj hauv cov roj av ntawm cov cav diesel:

• Thaiv.

Yog tias pom cov tshuaj tiv thaiv clogged thaum kuaj xyuas cov tshuab hluav taws xob sib txuas hluav taws xob, tus tswv tuaj yeem ua pa, vim tias qhov ua haujlwm tsis zoo no kuj yooj yim thiab pheej yig los kho.

Yuav ua li cas: Flush lub clogged nozzle koob. Qhov no tuaj yeem ua tiav nrog lub tshuab ntxhua khaub ncaws ultrasonic lossis los ntawm tes siv cov scrapers tshwj xeeb thiab txhuam.

• Lub tshuab ntxhua khaub ncaws hnav

Nruab nrab ntawm lub atomizer thiab lub caij nplooj ntoos hlav nyob rau hauv lub Common Rail diesel injector yog lub tshuab ntxhua khaub ncaws, uas nws thiaj li deforms thiab poob nws rigidity.

Yuav ua li cas: Hloov lub tshuab ntxhua khaub ncaws.

• Corrosion hnyav los yog hnav.

Corrosion los yog cov cim qhia ntawm kev hnav tseem ceeb, txheeb xyuas thaum kuaj xyuas ntawm cov twj siv hluav taws xob diesel, tuaj yeem ua rau lub cev puas tsuaj. Txij li cov vaj tse tsis tuaj yeem hloov tau nyias, yuav tsum tau muab ib feem tshiab.

Yuav ua li cas: Nruab ib lub tshuab hluav taws xob tshiab.

• Qhov chaw txhaj tshuaj raug kaw.

Kev ua haujlwm kom raug ntawm lub tshuab hluav taws xob diesel yog txiav txim siab los ntawm ntau qhov tsis sib xws: qhib siab, lub taub hau injector, rab koob txav, thiab lwm yam. Rau qhov no, cov injectors txuas nrog rau kev teeb tsa tshwj xeeb uas simulates kev ua haujlwm ntawm lub cav. Nyob rau hauv cov ntaub ntawv no, cov roj yog txau mus rau ib daim ntawv, tsim ib qho chaw ntawm ib tug tej yam zoo li.
