Diagnostics a common njanji dizilo jekeseni

Ma injini a dizilo amakono ndi amphamvu, azachuma komanso olimba. Koma, mosasamala kanthu za ubwino wawo wonse, ali ndi mfundo yofooka: dongosolo la mafuta. Ma dizilo ambiri amagwiritsa ntchito Common Rail system. Ndiziyani? Kodi jekeseni amazindikiridwa bwanji? Kodi zingatheke bwanji? Komanso m'nkhaniyi, tikambirana za zovuta zazikulu za majekeseni a dizilo wamba ndi matenda awo.

Mitundu ya Common Rail systems

Pali mitundu ingapo ya machitidwe a Common Rail, koma kwenikweni amagwera m'magulu awiri:

• electromagnetic,
• piezoelectric.

Makina otere amapezeka pansi pa mayina anayi amtundu:

1. opanda kanthu
2. Continental (kale Nokia),
3. Delphi,
4. Zokhuthala.

Mtsogoleri wamsika ndi Bosch, yemwe amayimira majekeseni ambiri a dizilo. Pansi pa mtundu uwu, onse ma electromagnetic ndi piezoelectric diesel nozzles amapangidwa. Delphi imapanganso mitundu iwiri ya jekeseni. Ndipo Denso ndi Continental amangopanga ma piezoelectrics.

Sizingatheke kunena kuti majekeseni a dizilo a Common Rail ndi ati, chifukwa makina osiyanasiyana ali ndi zabwino ndi zovuta zawo. Majekeseni a Bosch ndi osavuta kukonza: sikuti ali ndi mapangidwe osavuta kuposa onse, amakhalanso ofala kwambiri, kotero kupeza m'malo si vuto.

Majekeseni a dizilo a Delphi ndi ovuta kwambiri: ali ndi machitidwe ovuta kwambiri olamulira. Chifukwa cha izi, majekeseni adakhala okhudzidwa kwambiri ndi dizilo, kotero kuti sanagwire ntchito m'dziko lathu kwa nthawi yayitali. Pokonza majekeseni a dizilo amtundu wina, nthawi zambiri pamakhala vuto lopeza zida zosinthira.

Kusungika kwa ma jekeseni a dizilo wamba njanji

Ngati, chifukwa cha matenda a jekeseni wa dizilo wa Common Rail, zofooka zimadziwika, funso limakhala ngati kukonzanso kuli kotheka kapena kusintha kwathunthu kudzafunika. Ambiri mwa eni okondwa a Common Rail fuel system yokhala ndi majekeseni a Bosch. Chifukwa cha kuphweka kwawo komanso kugwiritsidwa ntchito kofala, ndizosavuta kuzisamalira komanso zotsika mtengo kuzimanganso.

Kaya vuto limakhala lotani chifukwa cha kulephera kwa majekeseni, ndikofunikira kukonza makina amafuta pamalo apadera, chifukwa mtengo wa zida zosinthira ndizodabwitsa ndipo palibe chifukwa choyika pachiwopsezo. Pakuti diagnostics wa jekeseni dizilo, kukonza awo ndi m'malo, lemberani https://dizelbox.ru/remont-dizelnyh-forsunok.

Majekeseni a dizilo amtundu wa Delphi solenoid amaonedwanso kuti ndi okonzeka, koma ndi okwera mtengo kumanganso kuposa Bosch. Ichi ndi chifukwa chakuti pambuyo m'malo nsonga (ndipo izi ndi zofunika), muyenera encode, apo ayi galimoto ntchito mosakhazikika.

Ma jekeseni a dizilo a Denso electromagnetic ndi osakonzedwanso. Choyamba, ma nozzles amtunduwu ndi odalirika komanso okhazikika. Kachiwiri, ndizovuta kwambiri kupeza zida zosinthira - nthawi zambiri, zimakhala zofulumira, zosavuta, komanso zotsika mtengo kukhazikitsa zatsopano.

Bosch ndi Delf piezoelectric injectors sangathe kukonzedwa. Ngati pa matenda a Common Rail dizilo jekeseni kusagwira ntchito kwawo kunavumbulutsidwa, ndiye kuti mbali zonse zimasinthidwa kukhala zatsopano.

Koma Continental (kale Siemens) jekeseni dizilo, iwo sanakonzedwe mpaka posachedwapa. Pogulitsidwa kale mutha kupeza malangizo a jakisoni osinthira, ndi ma diameter osiyanasiyana. Chifukwa chake, mutha kusankha njira yoyenera pamphuno iliyonse ndikuyibwezeretsa kuti igwire ntchito pamtengo wocheperako (poyerekeza ndi kugula yatsopano.

Nthawi Yomwe Mungadziwire Ma Injection a Dizilo a Common Rail

Malinga ndi wopanga, moyo wautumiki wa jekeseni wa dizilo wa Common Rail ndi makilomita 100-150. M'zochita, nozzles ambiri amatha kupirira mpaka 150-200 makilomita zikwi. Poganizira za mtengo wa magawo ndi antchito posintha, akatswiri samalimbikitsa kusintha majekeseni a dizilo wamba mpaka mavuto owoneka ayamba nawo.

Ndikofunikira kuti muzindikire majekeseni a dizilo a Common Rail ngati utsi wayamba kusuta kwambiri, kugwiritsa ntchito mafuta kwawonjezeka. Zizindikiro ziwirizi ndiye zifukwa zazikulu zolumikizirana ndi Common Rail Diesel Injector Diagnostic Assistant.

Zomwe zimayambitsa kusagwira ntchito kwa ma jekeseni a dizilo wamba njanji

Tiyeni tiwone mwatsatanetsatane zomwe zimayambitsa kuwonongeka kwa injini yamafuta a dizilo:

• Kutsekereza.

Ngati jekeseni wotsekedwa amapezeka panthawi ya diagnostics ya dizilo wamba njanji jekeseni, mwiniwake akhoza exhale, chifukwa kulephera izi ndi zosavuta ndi zotsika mtengo kukonza.

Zoyenera kuchita: Yatsani singano yotsekeka. Izi zitha kuchitika ndi chotsuka cha ultrasonic kapena pamanja pogwiritsa ntchito scrapers ndi maburashi apadera.

• Kuvala makina ochapira

Pakati pa atomizer ndi kasupe mu jekeseni wa dizilo wa Common Rail pali makina ochapira, omwe pamapeto pake amapunduka ndikutaya kukhazikika kwake.

Zoyenera kuchita: Sinthani makina ochapira.

• Kuwonongeka kwakukulu kapena kuwonongeka.

Zizindikiro kapena zizindikiro zakuvala kwambiri, zomwe zimazindikirika panthawi yomwe ma jakisoni a njanji ya dizilo wamba, zimatha kuwononga thupi. Popeza nyumba sizingasinthidwe padera, gawo latsopano lidzafunika kuperekedwa.

Zoyenera kuchita: Ikani jekeseni watsopano wa dizilo.

• Zokonda za jakisoni ndizozimitsidwa.

Kuchita bwino kwa jekeseni wa dizilo kumatsimikiziridwa ndi magawo angapo: kutsegula kuthamanga, jekeseni wa jekeseni, kuyenda kwa singano, ndi zina zotero. Pankhaniyi, mafuta amawathira papepala, kupanga malo a mawonekedwe enaake.
