Njani injectors idizili?

Njengoko yaziwa, injini yokuvutha kwangaphakathi kufuneka oksijini ipetroli a ratio ethile. inkqubo amafutha Sam yahlukile kwizithuthi ipetroli nedizili. Kwimeko yokugqibela indima esatsiba inaliti luyenziwa. iinjini Diesel baxhotyiswa oluneentlobo ezahlukeneyo izinto data. Kwinqaku lwanamhlanje siza kuxubusha yintoni i data injector, yintoni iindidi kukho kwaye iSADC ukulungisa ukuba.

feature

Masiqalise ingcaciso. Nemilomo of iinjini diesel - yinto elementi kwinkqubo yonikezelo amandla obonelela kukudla kwigumbi cylinder yokutsha. Indlela ivelisa umsi itshizwe imixube kwi overpiston screen. Kwakhona nemilomo nomthamo ukuvelisa diesel. Ukusebenza, loo nto iya kuvulwa ize ivalwe ukuya umbuzo kweliwaka ngomzuzu.

iintlobo

Kukho iintlobo ezininzi yezi ndlela:

• Electro.
• Piezoelectric.

ngaba ezi zinto yaye zicwangciswe njani injini diesel? Ezantsi thina ukuchaza iimpawu ngamnye kubo.

electro

Ezi imilomo of iinjini diesel efakiweyo izithuthi kunye inaliti le "Common Rail". Izixhobo yale ndlela ibandakanya ubukho izinto ezinjalo;

• Control camera.
• Idreyini kunye umcephe owongozelelweyo.
• Le valve solenoid.

Njani le injectors electro-diesel? algorithm lwabo luxhomekeke ekusetyenzisweni yengcinezelo amafutha ngexesha isitofu kunye nokupheliswa kwayo. Ngenxa yoko, isimo sokuqala, ivelufa esatsiba ivaliwe yaye de-amandla. Indlela inaliti licinezelwe ngci ngokuchasene isihlalo vana hi xi amafutha. Kwesi sikhundla, inaliti wamafutha wenziwa iziqulathi. Ephethwe esatsiba ukusuka bombane. unit control Special ivelisa umqondiso leyo inikezelwa ivalve solenoid. Ngeli xesha, amanzi esatsiba idreyini ukuvula diesel umcephe wokunyusa. Kwamafutha kwemali kuyo kwaye iwela kumgca ngokulahlekelwa. Le Ulwamkelo iibhloko umcephe le Ukulinganiswa ngokukhawuleza iingcinezelo kumgca esingena kwaye kwigumbi yolawulo. Okulandelayo inaliti kuvuswe ngokunxulumene kwisihlalo kunye amafutha ongena egumbini. Emva koko, lo xi ukunyanzela ukuba avuse kunye stroke kwenzeka. Amanzi esatsiba ubuyela endaweni yaso yesiqhelo. Okulandelayo, umjikelo yindlela yokusebenza iphindiwe.

piezoelectric

Ezi imilomo a more eziphuculweyo kuyilo. Inzuzo ephambili yale injectors piezoelectric yi zikhawulelana kangakanani. Isixhobo ivalve solenoid isebenza izihlandlo ezine ngokukhawuleza kunokuba kunoogxa hydraulic. Oku kwenza kube lula ukuvelisa amafutha inaliti ezininzi kumjikelo ngamnye. Le injectors piezo ezifakwe kwinkqubo "Common Rail" isizukulwana esitsha. mechanism ulawulo data ngokusekelwe utshintsho ebudeni yikristale piezoelectric kwindawo ombane kwangaphambili. Uyilo injectors piezoelectric luquka:

• Pusher.
• Inaliti.
• valve Diverter.
• Eyona nto piezoelectric.

Konke oku ligcinwe kwityala encinane. Umgaqo esebenza ngayo iseli isekelwe ukusetyenziswa hydraulics. Njengoko kwimeko yangaphambili, inaliti uhleli esihlalweni ngenxa uxinzelelo amafutha. Kodwa kamsinya nje indlela esifumana i SIGILL, ukwanda ubude element piezoelectric. Ngoko ke ukuvulwa ivelufa utshintshayo. diesel lingena umgca ngokulahlekelwa. Inaliti ngenxa xi ophezulu, nto leyo kwamiswa emazantsi liphume. Ngaloo inaliti yamafutha ikhutshwa phandle. Ucinezelo ezikuyo, amandla stroke kunye exhaust ziyafana. Kodwa ke inani le diesel ukuba lesitofu, kumiselwa xi amafutha kwi kaloliwe amafutha kunye nobude sesichengeni eli element piezoelectric.

zokulungisa

Iziqalelo eziphambili ephuma lwesakhiwo - yile:

• Woopopayi. Ngaba ezisisiseko element "boshevskoy 'umlomo. Siqulathe stem kunye undim. Into yokugqibela kukuba eligugileyo, kunye eyaphukileyo. Kwakhona obuvelisiweyo kunye esiqwini. Ke ukuba iinqwelo usiba, iintanda injectors amafutha emoto ayekwi ngentonga eyaphukileyo akwenzeki. Le nto Awunakugcinwa kwakhona. Kulo mzekelo, lingabali kufuneka itshintshwe.
• డొమైన్ idomeyini. "Bosch" yoMvelisi isiqinisekiso operation inkathazo-free ezilikhulu lamawaka kweekhilomitha. Kodwa kwiimeko zethu, isitshizi wamkhulisa eninzi. Eqalisa ukuba ijam thela amafutha kulo njengesilinda. Indlela yokusombulula le ngxaki? Kwiimeko ezininzi, oko kunceda ukucocwa injectors idizili kunye ultrasound (kuba bedyobhekile kwisibaso yethu). Kodwa ukuba oku akusebenzi, isitshizi kutshintshwe entsha.

Ukulungiswa injectors amafutha emoto ayekwi angangaludingi imoto yakho. Kwanele ukwenza utshintsho ekunene. Kodwa uhlole yokuqala eyenziwa injectors diesel kwi izixhobo ezikhethekileyo. Kakuhle eli hlengiso lula. Yena ke zibonise stroke ivalve solenoid kunye nebhola. Umsantsa siyahlengahlengiswa ngendlela shims. Ngokuxhomekeka kuhlobo esatsiba, ikhondo ilungu ibhola ibe ukusuka milimitha 0,025 ukuya 0,07. Emva kokuba oku ukucwangcisa valve stroke. Kufanele kuphawulwe ukuba ezi imisebenzi lwenziwa kwizikhululo kwinkonzo ezikhethekileyo. Emakhaya, benze umsebenzi onjalo engenakwenzeka.

isiphelo

Injector - into ebalulekileyo nayiphi na imoto diesel. Ukususela kuhle yayo ixhomekeke umsebenzi injini yonke. Ngoko ke, kubalulekile ukuba ukufumanisa ngexesha yaye, xa kuyimfuneko, nokulungiswa injectors diesel. Nangona kunjalo, le ndlela akuthethi uvumele ifowuni ukuba kuveliswe umsebenzi onjalo ngokwabo.
