Isingeniso somkhiqizo:
Isistimu yomjovo we-diesel fuel i-atomize uphethiloli futhi isakaza phakathi kwezingxenye ezixubene nomoya ekamelweni elivuthayo.
Ikakhulukazi yakhiwe ngomjovo wamafutha kanye nomzimba womjovo.Ama-injection kaphethiloli afakwe ekhanda le-cylinder ahlukaniswe abe izinhlobo ezimbili: uhlobo oluvulekile nohlobo oluvaliwe.Umjovo ovulekile unesakhiwo esilula kodwa i-atomization embi futhi ayivamile ukusetshenziswa.Ama-injection kaphethiloli avaliwe asetshenziswa kakhulu ezinjinini ezahlukahlukene zikadizili.Injini ye-diesel ihogela umoya ohlanzekile ngesikhathi sokushaywa.Lapho ukucindezelwa kwe-stroke sekusondele ekupheleni, uwoyela wedizili uyakhushulwa abe ngaphezu kuka-100MPa ngepompo yomjovo kaphethiloli, ajovwe kusilinda ngomjovo kaphethiloli, ahlanganiswe nomoya ocindezelwe onezinga lokushisa eliphezulu ngesikhathi esifushane kakhulu ukuze kwakheke ingxube evuthayo.Ngenxa yokucindezelwa okuphezulu kwezinjini zikadizili (imvamisa i-16-22), umfutho womoya kusilinda ungafinyelela ku-3.5-4.5MPa ekupheleni kokucindezelwa, futhi izinga lokushisa liphezulu njengo-750-1000K (ngenkathi ukucindezela kwengxube yegesi wezinjini zikaphethiloli ngalesi sikhathi kuzoba ngu-0.6-1.2MPa, izinga lokushisa lifinyelela ku-600-700K), elidlula kakhulu izinga lokushisa lokuzishisa likadizili.Ngakho-ke, ngemva kokuba uphethiloli we-diesel ujovwe ku-cylinder, ngokushesha uvutha futhi ushise ngokwawo ngemva kokuxutshwa nomoya ngesikhathi esifushane kakhulu.Umfutho womoya kusilinda ukhuphuka ngokushesha ufike ku-6-9MPa, futhi izinga lokushisa liphinde lenyuke libe ngu-2000-2500K.Ishayelwa igesi enomfutho ophezulu, i-piston iya phansi futhi ishayela i-crankshaft ukuthi ijikelezise ukuze yenze umsebenzi, futhi igesi yokukhipha umoya nayo ikhishwa emkhathini ngepayipi le-exhaust.
Injini evamile kadizili ishayelwa yi-camshaft yenjini, futhi uwoyela wedizili ulethwa egumbini likaphethiloli lesilinda ngalinye kusetshenziswa ipompo likawoyela elinengcindezi ephezulu.Le ndlela yokuhlinzeka uwoyela kufanele ishintshe ngokushintsha kwejubane lenjini, futhi inani eliphelele lokunikezwa kukawoyela ngesivinini esihlukahlukene alikwazi ukutholwa.Uhlelo olujwayelekile lokuhlinzeka ngophethiloli womjovo wesitimela luqukethe iphampu yamafutha anomfutho ophezulu, ipayipi elivamile lokuphakela uphethiloli, isijovo sikaphethiloli, iyunithi yokulawula i-electronic (ECU) nezinye izinzwa zokucindezela kwamapayipi.Umjovo ngamunye kaphethiloli ohlelweni uxhunywe kuphethiloli ovamile ngepayipi lawo lamafutha anomfutho ophezulu.Amapayipi axhunyiwe, futhi ipayipi elivamile lokuhambisa uphethiloli lisebenza njenge-hydraulic pressure accumulator yomjovo.Lapho isebenza, iphampu kaphethiloli enomfutho ophezulu iletha uphethiloli epayipini lokuphakela uphethiloli lomphakathi ngengcindezi ephezulu, kanye nephampu kaphethiloli enomfutho ophezulu, inzwa yokucindezela kanye ne-ECU kwenza umsebenzi ovaliwe ukuze ulawule ngokunembile ingcindezi kawoyela endaweni kawoyela yomphakathi. ipayipi, ishintsha ngokuphelele umfutho wokunikezwa kukawoyela ngokushintsha kwejubane lenjini.Isimanga.Izici zayo eziyinhloko zimi kanje:
1. Isikhathi sokujova uphethiloli sihlukaniswe ngokuphelele nemitha yamafutha, futhi ukucindezela komjovo kaphethiloli kanye nenqubo yokujova uphethiloli kulawulwa yi-ECU ngesikhathi.
2. Ingcindezi yomjovo kaphethiloli yesilinda ngasinye, indawo yokuqala kanye nobude besikhathi sokujova uphethiloli kungalungiswa ngokuya ngezimo zokusebenza zenjini, ukuze kulandelwe indawo yokulawula engcono kakhulu yomjovo kaphethiloli.
3. Umfutho ophakeme womjovo kaphethiloli kanye nokujova kwangaphambili kukadizili kungafinyelelwa.
