I-High Performance Diesel Injector Nozzle DLLA141P2146 Common Rail Nozzle 0433172146 0 433 172 146

1. Intuthu emnyama uma injini kadizili isebenza
Okokuqala, qaphela ukuhlola uhlelo lokunikezela komoya. Uma injini ye-diesel ingenawo umoya owanele, inani lomoya ekamelweni elivuthayo alikwazi ukuhlangabezana nezidingo, okuzokwenza ukuthi idizili ingashi ngokugcwele. Uma udizili ungashi ngokugcwele, kulula kakhulu ukukhiqiza intuthu emnyama ngaphansi kwengcindezi ephezulu. Ngalesi sikhathi, ipayipi lokungena nesihlungi somoya kufanele kuhlolwe ukuze kubonakale ukuthi akukho yini ukuvaleka, ukuthi i-supercharger isebenza ngokujwayelekile yini, nokuthi ingabe kukhona ukuvuza epayipini elingenisayo. Ngesikhathi esifanayo, hlola ukunemba kwe-valve ukuze uqiniseke ukuthi ayikho inkinga yokuvuza ezihlalweni zevalve yokudonsa neyokukhipha umoya, kanye nenkinga yokusondelana kwe-piston, i-cylinder liner, neringi ye-piston. Okwesibili, qaphela ukuhlola uhlelo lokuhlinzeka ngodizili. Uma injini ye-diesel inikezwa kabi ngophethiloli, kuzoba nomthelela ekuxubeni kwakamuva. Ngisho noma ifinyelela esimweni esigcwele sokuthatha, ayikwazi ukushiswa ngokuphelele, futhi umusi omnyama uzokhiqizwa ngalesi sikhathi. Phakathi nenqubo yokuhlola, amaphuzu alandelayo kufanele aqashelwe: Naka ukuhlola iphampu kawoyela enomfutho ophezulu ukuze uqiniseke ukuthi ihlangabezana nezidingo ezijwayelekile. Naka ukuhlola uphethiloli ukuze ugweme ukutholakala kukaphethiloli ngokweqile. Naka ukuhlola isimo sokusebenza kwevalvu yokukhipha uwoyela ukuze uqinisekise ukuthi isesimweni esihle. Naka ukuhlola ukungasebenzi kahle kwe-atomization okubangelwa ukucindezelwa komjovo onganele. Naka ukuhlola umjovo wesibili kanye nokuvuza kukawoyela komjovo. Naka ukuhlola inkinga yamagesi omjovo amaningi kanye nomjovo kaphethiloli ongekho ezingeni. Naka ukuhlola ukusebenza kukadizili kanye nekhwalithi.
2. Amandla anganele enjini kadizili
Ngesikhathi sokusebenza kwenjini ye-diesel, kulula kakhulu ukuba nenkinga yamandla anganele. Lapho uhlangabezana nezinkinga ezinjalo, izindlela eziningi kufanele zisetshenziswe ukuthola imbangela yephutha. Okokuqala, hlola intuthu kanye nezinkinga zokugqoka. Ngesikhathi sokusebenza kwenjini, vula isivalo samafutha. Uma kutholakala intuthu ewugqinsi, kusho ukuthi injini kadizili inenkinga enkulu yokwehla kwentuthu, okukhombisa ukuthi isigubhukane, i-piston, i-piston ring nezinye izingxenye zigugile. Lapho kuvulwa ikhava ye-valve, lapho kuvela intuthu ye-cyan nentuthu emhlophe empandeni ye-valve, kusho ukuthi intuthu ephezulu ivela. Uma kwehla intuthu enkulu phezulu, kusho ukuthi i-valve kanye nesihlalo se-valve kushiswe kakhulu futhi kugugile, futhi kungase kubangelwe ukuvuleka kwevalvu encane noma ukungabi nalutho. Ngokubheka intuthu ephezulu, kungabhekwa ukuthi iyiphi i-valve noma isilinda esinenkinga yokuvuza, futhi izinyathelo kufanele zithathwe ngesikhathi sokubhekana nayo. Okwesibili, hlola amadiphozithi ekhabhoni nezimo zokusebenza. Uma amadiphozithi ekhabhoni emnyama evela endaweni yokukhipha umoya wenjini kadizili, efana nongqimba lwesithwathwa esimhlophe, nogqinsi luncane, kusho ukuthi injini kadizili isesimweni esihle sokusebenza. Lapho kuvela amadiphozithi ekhabhoni amnyama futhi agqamile, kodwa amadiphozithi ekhabhoni awamanzi, lokho kubonisa ukuthi uwoyela wenjini ye-diesel usetshenziswa kakhulu, futhi amadiphozithi ekhabhoni kufanele ahlanzwe kahle. Uma ugqinsi lwamadiphozithi ekhabhoni embotsheni yokukhipha umoya yesilinda lukhulu kakhulu kunakwamanye ama-cylinder exhaust port, kusho ukuthi isijojo sesilinda sisesimweni esihle sokusebenza, futhi isilinda kungenzeka ukuthi asivalwanga kahle, ngakho-ke kufanele sihlolwe futhi kufakwe esikhundleni. Kumachweba okukhipha umshini ngamunye, lapho emanzi noma enamafutha, kusho ukuthi kunomthamo omkhulu wokukhishwa kwamafutha ngaphakathi kwe-cylinder, futhi ukulungiswa kufanele kwenziwe ngesikhathi. Uma ugqinsi lwamadiphozithi ekhabhoni embotsheni yokukhipha umoya isilinda lukhulu futhi umbala umnyama, kusho ukuthi izinga lokushisa liphansi futhi umjovo kaphethiloli awukho, okuholela ezinkingeni ezinkulu zokushiswa ngemva kokushiswa kwenjini kadizili. Kuyadingeka ukuthi uqinisekise ukuthi injini ye-diesel isebenza ngendlela efanele futhi wenze izinguquko zokuthuthukisa.
